MOP02T_9 is the Measurements Of Pollution In The Troposphere (MOPITT) Derived Carbon Monoxide (CO) (Thermal Infrared Radiances) version 9 product. The "T" refers to the use of the Thermal (T) 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. Each retrieval is accompanied by an estimated error. 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.
