Assimilation of the 2000-2001 CO MOPITT retrievals with optimized surface emissions -: art. no. L20105

The multi-year retrievals of carbon monoxide ( CO) by the MOPITT ( Measurements Of Pollution In The Troposphere) instrument onboard the NASA Terra satellite provide an opportunity for the first time to study quantitatively the transport and sources of pollution in the mid-troposphere. This paper presents the assimilation of the Phase I ( March 3, 2000 - May 6, 2001) MOPITT retrievals with optimized CO emissions constrained by monthly MOPITT CO data. The observed-minus-forecast (OmF) CO distributions illustrate improvement of this data analysis compared with the assimilation that employs climatological surface fluxes.
