Carbon monoxide in the air, daily map (MOPITT)

MOPITT CO gridded daily means (Near and Thermal Infrared Radiances) V009
atmosphere NASA LARC_CLOUD Level 3 HDF-EOS5
In plain English

What it measures. Daily maps of carbon monoxide in the air, a pollutant from burning, showing both how much sits in vertical slices of the atmosphere and the total amount in the whole column above each spot.

How it's made. Made from the MOPITT instrument on Terra by combining its infrared measurements into daily averaged maps, using both near-infrared and heat-sensing channels together for a sharper retrieval.

How & where you'd use it. Useful for tracking air pollution and smoke from wildfires and industry, watching how it spreads across regions, and studying changes in air quality over time.

Official description

MOP03J_9 is the Measurements Of Pollution In The Troposphere (MOPITT) Carbon Monoxide (CO) gridded daily means (Near and Thermal Infrared Radiances) version 9 data product. The "J" refers to the Joint use of the Thermal (T) and NIR (N) channels in the retrieval. It contains daily 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 retrievals' quality and limitations. 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.
