4D-Var data assimilation system for estimating upper troposphere CO2 columns from AIRS instrument

The operational 4D-Var data assimilation system of the ECMWF has been adapted and applied to estimate the upper troposphere CO2 concentration from the infrared radiances determined by the AIRS instrument (Engelen et al., 2004, Engelen and McNally, 2005). As an interesting side effect the concurrent CO2 retrieval together with other meteorological variables also improves the weather model forecast.
