Carbon Monoxide

DESCRIPTION

Carbon monoxide (CO) is an important atmospheric trace gas for our understanding of tropospheric chemistry. In certain urban areas, it is a major atmospheric pollutant. Main sources of CO are combustion of fossil fuels, biomass burning, and atmospheric oxidation of methane and other hydrocarbons. Whereas fossil fuel combustion is the main source of CO at Northern mid-latitudes, the oxidation of isoprenes and biomass burning play an important role in the tropics.TROPOMI observes the CO global abundance exploiting clear-sky and cloudy-sky Earth radiance measurements. In the 2.3 µm spectral range of the shortwave infrared (SWIR) part of the solar spectrum, TROPOMI clear sky observations provide CO total columns with sensitivity to the tropospheric boundary layer. For cloudy atmospheres, the column sensitivity changes according to the light path. MOPITT data (as shown below) will be used as part of the verification of TROPOMI CO amounts.
