Entry ID: MOP03T_109

Tropospheric Composition

Description

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, 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 for version 9 products, they are unvalidated beta products subject to recalibration. V9 is an improvement over V8 because of several scientific enhancements. These include: A revision of the cloud filter to allow through a much higher number of pixels that were previously considered cloudy, a minor correction to the Forward Model to account for long-term drift of the pressure in the gas cell, and a careful analysis of the NIR calibration process which reduces discontinuities associated with calibration events. 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 quality and the limitations of the retrievals. [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.
