MOPITT Beta CO gridded daily means (Thermal Infrared Radiances) V109

MOP03T_109 is the Measurements Of Pollution In The Troposphere (MOPITT) Beta CO gridded daily means (Thermal Infrared Radiances) version 109 product. It is an unvalidated beta product subject to recalibration and contains daily mean-gridded versions of the daily Level 2 CO profile and total column retrievals. The averaging kernels associated with each retrieval are also gridded and included in the Level 3 files. Version 109 products are beta versions of version 9 products; they are unvalidated beta products subject to recalibration. Data collection for this version is ongoing.

For a description of the file contents, refer to the File Spec Document. The MOPITT Level 2 Data Quality Statement contains additional information about the retrievals' quality and limitations. [From the MOPITT version 3 Level 3 Data Quality Summary] 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.
