Part 2: an overview with the atmospheric mesoscale transport model CHIMERE, A B S T R A C T In this issue, Ramonet et al. revealed a positive trend in European, atmospheric CO 2 concentrations relative to a marine, North Atlantic reference baseline, for the years 2001-2006. The observed build up mainly occurred during the cold season where it reaches a 0.8 ppm yr −1 at low-altitude stations to a 0.3 ppm yr −1 at mid-altitude stations. We explore the cause of this build-up using the mesoscale model CHIMERE. We first model the observed trends, using interannually varying fluxes and transport, then suppress the interannual variability in fluxes or aspects of transport to elucidate the cause. The run with no interannual variability in fluxes still matches observed trends suggesting that transport is the major cause. Separate runs varying either boundary layer height or winds show that changes in boundary layer height explain the trends at low-altitude stations within the continents while changes in wind regimes drive changes elsewhere.
