This site provides information and data from the MAPS experiment, a NASA program measuring via satellite the global distribution of carbon monoxide in the free troposphere. This site offers detailed accounts of mission objectives, operations, current status, and results, including color maps indicating global distribution of carbon monoxide. A project overview details the mechanism of the MAPS instrument hardware and some of the scientific principles behind its detection. The current flight of the MAPS experiment is taking measurements to evaluate seasonal changes in carbon monoxide sources and chemistry.
