To assemble all information on land-biosphere processes provided by WPs
1 to 3 into a common framework, to ultimately enable carbon source and
sink estimates at global terrestrial surfaces at a spatial resolution
that satisfies the requirements of a carbon reporting system in support
of the Kyoto Protocol.
Extract and format relevant data to drive improved TEMs (from WP2)
offline from 1990 onwards using meteorological operational analyses.
Carry out high-resolution TEM simulations of the European land carbon
sink using the operational analyses plus remote sensing products (eg:
Develop inverse models for the TEMs and ATM and use these within an
offline Carbon Cycle Data Assimilation System (CCDAS), to adjust both
TEM parameters and prior estimates of carbon fluxes based on a 20-25
year simulation period.
Begin online implementation of the CCDAS in a high-resolution
atmospheric General Circulation Model (AGCM). Make use of the
existing data assimilation structure in the AGCM plus the TEM inverse
model to nudge internal model variables such as respiring soil carbon
and leaf nitrogen based on the atmospheric measurements.
Carry-out a prototype online CCDAS experiment to infer the European
carbon balance from 1990 onwards.
