NEW NERC PROJECT International Collaboration on Data Assimilation in Terrestrial Carbon Cycle Science Exchange between scientific staff for three months from key institutions (CSIRO, MPI, LSCE, CSU, MBL; in the UK, CTCD and DARC are joint leaders on this project, but we will also be looking at the needs and opportunities for QUEST, ECMWF, CLASSIC and CEH). International conference Six international workshops

Structure of Carbon Theme Ocean surface observations Atmospheric observations of CO 2 and CH 4 Land surface observations Data assimilation Ocean surface Flux model Model parameters Atmospheric chemistry-transport model Land surface flux model Model parameters Surface fluxes

C Cycle Sub-themes  Using atmospheric measurements of CO2 and CH4 to learn about surface fluxes and their causes.  Model-data fusion for land C fluxes using surface observations  Carbon fluxes from biomass burning  Ground-based methods: data, parameters, process descriptions and EO fundamentals.  Understanding the tropical carbon balance of the land surface.  Quantification of sea surface processes  Quantification of ocean biogeochemistry and carbon fluxes  Quantification of bio-physical interactions and air-sea CO2 fluxes  Data assimilation techniques for marine ecosystem models.  Reanalysis, validation and prediction of marine carbon estimates
