Hm, clearly coordination between the two (if it really ends up as two)
groups is absolutely essential, otherwise we would look entirely
stupid. The first thing that comes to my mind is that nitrogen would be
emphasizing a component of our overall idea which otherwise would not
receive great attention - hence it could be, perhaps, amalgamated. They
probably see it the other way around: In their problem, climatic
variability comes second in importance. My view on this is that all of
our model intercomparisons have shown that models essentially do crazy
things with interannual variability, simply because nobody ever has
tested them for that in any detail. Esser's model would probably be the
last candidate to use here, since it is "less mechanistic" than any of
the others - in fact, Colin and I seemed to agree to "not necessarily"
include it into this proposal. These are just some thoughts for the
moment.

I just finished a very first, rough draft of our outline, and I attach
it to the end of this message. I have just sent it to Martin Heimann,
but I have still not yet talked to him. I also send this whole thing to
Colin, hoping that he will catch the thread through it without
problems. Gerard Dedieu is the one I want to approach next - Alberte is
already talking to him about this in the context with other things.

Cheers,

Wolfgang

Global, spatially explicit assessment of the interannual
variability in terrestrial carbon storage

VERY FIRST, INCOMPLETE draft for a new research proposal
to be submitted to the European Union
for the second phase of the Third Framework "Environment and
Climate"

Goal

A critical uncertainty in assessments of global change impacts
and feedbacks is the source/sink relationship for carbon
between atmosphere and the terrestrial biosphere, and
particularly its interannual variability. Recent advances in
modelling of atmospheric and biospheric processes, combined
with significant progress in data gathering for climate, CO2
and O2, now allow for a dedicated experiment that is likely to
reduce this uncertainty. Equilibrium approaches to the
simulation of global carbon fluxes are no longer adequate for
this, since empirical studies are showing both a long-term
trend and a significant interannual variability of CO2 fluxes,
which appear to be most strongly driven by climatic impacts on
terrestrial vegetation.
Experimental design

For a time period of several decades, we propose to perform a
simulation of biospheric carbon fluxes using:
