MOP02N_9 is the Measurements Of Pollution In The Troposphere (MOPITT) Derived carbon monoxide (CO) (Near Infrared Radiances) version 9 dataset. The "N" refers to the use of the NIR (N) channels in the retrieval. It consists of geo-located, retrieved CO profiles and total column amounts for CO. Ancillary data concerning surface properties and cloud conditions at the locations of the retrieved parameters are also included. An estimated error accompanies each retrieval. 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.
