Description

MOP03NM_9 is the Measurements Of Pollution In The Troposphere (MOPITT) Carbon Monoxide (CO) gridded monthly means (Near Infrared Radiances) version 9 data product. It contains monthly mean gridded versions of the daily Level 2 CO profile and total column retrievals. For this data product, the averaging kernels associated with each retrieval are also gridded and included in the Level 3 files. 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. 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. 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 product is ongoing.
