Abstract

An inverse model using atmospheric CO2 observations from a European network of stations to reconstruct daily CO2 fluxes and their uncertainties over Europe at 40 km resolution has been developed within a Bayesian framework. In this first part, a pseudo-data experiment is performed to assess the potential of continuous measurements over Europe using a network of 10 stations of the AEROCARB project such as in 2001 (http://www.aerocarb.cnrs- gif.fr).Under the assumptions of a small observation noise and a perfect atmospheric transport model, the reconstruction of daily CO2 fluxes and in particular of their synoptic variability is best over Western Europe where the network is the densest.
