MOPITT produces two major data products, one for each of the gases that it monitors:
Methane (CH4): Total vertical column amounts in cloud-free conditions at a spatial resolution of about 22 km x 22 km. The methane channels are only active during daylight, thus no information is returned at night. The measurement accuracy is estimated to be about 1% after validation.
Carbon monoxide (CO): Profiles in cloud-free conditions at a spatial resolution of about 22 km x 22 km horizontally and an approximate equivalent vertical resolution of 3-5 km. During daylight, reliable information is obtained down to the surface. After dark, the information near the surface becomes less reliable. CO soundings are retrieved with 10% accuracy provided by three independent pieces of information, and represented by values on 7 pressure levels between 0 and 14 km.
Scientific studies will employ these data to derive three-dimensional global maps as part of an effort to model global troposheric chemistry.
