No description was provided for this meeting.
If this is YOUR meeting, an easy way to fix this is to add a description to your video, wherever mtngs.io found it (probably YouTube).
A
A
We've
had
a
problem
yesterday,
as
most
of
you
experienced
with
the
pbs
scheduling
and
as
soon
as
we
finished
the
office
hours
ceso
engineers
were
able
to
identify
and
fix
the
problem,
so
that
was
around
3
p.m.
I
want
to
just
say
a
big
thanks
to
ceso
for
doing
that,
and
also
it
was
frustrating.
It
was
frustrating
for
me
as
well
like
experiencing
this,
but
this
is
part
of
our
life
like
working
with
a
super
computer.
A
It
happens.
It's
not
unfrequent
that
that
kind
of
problem
happens,
and
I
just
want
to
remind
everyone
that
if
you
rather
any
other
system,
experience
a
problem
on
the
supercomputer
there's,
always
a
team
of
experts
on
behind
the
scenes
that
are
there
to
help
us.
In
the
case
of
the
the
cheyenne
and
casper
supercomputers,
we
have
the
sizzle
user
support.
You
can
email
sizzle
help
or
you
can
call
this
line.
There's
always
someone
available
to
help
and
they're
pretty
quick
and
responding
to
the
issues
that
we
face.
So
please
take
advantage
of
that.
A
A
reminder
we've
already
closed.
The
poll
for
today's
land
model
q,
a
but
the
ones
for
tomorrow
and
friday
are
still
open
and
they
will
close
5
p.m.
The
day
before
the
the
session.
So
please
submit
your
your
questions
as
soon
as
possible
and
then
finally,
I
just
want
to
see
if
there's
any
other
comments
or
questions
from
from
you
guys
before
we
would
pass
to
peter
and
the
lynn
modelers.
A
I
know
there's
a
question
on
chat
related
to
having
trouble
with
create
a
new
case
and
also
see
another
one,
psn
merchandise,
okay,
so
the
first
question
we
will
sort
it
out
on
the
office
hours
today.
The
morning
session
will
be
dedicated
to
the
theoretical
part
related
to
the
land
model.
So
if
you
want
to
reach
out
to
me
in
in
a
separate-
maybe
we
can
you
know
in
between
like
off
of
lunchtime
and
keep
meeting
and
try
to
work
together,
but
if
not,
they
learn
during
lunch
time
during
the
office.
A
A
A
C
Thanks
gustavo
yeah,
it's
exciting
to
be
here
and
to
see
everybody
online
and
thanks
for
everyone
joining
I'm
going
to
put
up
a
powerpoint,
and
I
haven't
used
this
computer
before
with
sharing.
So
it
could
be
a
little
confusing.
But
I'm
going
to
start
with
this.
C
And
tell
me
if
that's
sharing
fine
gustavo,
can
you
yeah.
A
A
C
Okay,
I'm
just
yeah,
so
I've
got
a
big
screen.
I
haven't
used
it
before
for
sharing
so
okay.
So
what
I
wanted
to
start
off
with
is
like
just
taking
you
through
the
the
land
q
and
a
session
and
big
big
thanks
to
dave
lawrence,
daniel
kennedy,
danica
lombardozzi,
katie,
diagon,
keith,
ellison
and
we'll
leader,
who
are
going
to
help
out
with
many
of
the
questions
we
come
up
with
today.
C
So
I
guess
the
first
thing
I
want
to
do
is
like
go
into
the
the
the
quiz
that
we
sort
of
put
out
there,
and
this
quiz
wasn't
really
to
test
your
knowledge.
It
was
more
to
get
you
thinking
about
the
land
model
and
what
sort
of
things
you
can
do
with
the
land
model
in
your
research,
I'm
going
to
go
through
and
gustavo's.
Okay,
if
I
put
the
answers
to
the
quiz
here
or
is
that
you.
C
Right,
sorry,
I
didn't
realize
that
so
I
want
to
just
skip
through
that
quickly
and
we'll
start
off
with
the
quiz
and
then
I'll
go
through
the
answers
to
it.
When
we've
we've
done
the
quiz.
Sorry
I
didn't
realize
that
was
something
that
hadn't
done
yet.
A
C
And
yeah,
and
to
think
about
this
is
just
more
just
to
get
you
thinking
about
like
the
model,
rather
than
like
really
testing,
whether
you've
studied
up
on
the
model
or
what
what
the
implications
are
so
just
fill
it
out
and
yeah
as
we
go
through
it.
You
can
just
answer
the
questions
as
you
sort
of
see
fit
to
what
you
would
expect
and
what
you
think
about
the
model
and
how
it
works.
A
Work
elizabeth
can
see
how
many
people
have
responded.
The
percentage
and
can
you
can
you
tell
us,
is
about
when
we
reach
like
around
75
or
so
I
can
yeah
that
doesn't
take
too
long.
It
did
not
come
up.
A
D
C
All
right:
well,
you
know
it's
it's
fine,
because
it
really
was
more
to
get
people
thinking
about
it
rather
than
trying
to
demonstrate
people's
knowledge
of
the
model
so
having
gone
through
the
the
quiz.
What
I
might
do
is
just
just
go
through
through
the
answers
very
quickly,
and
do
you
want
to
wrap
that
up
in
a
little
bit
elizabeth?
I
should.
C
Okay
and
what's
sort
of
really
interesting
when
we
think
about
the
model
is
it's
a
quiz
across
here
for
a
second
is
that
there
are
a
lot
of
human
processes
that
we
represent
in
clm,
and
what
we're
trying
to
do
is
try
and
understand
both
how
we
represent
the
processes
and
the
effect
on
the
climate,
but
also
how
climate
impacts,
human
processes
so
start
living
in
an
impact,
modeling
sense,
and
so
what
I
did
here
is
just
put
a
few
of
the
different
types
of
human
processes
that
we
we
do
have
represented
in
the
clm
model.
C
But
there
are
certain,
there's
still
a
large
number
of
processes.
We
don't
include-
and
in
this
case
it
was
co2
emissions
from
ground
transport
transportation,
which
would
be
very
difficult
to
actually
simulate
in
the
model.
You
could
start
thinking
about
how
you
would
do
that,
but
it's
a
complex
process
where
you'd
have
to
represent
all
the
transport
and
humans
and
what
was
happening.
So
this
is
one
of
the
process
we
don't
represent,
but
as
the
model
goes
on,
we're
trying
to
increase
its
complexity
and
its
representation.
C
So
this
may
be
something
that
gets
included
in
a
future
version
going
to
the
next
next
question
yeah.
Basically,
what
I
really
wanted
to
do
is
say
yeah.
All
these
things
are
a
part
of
what's
going
on
in
terms
of
the
the
representation
of
how
complex
the
the
land
surface
is
so,
instead
of
seeing
where
we
started
off
in
the
the
1980s
and
1990s
was
we
had
the
single
grid
cells,
which
were
just
this
one
representation
of
what
the
land
surface
looked
like
communicating
with
the
atmosphere?
C
Now
we
have
this
really
complex
hierarchy
of
land
units
and
land
cover
classes
within
that,
and
each
of
those
has
a
different
set
of
properties
and
a
different
sort
of
fluxes
to
the
atmosphere,
and
I
just
really
wanted
to
get
you
thinking
about.
Well,
how
do
you
represent
that
really
sort
of
like
that
really
complex
heterogeneous
landscape
in
the
model
so
and
pretty
much?
Everyone
said:
that's
exactly
that.
That
was
what
the
model
does,
so
that
was
really
good
getting
to
the
next
question.
C
Yeah
again,
I
start
just
want
to
get
some
idea
of,
like
you
know,
there's
all
these
complex
things
happening
in
terms
of
how
the
way
the
environment
is
impacting
plants
and
how
we
represent
them
and
also
the
way
we
represent
the
complexity
of
the
land
surface.
But
there's
still
a
lot
of
things.
We
don't
actually
capture
and
yeah
pretty
much.
Everyone
worked
out
that
it
was
insect
outbreaks
that
we
don't
currently
model
in
the
mod
in
in
clm.
You
know
it's
it's
one
of
those
things
that
it's
the
complexity
of
trying
to
get
the
populations.
C
Going
yeah,
okay,
great
this
one
was
really
just
to
get
you
thinking
about.
There's
just
so
many
different
ways
we
can
configure
out
the
csm
model,
and
a
big
part
of
that
is
is
understanding
how
much
control
you
have
over
which
parts
the
model
are
on
or
off,
based
on
the
configuration
you
choose
and
it
wasn't
really
to
test
with.
You
knew
all
of
these
configurations
and
what
they
did.
It's
just
more.
C
The
idea
that
there
are
standard
configurations
and
then
when
we
went
through
in
we'll,
go
through
there's
a
query,
config
tool
which
goes
through
in
the
practical
session
where
we
go
through,
and
we
can
see
how
you
tell
clm
which
components
are
on
and
which
components
are
off
for
a
particular
configuration
and
yeah.
I
didn't
want
to
make
this
too
confusing,
so
yeah
they're,
all
all
of
them
are
true,
so
none
of
them
are
actually
those
statements
are
files,
so
I
think
everyone
sort
of
worked
that
one
out.
C
The
final
question
I
have
was
like
thinking
about
spin-up
times
and
getting
the
model
into
equilibrium.
So
the
question
is
actually
a
trick.
Question
which
I
think
most
people
realize
is
the
fact
that
it
depends
on
which
processes
you're
really
interested
in
and
what
your
initial
conditions
are.
So,
if
you're,
starting
from
initial
conditions
that
are
spun
up
and
working
with
the
current
climate
that
you're
looking
at
yes,
the
model
will
be
pretty
much
in
equilibrium
when
you
start,
but
it
can
take
thousands
of
years
to
bring
the
carbon
cycle
into
equilibrium.
C
It's
really
important
to
think
about
that
when
you're,
when
you,
when
you're
running
the
model
and
when
you're
setting
up
and
doing
experiments
with
it,
you
can't
just
take
the
model
and
like
run
it
without
doing
enough
thought
about
what
is
the
model
in
equilibrium
with
and
if
I'm
going
to
do
some
form
of
sensitive
experiments
or
look
at
some
form
of
transient
historical
or
paleo
run.
C
You
know
10
years
to
get
the
hydrology
into
configuration
up
to
thousands
of
years
to
get
the
carbon
cycle,
and
so
one
of
the
practical
ways
you
can
get
around
that
is
always
sort
of
like
think
about
what
initial
conditions
am
I
going
to
use
for
this,
and
we
have
a
whole
range
of
initial
comp
conditions
for
clm
that
have
been
spun
up
within
the
land
model
working
group
and
at
ncar
and
working
with
us
to
like
actually
work
that
out.
C
It's
really
important,
so
I
just
really
wanted
to
get
that
people
thinking
about
that
as
like
the
final
part
of
the
the
quiz.
So
it
was
yeah
really
good.
If
people
have
any
questions
about
that,
I'm
happy
to
start
discussion
on
that
or
we
can
go
to
the
questions
that
were
posed
through
the
through
the
the
website.
C
I'm
happy
to
do
either
of
those
so
maybe
we'll
just
like
at
the
end
of
the
quiz,
we'll
we
can
sort
of
have
a
discussion
or
if
any,
anyone
else
from
the
the
panel
wanted
to
speak
about
any
of
these
as
well.
I
have
something
they
want
to
add
very
happy
to
do
that
now.
C
Okay
right
well,
maybe
we'll
just
move
on
to
some
of
the
online
questions
that
were
posed
through
the
chats
through
the
the
the
query.
C
So
the
first
question
was:
does
clm5
provide
a
single
column
version
for
parameterization
testing
and
the
answer
is
yes,
the
model
can
be
run
in
point
mode
with
forcing
data,
and
you
can
also
you
can
also
couple
it
to
cam
in
single
atmospheric
column
mode,
so
that
that's
one
way
that
you
can
run
the
model
and
you
can
definitely
do
parameterization
testing
that
way.
There's
a
lot
of
other
ways.
You
can
do
like
understanding,
familiarization
sensitivity
which
we'll
get
into
which
we
can
get
into
in
the
discussion
a
little
later
from
other
questions.
C
But
the
answer
is
yes.
This
can
be
done
in
a
single
point
rather
than
run
globally
or
for
a
sort
of
a
fixed
domain.
What
are
the
priorities
for
things
to
change
in
future
versions
of
clm?
And
this
is
a
really
good
question.
It's
really
sort
of
open
and
there
are
many
components-
we're
trying
to
look
at
right
now,
so
from
crop
representation
through
to
full
ecosystem
modeling
with
fades.
Well
dave.
Danica.
Do
you
want
to
step
in
on
this
one?
So
what
are
the
priorities
going
forward
on
this?
C
Do
you
have
just
a
quick
one,
so
one
or
two
pieces
that
you
can
add
to
that
and
dave
or
well
yeah.
E
Sure
I
can
go,
I
said
yeah,
I
guess
there's
two
probably
two
main
developments,
I
would
say,
are
kind
of
the
up-and-coming
big
improvements
to
cllm,
and
so
one
of
them
peter
mentioned,
is
fates,
which
is
the
functionally
assembled
terrestrial
ecosystem
simulator.
So
that's
a
way
of
starting
to
think
about
the
role
of
disturbance
and
how
disturbance
affects
the
structure
of
ecosystems,
and
it
also
kind
of
removes
the
prognostic
we're
going
to
tell
the
model
where
plants
grow
and
in
like
fully
you
know
fully
running
fates,
fates.
E
So
that's
more
kind
of
on
the
ecosystem
side
of
things
and
then
on
the
hydrology
side
of
things.
I
think
the
hill
slope
model
that
sean
swenson
is
developing
is
is
probably
the
most
exciting
development
that'll
be
coming
into
future
versions
of
the
model
so
sean's
got,
and
the
idea
between
behind
the
representative
hill
slope
model
is
that
you've
got
uplands
land
units
that
are
hydrologically
connected
to
lowland
land
units.
E
So
the
uplands
might
be
dry,
the
lowlands
might
be
wet,
there's
also
a
sense
of
aspect
as
well
as
precipitation
downscaling,
so
that
mountaintops
and
the
model
get
more
snow
than
the
valleys,
for
example.
So
it
again
allows
us
to
increase
this
kind
of
subgrid
heterogeneity
that
the
models
you
know
with
one
set
of
atmospheric
inputs
from
cam
or
from
from
re-analysis
we're
able
to
kind
of
capture
more
of
the
subgrid
variability.
That
happens
especially
related
to
hydrology.
So
it
wasn't
a
short
answer,
but
that.
C
E
And
and
daniel
dropped,
I
think
that's
probably
sean's
paper
on
the
preliminary
work
from
the
hill
slope
model.
There's
a
lot
more
that
he's
done
since,
since
that
paper
came
out.
C
C
Okay
next
question:
how
do
we
quantify
and
reduce
uncertainty
in
the
land
service
model
such
as
clm,
and
so
there's
a
number
of
things
we
do
and
the
first
one
is
we
sort
of
analyze
the
modeling
results
and
we
can
confront
them
with
observations
for
the
historical
period
and
one
of
the
key
tools
we
have
for
that
is
this
tool
ilam,
which
is
a
benchmarking
tool,
and
so
what
we
do
is
we
allow
the
model
to
be
compared
to
a
large
range
of
observational
products
and
see
model
biases
and
model
model
relative
scores
across
a
range
of
metrics,
the
other
one
we
do
is
we
look
at
model
into
comparisons
such
as
the
coupled
model
in
the
comparison
project
cmf6,
which
is
where
we
see
large
larger
system,
modeling
simulations
done
by
modeling
centers
all
over
the
world,
and
we
compare
the
results
that
come
out
of
those
and
so
and
then
there's
just
the
normal
process
by
you
know,
analysis
and
writing
papers
to
being
able
to
understand
what
the
model
does
and
sort
of
documenting
that
we
also
have
an
active
parameter,
uncertainty
investigations
that
are
occurring
with
understanding
how
certain
parameters
affect
the
both
the
carbon
cycle
and
the
surface
climate
response
of
the
model
we're
getting
into
it
a
little
bit
later,
so
I'll
most
probably
skip
that
to
a
future
question.
C
C
So
the
next
question
is
parameter
tuning
required
for
running
clm
5
and
if
yes,
are
there
internally
supported
tools
or
external
tools
used,
so
the
cm5
model
itself
has
been
extensively
tuned
to
get
the
best
results
for
the
current
day
in
historical
transient
climates
for
csm,
and
also
for
when
we've
got
land
only
configurations
where
we're
configuring
when
we're
simulating
it
with
meteorology,
either
re-analysis,
meteorology
or
observed
meteorology.
C
But
there
are
ongoing
efforts
to
understand
the
premise,
engines
and
uncertainties
within
the
csm
model,
land
model
working
group
and
danny.
Do
you
want
to
have
a
little
bit
of
a
contribution
here
and
just
sort
of
like
maybe
suggest
how
that
project
is
going
and
what's
involved
with
that?
Just
so,
we
can.
A
Yeah
yeah
I'm
daniel
kennedy,
I'm
a
postdoc
at
ncar
and
I've
been
working
primarily
on
this
parameter.
Perturbation
experiment
they're
about
we
found
about
200
tunable
parameters
in
clm,
and
we
all
work
together
to
come
up
with
ranges.
E
Reasonable
ranges
for
those
parameters
and
now
we're
doing
a
big
experiment,
testing.
A
A
Perturbing
them
in
a
multi-factor
way
and
what
we're
hoping
to
find
out
is
you
know
how.
C
Yeah,
brilliant
thanks
a
lot
daniel,
that's
yeah
and
I
think
we're
gonna
get
back
to
that
in
a
little
another
question
so
we'll
get
on
to
that
then
peter.
Can
I
expand.
B
On
that,
just
a
little
bit
absolutely
that
the
tuning
that
went
on
for
for
say,
for
example,
clm5
within
csm
2
was
was
all
hand
tuning
so
expert
judgment
and
adjusting
parameters
based
on
experimentation
with
the
model
rather
than
any
automated
tuning
algorithm.
And
what
daniel
said
is
we're
hoping
to
move
towards
something.
That's
more
automated,
but
it's
very,
very
challenging
to
do
automated
tuning
for
a
global
model
with
many
different
plant
types,
many
different
ecosystems
and
eco
regions
around
the
world,
and
so
I
don't
think
any
group.
B
You
know
the
other
major
modeling
groups
has
successfully
solved
this
problem
yet
either
and
we
don't
know
if
we
will.
So
it's
a
challenge
and
it's
a
big.
It
is
a
known
limitation
with
these
models
is
that
is
these.
You
know
the
really
uncertain
parameters
and
the
large
number
of
parameters.
C
Yeah
absolutely
yeah
thanks,
okay,
so
the
next
question
was
insulin.
Five
impact
of
ozone
is
also
added.
How
good
is
ozone
parameterization?
What
are
the
additional
processes
required
to
improve
the
impact
of
ozone
on
plant
growth
processes?
And
so
yes,
I
was
going
to
say.
Yes,
I
do
know
that
it's
actually
implemented
and
there
are
ongoing
work
going
with
it.
But
this
is
a
project
that
danica
lombardosi
is
like
the
the
chief
person
on.
So
I'm
going
to
hand
over
to
danica
if
you're,
if
you're
on
danuca.
D
Yep
yeah,
I'm
on
so
the
ozone
parameterization
in
clm5.
Well,
it
exists
it's
there,
but
it
is
not
turned
on
by
default,
so
you
have
to
do
that
and
we
haven't
actually
we.
It
was
developed
in
clm
4.5
and
was
tested
and
evaluated
in
that
model,
but
not
as
extensively
in
clm5
with
all
the
changes
that
came
in.
So
I
guess
those
are
the
caveats.
The
way
that
it's
represented
is
that
ozone
decreases
both
photosynthesis
and
stomatal
conductance
directly
and
then
all
downstream
processes
are
affected.
D
So
we
are
there's
currently
working
on
the.
I
guess.
The
other
piece
to
the
ozone
representation
in
clm5
is
that
currently
the
ozone
concentration
is
not
something
that
is
connected
to
any
file
or
the
atmosphere
model.
So
that's
something
that
you
have
to
do
on
your
own,
but
we
are
in
the
process
of
adding
the
hooks
actually.
So
I
think
some
of
those
pull
requests
are
getting
resolved
this
week
even
to
connect
the
atmosphere
model
ozone
to
the
clm
ozone.
C
Thanks
doctor
yeah,
that's
excellent
yeah,
and
so
it's
an
ongoing
project
and
like
if
you,
if
you
have
more
that
you'd
like
to
talk
about
danica's.
Obviously
the
person
to
talk
to.
D
C
Great
thanks:
okay
next
question
does
cm5
consider
changing
plant
mechanism
processes,
eg
photosynthesis
and
transpiration
due
to
diffuse
and
direct
light.
Also
is
uv
radiation
on
photosynthesis,
parameterizing
c115.
So
for
the
first
part
of
the
question.
Yes,
we
have
direct
and
diffuse
visible
and
near-infrared
light
are
explicitly
represented,
and
so
they
represent
through
the
two-stream
radiation
model
in
clm5
and
at
a
leaf
level.
Radiation
absorption
is,
is,
is
directly
explicitly
stimulated.
C
C
So
that's,
obviously
an
area,
that's
open
for
further
investigation,
but
yes
so-
and
there
are
ongoing
studies
looking
at
the
role
of
cloud
scattering
of
light
to
get
the
direct
diffuse
components
and
whether
that
had
what
impacts
you
have
from
from
radiation
scattering
and
diffuse
versus
direct
components
through
the
canopy.
There
are
some
unexpected
ways
that
direct
versus
diffuse
light
works
in
terms
of
canopy
radiation
and
especially
in
terms
of
how
much
light
gets
through
to
shaded
leaves
than
the
canopy.
C
Okay,
are
the
land
use
land
cover
changes
update
annually?
In
climb,
or
can
they
progress
at
a
prescribed
time
to
make
land
use
land
cover
change
process
more
realistic,
so
the
default
way
we
do
it
in
clm5
is
to
do
it.
On
january,
1st
of
each
year
the
land
use
land
cover.
Change
is
updated
previous
versions.
We
actually
did
it
on
the
on
the
the
half
hour
times
time
step
of
the
model.
C
One
of
the
things
we
ran
into
with
that
was
that
wood
harvest
ended
up
being
really
really
small
increments,
rather
than
being
episodic
events
which
had
some
pretty
big
impacts
in
terms
of
the
way
that
we
understood
land
like
the
wood
harvest.
So
we
went
to
this
january
first
component.
C
One
of
the
things
we
didn't
want
is
to
have
this
large
instantaneous
burst
of
carbon
fluxes,
which
would
be
associated
with
that
land
cover
change
event
on
the
first
of
january.
So
what
we
do
is
we
actually
release
the
carbon
from
those
instantaneous
land
use
effects
across
the
whole
year,
rather
than
just
like
as
a
big
pulse
on
january
1st.
That's
so
the
atmosphere
doesn't
see
this
sort
of
crazy
sort
of
burst
of
carbon
coming
out
globally.
C
You
can
actually
choose
the
the
time
stepping
that
you
want
for
the
land,
use
land
cover
change,
but
by
default
it
is
this
january
first
component,
and
unless
you
really
think
about
it,
I
think
that's
most
probably
the
best
way
to
keep
on
running
the
model.
For
now
the
idea
that
you
would
like
to
be
able
to
set
up
for
a
particular
site,
you
can
still
do
an
event
at
a
particular
point
in
time.
C
So,
if
you're
running
the
model
say
for
a
limited
domain,
you
could
do
that
if
you
want
to,
but
in
this
global
configuration
and
the
way
it
defaults
it
up.
It's
done
on
january
1st
next
question:
how
is
land
cover
change
handled
in
paleo
simulations
where
there
are
no
historical
data
sets
to
use
for
as
imports,
and
the
answer
is
well.
We
have
this.
C
What
we
call
no
anthro,
no
anthropogenic
configuration
for
vegetation
distributions
prior
to
human
disturbance,
and
that
basically
allows
us
to
do
like
basically
through
the
the
holocene
period,
which
is
sort
of
like
very
similar
climate.
To
current
day,
when
we
get
outside
of
like
the
holocene
climate,
we
need
to
start
looking
at
vegetation
reconstructions
based
on
climate,
looking
at
where
you
would
find
ice
sheets
and
those
sort
of
components,
and
that's
a
project
that
the
paleo
group
do
a
lot
of
work
with.
C
So
we
do
the
last
glacial
maxima,
or
we
do
other
periods
sort
of
in
deep
time
so
there
and
in
this
component,
you're
actually
prescribing
this.
You
have
to
construct
up
the
plan,
functional
type
distributions
for
the
period
of
time.
You
look
at.
Obviously
you
wouldn't
be
doing
human
land
use
at
those
sort
of
time
periods,
because
there
were
no
humans
actually
around
to
do
things
like
that.
C
So
what
we
have
is
typically
static:
vegetation
distributions
for
those
reconstructed
periods,
one
of
the
nice
things
about
fates,
which
is
going
to
be
this
new
ecosystem
model.
That
we'll
have
running
is
that
you
have
the
potential
there
to
have
the
model
responding
to
climate
and
finding
new
equilibrium,
vegetation
distributions
and
getting
the
bio
by
climatic
distributions
of
the
that
vegetation
based
on
a
previous
climate
period.
C
What
I've
just
shown
here
is
basically
the
idea
of
like
how
tree
cover
occurred
through
the
time
period,
sort
of
from
six
thousand
years
before
comedy
era
through
to
current
day
and
then
sort
of
future
projections
out
of
tree
cover
under
different
socioeconomic
scenarios.
So
this
is
the
sort
of
way
we
represent.
Land
use
land
cover
change,
I'll
get
to
the
next
question
as
well.
I
think
so.
The
next
question
is:
oh,
no
sorry!
This
is
looking
at
the
carbon
cycle,
so
the
carbon
cycle
as
well.
This
is
the
next
question.
C
C
So
I'm
not
sure
if
this
is
actually
true,
if
there's
a
huge
difference
in
terms
of
the
representation
quantification
between
nitrogen
carbon
cycles,
I'm
open
to
someone
else
taking
this
as
like.
This
is
kind
of
it's
a
big
question
in
terms
of
co2
fertilization
and
nutrient
limitation,
and
we're
doing
a
lot
of
work
on
this.
But
I'm
not
sure
this
is
actually
as
well
defined.
As
this
question
has
put
it
out
there
in
terms
of
the
research
and
and
scientific
knowledge.
Does
someone
else
from
the
group
want
to
talk
about
that?
C
Maybe
dave
or
will,
or
somebody
else
happy
to
let
someone
step
in.
E
Sure
yeah,
I
guess
I'm
trying
to
figure
out.
I
guess
I'm
not
a
little
fuzzy
on
the
question.
I
guess
and
maybe
whoever
asked
the
question
could
raise
their
hand
to
clarify.
E
I
guess
you
know
with
that
what,
if,
if
that
person
does
or
doesn't
want
to
step
forward,
I
will
say
that
there's
pretty
significant
improvements
to
how
we
think
about
the
plant
on
the
plant
side
of
the
representation
of
nitrogen
limitation
in
the
model
and
there's
still
quite
a
bit
of
work
to
be
done
on
the
soil
side
and
in
thinking
about
plants.
Oil,
competition
for
nitrogen
that
are
less
well
resolved,
and
I
can
point
I'll
drop
in
and
chat
a
minute
to
a
paper
that
I
led
in.
F
E
Clm
5
documentation,
suite
of
papers
that
showed
that
clm5
is
much
less
sensitive
to
nitrogen
limitation
than
previous
versions
of
the
model,
and
it
does
show
a
stronger
sensitivity
to
the
co2
fertilization
effects,
but
both
of
those
seem
to
be
in
the
right
direction
relative
to
previous
versions
of
the
model.
So
there's
definitely
work
to
be
done.
I
think
coupled
carbon,
nitrogen
biogeochemistry
is
one
of
the
harder
things
that
clm
is
trying
to
do
and.
C
E
C
And
I
I
would
also
say
that
you
can't
do
the
carbon
cycle
without
the
nitrogen
cycle.
Like
it's.
You
know
you
can
do
some
representation
of
the
carbon
cycle,
but
the
two
are
so
tightly
linked
and
coupled
that
the
idea
that
we
have
one
that
works
really
well
and
one
that
doesn't
it's
probably
like
a
misnomer.
C
Okay,
next
question:
how
to
get
started,
working
on
the
improvement
of
the
crop
mechanical
process
in
cm5
and
improve
the
model.
So
this
is
a
great
question
and
I'm
going
to
throw
this
out
to
danica,
because
danica
is
leading
a
project
looking
at
including
appsim
model
capabilities
in
clm
crop
and
so
I'll
hand
it
over
to
you
darkroof.
That's
okay,.
D
Yeah
thanks:
there
are
many
ways
that
you
can
get
started
on
working
on
the
crop
model
and
we're
we're
still
currently
using
the
existing
crop
model
and
that
one
will
continue
to
work
within
clm,
but
we're
also
developing
new
capabilities.
D
D
There
are
multiple
different
crop
types,
the
way
that
the
new
model
being
integrated,
which
is
going
to
be
it's
going
to
be
called
clm
axis,
and
basically
that's
going
to
allow
for
more
flexible
phenology
and
allocation
schemes
that
can
allow
for
different
numbers
of
phenological
phases
and
stages
by
crop
type,
and
also
different
types
of
stress
during
those
different
phenological
phases.
And
so
it's
going
to
be
an
improvement.
It's
still
a
work
in
progress,
we're
starting
to
get
closer
to
having
all
the
hooks
connected
with
clm.
So
we
can
start
doing
some
basic
testing.
D
But
it's
still
going
to
take
some
time
to
develop,
so
I
would
say
if
you
want
to
start
working
on
it,
you
can
you're
welcome
to
email
me
if
you'd
like
and
we
can
talk
more
but
yeah.
Otherwise
you
know
talk
to
any
of
us.
I
guess
I
should
say,
and
we
can
we
can
help
point
you
in
the
right
direction.
C
Great
thanks
so
much
okay,
next
question,
I
learned
each.
I
learned
that
each
component
of
the
csm
can
be
run
independently
or
combine
eg
clm
cam.
If
I'm
interested
in
the
land
atmosphere,
a
net
lab
airland
exchange,
and
I
only
want
to
have
cam
and
clm.
Are
there
still
working
interactions
through
the
coupler
or
is
it
or
is
there
a
channel
that
connects
to
two?
And
so
what
I'm
going
to
say?
Yes,
the
app
configuration
when
you
set
it
up
with
clm
and
cam
runs
directly
through
the
coupler.
C
So
what
we
do
is
the
coupler
is
able
to
take
either
data
products
or
fully
coupled
products
and
the
different
configurations
tell
which
models
will
be
active
and
how
the
coupler
will
will
be
handling
those,
but
when
we
run
it
in
an
f
configuration
where
we,
what
we
call
amip
we're
basically
telling
the
ocean
and
the
sea
ice.
This
is
where
you
would.
This
is
where
you
are.
C
This
is
how
you're
going
to
evolve,
sort
of
a
monthly
month-to-month
basis
and
the
atmosphere
and
the
land
then
run
so
it
takes
out
one
degree
of
the
sort
of
feedbacks,
and
so
you
don't
get
ocean
feedbacks.
You
don't
get
sea
ice
feedbacks.
It
allows
you
to
be
able
to
sort
of
like
more
precisely
look
at
the
response
between
the
atmosphere
and
the
land.
One
of
the
things
to
think
about
is
yes,
it's
exactly
the
same.
C
There's
just
the
coupler
is
like
taking
data
from
the
other
models,
rather
than
looking
at
having
dynamically
interacting
models
from
the
other,
those
sea
ice
and
see
and
and
ocean
processes.
So
the
next
question.
So
this
was
a
follow-up
question
to
that
one.
How
does
cam
use
the
ceiling
outputs
as
inputs?
For
example?
C
How
can
cam
cam
use
the
nh3
fluxes
generated
from
fan
the
this
fan
model,
which
is
they
put
a
gen?
I
put
a
paper
in
here
from
veradale
as
emissions
input
to
carry
out
atmospheric
chemistry
modelling.
I
studied
the
budgets
of
nh3
into
the
atmosphere,
and
so
what
I
was
going
to
say
here
is
my
initial
response
to
this
is
basically
nh3.
E
Yeah
so
his
background,
so
fan
is:
what
does
it
stand
for
fluxes
of
agricultural,
nitrogen
or
something
like
that
anyway?
It
it's
a.
It
allows
for
prognostic
simulation
of
nh3
flexes
from
fertilizer
and
manure
application
to
the
atmosphere,
and
we
don't
have
so
that's
that's
the
exciting
part
about
fan.
Is
this
prognostic
handle
handling
of
ammonia
emissions?
E
E
It's
a
little
bit
of
a
circular
answer,
so
it's
the
capability
is
there,
but
I
don't
think
it's
very
robust
for
folks
that
are
interested
in
having
these
nitrogen
species
and
and
methane
for
that
matter
actually
be
passed
from
the
land
to
the
atmosphere.
I
think
that's
a
it's
an
open
avenue
of
research
that
people
can
explore.
B
Here
can
I
expand
real,
quick
and
just
in
general,
you
know,
fluxes
of
any
species
can
be
passed
back
and
forth
between
cam
and
clm,
and
it
just
requires
a
relatively
minor
additions
to
the
coupler
and
the
component
models.
And
so
we
are,
you
know,
so
we're
always
adding
new
flexes
of
these
speeches
as
new
processes
are
developed
or
we're
trying
to
get
new
couplings.
B
So
I
could
just
explain
the
ozone
one
is:
is
one
we're
working
on
now?
We'll
talked
about
them,
the
reactive
nitrogen,
but
we
you
know,
we
already
emit
biogenic
voltage,
volatile
organic
compounds
in
the
atmosphere
which
which
they
use,
that
we
emit
dust
from
the
land
and
other
chemical
species,
but
methane,
for
example,
is
not
being
passed
to
the
atmosphere,
even
though
we're
calculating
it,
partly
because
we
don't
have
similar
flexes
from
the
ocean
model.
Yet
so
this
coupling
is
always
sort
of
a
the
technical
challenges
are
small.
B
C
Great
perfect,
okay,
next
question:
is
it
possible
to
run
a
basic
case
and
transfer
model
outputs
from
that
simulation
to
local
environment,
which
can
then
be
used
for
my
own
study,
for
instance?
If
I
I
do
need
soil,
moisture
content
data,
both
actual
and
or
saturated?
It's
still
am
I
able
to
produce
that,
and
so
I
was
sort
of
thinking
about
this
question,
and
definitely
I
mean
if
you,
if
you've
run
the
model
and
you
and
it
takes
a
little
bit
of
work.
C
But
you've
got
all
these
net
cdf
history
files
and
they
can
be
converted
to
a
range
of
formats
and
resolutions,
either
through
tools
like
python
or
or
idl,
or
other
analysis
tools
that
you
have
and
then
you
can
either
load
them
up
into
a
gis
package
like
arcgis
or
if
that's
what
you're
looking
at
the
other
side
of
it
is-
and
I
was
trying
to
think
of
the
question:
can
you
prescribe
soil
moisture
back
into
the
model,
and
that
is
something
you
can
do
as
well?
C
So
and
if,
if
that,
if
anyone
wants
to
like
maybe
expand
on
that
or
maybe
we'll
just
leave
it
there,
it's
yeah.
Okay,.
E
I
guess
I
can
add
a
little
bit
more,
and
so
it's
not
just
soil
moisture.
So,
for
example,
I'm
a
soil,
bio
geochemist
and
have
this
kind
of
standalone
model
that
plays
next
to
clm
and
uses
clm
inputs,
but
it
doesn't,
it
doesn't
feed
back
into
clm.
So
it's
a
it's
a
way
that
you
can
kind
of
develop
a
toy
model.
This
is
the
way
fan
was
developed.
Also,
you
can
develop
a
model
that
uses
the
outputs
for
clm
to
run
whatever
it
is
that
you're
interested
in
that
could
be
a
grid
cell.
E
C
C
If
you
find
a
study
by
someone
who
uses
csm
is
really
advancing
the
understanding
of
some
processes,
will
this
piece
of
work
be
incorporated
into
the
future
version
of
the
model,
so
the
community
will
benefit
from
that
and
yes,
definitely.
This
is
a
really
important
component.
Csm
and
ctsm
and
clm
are
community
models
which
have
been
developed
as
a
partnership
between
incar
and
the
wider
community.
So
this
isn't
just
a
model
that
we
developed
at
ncar.
C
This
is
a
model
that
has
experts
in
many
many
different
fields
throughout,
like
our
wide
community
of
users
and
I'll
put
a
call
out
here,
the
land
and
biogeochemistry
working
groups
which
are
part
of
csm
project
they're
the
key
way
to
be
integrated
into
this
process.
C
So
if
you
come
to
the
meetings,
if
you
work
with,
will
who's-
and
I
perhaps
will
let
you
have
a
shout
out
here-
but
the
importance
of
being
involved
in
the
working
groups
in
terms
of
being
involved
in
the
way
that
the
model
is
going
forward
and
the
key
decisions
that
are
being
made
and
also
incorporating
new
science
I'll.
Let
you
have
something
in
there
if
you
want
well.
E
Sure
yeah
being
involved
in
any
of
the
working
groups.
This
is
true
for
the
land
or
biology
chemistry,
working
groups,
but
also
it's
true
for
any
other
other
model
components,
there's
working
groups
for
all
of
them
and
it
really
helps
us.
It
helps
us
know
what
developments
you're
working
on,
what
science!
Your!
What
science
questions
you
have
if
you
can
be
involved
in
those
working
groups-
and
so
you
know,
one
example
on
the
land
side-
would
be
daniel.
E
To
improving
ctsm
and
by
working
relatively
closely
with
us
at
ncar
daniel
was
successful
in
getting
that
into
the
model
and
now
he's
here
as
a
postdoc.
So
it's
a
good
way.
It's
a
good
way
to
get
involved
and
and
it's
easier
for
everybody,
if
you
kind
of
have
frequent
communication
with
the
working
group
and
and
the
working
group
liaison
and
the
co-chair
and
other
people
that
are
involved
in
this
esm
effort.
C
Yeah
I'll
just
point
out
that
will
is
actually
the
co-chair
one
of
the
co-chairs
for
the
land
model
working
group.
So
if
you,
if
you
wonder
like
he's,
definitely
a
good
person
to
contact
but
awesome
keith
is
still
the
liaison
for
the
land
model
working
group
yep,
so
keith,
keith
olsen's,
also
the
other
person's
key
person
to
talk
to
that
said.
We
have
forums
within
the
csm
within
the
csm
website
that
people
can
post
questions
to
as
well
and
become
more
involved
in
the
community
and
the
way
the
model
is
being
developed.
C
If
you
find
things
that
are
issues
with
the
model,
raising
them
through
the
working
groups
is
really
good
too.
Okay,
next
question:
is
it
possible
to
change
the
pft
in
clm
if
it's
possible?
What
is
the
file
that
have
to
be
changed
and
is
there
a
tool
to
do
it?
So,
yes,
definitely.
This
is
one
of
the
key
things
that
I
work
on
is
looking
at:
describing
land
use
and
land
cover
change
and
how
plant
functional
types
crop
functional
types,
all
the
all.
C
The
different
land
units
such
as
such
as
the
crop
area
or
the
natural
vegetation
area,
change
wood
harvest,
and
we
have
two
files
that
we
that
specify
both
land
cover
and
land
use
and
the
first
one
is
the
initial
surface
data
file,
which
contains
all
the
static
components.
It
tells
you
the
initial
distribution
of
vegetation,
plus
also
things
like
soils
and
soil
color.
C
It
tells
you
all
hydrological
properties,
such
as
slope
and
elevation,
so
those
all
come
into
the
surface
data
file,
and
then
we
have
a
transient
file,
which
basically
is
this
annual
time
series
called
the
land
use,
time
series
file
and
it
updates
plant,
functional
types
and
crop
functional
types
and
the
relative
weights
of
the
crop
versus
natural
vegetation
area.
It
also
does
things
like
prescribes
irrigation
and
fertilizer
wood
harvest
and
all
those
components
are
in
the
land
use
time
series
file.
C
There
are
tools
for
generating
both
of
these
files,
and
this
is
sort
of
a
little
bit
of
the
workflow
that
comes
through.
So
we
have
a
tool
called
the
cm5
land
use
data
tool
which
you
can
contact
me,
but
it's
available
on
github
and
we
have
all
the
data
sets
that
go
into
that
also
stored
on
our
dusk
server.
C
We
then
generate
these.
What
we
call
raw
clm
files,
which
are
the
the
typically
they're
a
quarter
degree
resolution.
We
also
generate
them
at
0.5
degrees
resolution
and
they
go
into
a
tool
called
make
surf
data
and
so
make
surf.
Data
takes
this
transient
time
series
data
plus
all
the
other
raw
data
sets
that
I
was
talking
about.
C
I'm
currently
writing
up
the
tech.
Note
that
goes
with
the
land
use
data
tool
and
also
gives
you
an
idea
about
what
is
going
on
in
terms
of
the
other
raw
data
sets
that
are
going
into
clm,
hopefully
have
that
finished
off
very
soon,
and
that
will
provide
some
background
documentation
for
using
these
tools
as
well.
Okay,
next
question:.
B
C
B
B
Pft
we
currently
have,
I
think,
15,
14
or
15
natural
plant,
functional
types
and
people
in
the
past
have
modified
a
pft
or
added
a
pft
by
by
modifying
the
parameters
associated
with
each
plant
type.
And
so,
if
you
know
what
the
parameter
value
should
be
for
all
the
key
plant
parameters,
you
can
introduce
a
new
pft.
B
B
Maybe
the
tropical
trees,
because
you're
not
going
to
need
to
use
them
adding
a
new
pft
completely
to
get
16
natural,
pfts
or
17
natural
pfts
is
actually
quite
challenging
at
the
moment,
we'd
like
to
make
that
easier,
but
that's
sort
of
the
state
of
the
series
where
we
are.
C
Thanks
dave,
yeah,
that's
exactly
right:
okay,
so
as
a
non-expert
on
land
modelling.
How
well
constrained
of
potential
spurious
feedbacks
of
land
cover
change
in
csm?
If
you
suppose
some
forest
spuriously
disappear
by
2100
models
has
the
effect
on,
for
example,
climate
sensitivity
being
studied,
and
so
yes,
just
getting
back
to
that,
we
definitely
put
land
use
and
land
cover
change
and
we
look
at
a
whole
range
of
different
potential
scenarios
as
well.
C
So
we're
able
to
compare
different
land
cover
trajectories,
so
we
could
look
at
what
would
happen
in
a
world
where
we
did
large-scale
reforestation,
and
so
we
can
see
how
that
would
impact
surface
climate
through
changing
surface
energy
budgets
and
changing
the
hydrological
cycle.
But
we
can
also
see
how
it
impacts
the
carbon
cycle
so
where
the
carbon
is
being
stored
in
wood
products
or
how
soil
carbon
is
changing.
C
C
This
is
prescriptive
ways
of
running
clm
5.,
as
we
spin
up
into
the
fates
model,
which
should
be
available
sometime
soon,
we'll
be
able
to
look
at
being
able
to
see
what
happens
in
terms
of
feedbacks
within
ecosystems
as
well,
so
that
if
a
we
saw
a
large
scale
drying
and
increase
some
fires
in
the
amazon,
we
would
see
what
would
happen
with
the
diet
back
the
amazon
in
terms
of
precipitation,
recycling
and
drought,
locking
and
things
like
that.
C
I
think
that's
the
last
question,
so
I'm
going
to
stop
sharing
there
and
probably
just
open
up
the
open
up
the
floor
for
questions
and
discussion
with
all
of
the
participants
and
so
people.
I
guess
there's
a
lot
of
questions
raised,
there's
raised
hands
and
there's
a
lot
of
questions
in
the
chat,
so
maybe
I'll
just
start
going
through
the
chat
start
with
and
there's
a
lot
of
specific,
and
I
see
people
that
actually
answered
a
lot
of
their
questions.
C
That
sounds
great,
so
if
people
want
to
raise
their
hand-
or
I
think,
that's
probably
a
good
way
of
doing
it,
okay,
genuine
do
you
want
to
unmute
yourself
and
ask
a
question:
maybe
put
your
camera
on
as
well
just
so
we
can,
if
you
want
to,
if
you
don't,
then
it's
fine
too.
A
A
B
B
So
there
is
no,
you
know
automated
way
to
do
this
now,
like
you
just
give
it
a
a
a
data
set
that
could
read
in,
but
you
could
certainly
do
it.
There'd
be
two
ways
one
is
you
could
introduce
a
data
set
with
a
mask
that
you
read
in,
and
you
know
if
you
wanted
to
do
that,
I
think
we
most
likely
would
be
best
if
we
give
you
a
little
bit
of
guidance
on
that,
but.
B
If
you
just
want
to,
you
know,
stop
the
missions
from
a
box,
you
could
go
into
the
code
and
essentially
put
an
if
statement
in
there
and
say
if
it's
within
that
box
turn
off
the
dust
emissions,
and
we
have
done
that
kind
of
thing
in
the
past
so
that
you
know
that
would
work
as
well.
That
would
also
not
be
too
that'd,
be
the
easiest
way
to
do
it
and.
F
B
If
you
have
any
problems
with
that,
we
could
we
could
help,
but
there's
nothing
like
saying
you
know
just
like
a
switch
or
something
like
that
currently
in
the
model
to
turn
off
in
a
region.
A
B
There
is
a
just
a
rotability
file
and
another
possible
way
is
to
go
in
and
modify
that
dust
or
ability
file
to
make.
I
don't
know
what
the
value
would
be
to
make
it
extremely,
not
erodible
like
a
really
big
or
really
small
number.
I
don't
know
which
way
the
numbers
go,
that
that's
another
alternative
that
might
work
that
would
be
actually
would
not
require
you
to
modify
the
code.
B
I've
never
really
played
with
that
file
at
all.
So
I
don't
know
you
know
what
it
looks
like,
but
that
would
be
another
another
potential
avenue
in
fact
now
that
I
think
about
it.
That
might
be
the
best.
The
best
option
just
and.
C
Right,
if
we
don't
have
any
other
questions,
katie
and
keith-
I
don't
know
if
you
want
to
like,
have
anything
about
the
questions
that
have
been
raised
through
and
okay.
You've
done
a
lot
of
work
in
terms
of
the
parameter,
uncertainty
and
understanding
how
we
go
about
using
large-scale
perturbation
studies.
Do
you
want
to
maybe
like
just
have
a
little
bit
of
a
statement
about
the
work
you're
doing
with
that.
D
Sure
yeah,
I'm
glad
this
was
kind
of
already
covered
in
a
question
about
uncertainty,
but
there's
lots
of
different
sources
of
uncertainty
in
our
model
projections.
So
peter
mentioned
looking
at
different
cmip
scenarios.
So
that's
kind
of
thinking
about
forcing
uncertainty
and
how
we
don't
know
the
exact
carbon
emissions
pathway.
D
That
particular
example
probably
includes
both
structural
and
parametric
uncertainty,
because
we've
made
changes
both
to
the
actual
physical
equations
that
are
used
in
the
model
and
the
parameters,
and
so
the
third
source
of
uncertainty
is
the
parametric
uncertainty
and
that's
what
daniel
alluded
to
at
the
beginning.
When
we
were
talking
about
the
parameter,
perturbation
experiments
that
we're
doing,
and
so
by
kind
of
sampling
across
what
we
think
are
different
reasonable
parameter
values
in
clm,
and
there
are
a
lot
and
it's
a
very
you
know,
sort
of
uncertain
and
big
space.
D
C
Katie
and
keith,
we
talked
about
land
use
and
land
cover
change,
but
we
didn't
really
talk
about
the
urban
model,
which
I
have
seen
a
lot
of
interest
on
the
csm
forums
and-
and
I
think
that's
a
really
important
area-
do
you
want
to
have
a
little
bit
of
a
spiel
about
the
the
urban
model
and
how
we
try
and
represent
different
ways.
Humans
change,
the
landscape.
From
that
perspective,.
F
Yeah
sure
so
we
have
we
have.
F
We
represent
urban
land
units
with
the
urban
canyon
model
kind
of
consists
of
roads,
walls
and
then
a
roof,
and
we
have
the
capability
of
having
up
to
three
different
types
of
those
urban
land
units
in
a
grid,
cell
kind
of
categorized
by
density,
tall
building,
district
and
high
density,
and
then
medium
density
and
those
differ
in
terms
of
their
kind
of
basic
properties
such
as
the
building
heights
and
surface
characteristics
such
as
albedo
and
thermal
conductivity,
and
that
kind
of
thing
like
different
different
wall
types
and
different
roof
types,
etc.
F
Currently,
I'll
say
that
the
urban
urban
land
units
are
static,
so
they're
they're
kind
of
fixed
at
present
day.
So
there's
no
urban
lane
units
don't
change
over
time.
They
don't
expand
or
contract
over
time.
But
we
have
a
project
lais
out
at
the
university
of
illinois,
who
is
working
on
developing
data,
sets
to
change
urban
land
units
over
time
and
try
to
incorporate
those
into
the
model
and
try
to
understand
the
impacts
of
future
urbanization.
F
C
So
it's
currently
less
than
around
about
half
a
percent
of
the
whole
land
surface
of
the
world
is
represented
by
the
the
urban
model,
but
it
has
a
really
important
component
for
our
understanding
of
impacts
and
our
understanding
of
the
the
the
the
future
climate.
How
people
will
experience
it's
a
really
important
component,
even
though
it's
a
small
fraction
of
the
land
surface
in
terms
of
fluxes
to
the
atmosphere.
F
Right,
I
think
that's
that's
probably
going
to
change
in
the
future.
Some
of
the
urbanization
scenarios
are
quite
quite
impressive
in
terms
of
how
much
urban
areas
going
to
expand
and
and
more
and
more
people
in
the
future
are
going
to
be
living
in
urban
areas.
So
it's
important
to
understand
how
different
the
urban
climate
is
compared
to
the
kind
of
the
climate
we
look
at.
It
was
just
in
the
model
which
is
vegetation,
vegetation,
climate.
C
So
yeah,
no
absolutely
I
just
started
rereading
the
isaac,
asimov
foundation
series
and
the
key
planet
in
that
is
all
urban
there's,
just
nothing
beside
built
environment
in
that.
So
it's
an
interesting
point.
I
see
that
hemorrhage
has
got
his
hand
right.
So
do
you
have
a
question?
I
think
we're
about
to
probably
end
our
time
here
because
we're
at
9
45
so
I'll.
Let
him
rush
have
his
question
and
then
maybe
gustavo
you
can
take
back
over.
A
Yeah,
I'm
looking
for
the
language
time
series,
data
and
soft
data
like
for
the
future,
looking
for
different
ssp
scenarios
and
then
yeah
this.
I
didn't
find
the
urban
scenario
for
the
future,
because
I
was
sending
the
pct
net
pft
and
then
trying
to
change
the
pct
crop
and
pct
cft
like
this.
But
when
I
just
change
the
pct
crop,
then
there
is
an
error
and
like
the
song
is
not
one.
Obviously
there
is
there
will
be
the
error
right.
A
So
I
try
to
change
the
pct
net
vegetation
and
I
was
like
looking
for
the
future
orban
and
future
glaciers
and
many
things
right,
but
I
didn't
find
that
so
did
I
miss
anything
or
like
it
is
not
available.
C
Right,
so
it's
really
interesting
that
you
bring
that
up
so
like
with,
as
kate
said,
with
the
urban
distributions
they're
static
in
the
model
right
now,
but
okay,
we've
got
some
breakout
rooms
about
to
go
so,
but
what
I
was
going
to
say
was
you
can?
Actually,
if
you
could
wanted
to
create
your
own
urban,
you
can
put
it
through,
make
sure
and
enjoy
a
static
new
urban
dataset.
That's
one
way
of
doing
it.
C
The
plant
functional
types
we've
spent
a
lot
of
time,
trying
to
incorporate
ways
so
that
we
always
meet
all
the
criteria,
so
it
always
has
to
add
up
to
100.
You
have
you
can't
have
98
or
even
99.99
it'll
crash
out
the
model.
That's
the
area
you're
talking
about.
C
So
we
have
tools
that
do
high
precision
and
work
out
how
to
do
the
allocation.
I'm
very
happy
to
talk
with
you
offline
on
this
is
probably
the
easiest
way
rather
than
trying
to
force
into
the
last
30
seconds,
but
maybe
we'll
just
leave
it
there.
There
are
tools
that
are
available,
we've
got
github
repositories
for
them,
and
data
sets
to
support
them.
So,
let's,
let's
have
a
talk
offline
on
that
one.
C
Thank
you
to
all
the
panelists
there
was.
It
was
brain
all
your
contributions,
very,
very
valuable.
Thanks
for
all
the
questions
from
all
of
the
participants
in
the
csm
tutorial.
I
hope
this
has
been
give
you
some
insight
into
how
we
do
research
with
the
model
and
who
some
of
the
key
people
who
are
working
and
supporting
the
model.
