AB: Carbon monoxide CO is a key component of the troposphere. It is the principal sink of hydroxyl radicals OH in the free troposphere (CO global mean lifetime is about 2 months) and thus it controls indirectly the lifetime of many other species, such as methane CH4. In the presence of nitrogen oxides, NOx ($>10-15$ pptv), and sunlight, CO is a precursor of tropospheric ozone O3. The processes leading to the emission of CO are fairly well established. CO is a byproduct of fossil fuel use and incomplete biomass combustion. The incomplete oxidation of hydrocarbons also produces substantial amounts of CO. Uncertainties attached to CO sources are still high and, as a result, the comparison of model results and observations can show large discrepancies. These discrepancies are used to optimize the monthly sources of CO over large regions for the period April 2000 to March 2001.
