This paper demonstrates an inversion of surface CO 2 fluxes using concentrations derived from assimilation of satellite radiances. Radiances come from the Atmospheric Infrared Sounder (AIRS) and are assimilated within the system of the European Centre for Medium‐Range Weather Forecasts. We evaluate the quality of the inverted fluxes by comparing simulated concentrations with independent airborne measurements. As a benchmark we use an inversion based on surface flask measurements and another using only the global concentration trend. We show that the AIRS‐based inversion is able to improve the match to the independent data compared to the prior estimate but that it usually performs worse than either the flask‐based or trend‐based inversion.
