We present a comprehensive
analysis of the recent inter-annual variation of the atmospheric CO2
growth rate, with a special focus on the 2002-2003 period, using a state of the
art atmospheric inversion, process driven model simulations (land and ocean),
and recent biomass burning estimates. The inverse estimates compare favourably well
with the model simulations over North Asia and
indicate a large contribution of the fire anomaly to the total anomaly, for
that region in 2003. Over Europe, the spatial distribution of the inverse and
bottom-up flux anomalies for 2003 have similarities but the time evolution of
the total fluxes still need to be reconciled.
