Langley ASDC -- MOPITT Data Sets

Measurements Of Pollution In The Troposphere (MOPITT) was successfully launched into sun-synchronous polar orbit aboard Terra, NASA's first Earth Observing System spacecraft on December 18, 1999. The MOPITT instrument was constructed by a consortium of Canadian companies and funded by the Space Science Division of the Canadian Space Agency.

MOPITT generates atmospheric profiles of CO using thermal radiation at 4.7 µm. Column carbon monoxide and methane are measured using channels at 2.4 and 2.3 µm, respectively, to sense solar radiation from the surface. However, there are no plans to release a methane data product.
