Carbon monoxide in the air (MOPITT, near + thermal infrared)

MOPITT Beta Derived CO (Near and Thermal Infrared Radiances) V109
atmosphere NASA LARC_CLOUD Level 2 HDF-EOS5
In plain English

What it measures. Amounts of carbon monoxide in the lower atmosphere, given both as vertical profiles (how much at different heights) and as a total amount in the air column, along with notes on surface and cloud conditions and an error estimate for each value.

How it's made. Derived from the MOPITT instrument on the Terra satellite, which combines near-infrared and thermal-infrared measurements; this is an early beta release that may be recalibrated.

How & where you'd use it. Useful for tracking air pollution and how carbon monoxide moves through the atmosphere, though as a beta product it is best treated as preliminary rather than final.

Official description

MOP02J_109 is the Measurements Of Pollution In The Troposphere (MOPITT) Beta Derived Carbon Monoxide (CO) (Near and Thermal Infrared Radiances) version 109 product. It consists of the geo-located, retrieved carbon monoxide profiles and total column amounts for carbon monoxide. Ancillary data concerning surface properties and cloud conditions at the locations of the retrieved parameters are also included. An estimated error accompanies each retrieval. Version 109 products are beta versions of version 9 products; they are unvalidated beta products subject to recalibration. Data collection for this product is ongoing. 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.
