Daily carbon monoxide maps (MOPITT, thermal infrared)

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

What it measures. Daily averaged amounts of carbon monoxide in the lower atmosphere, both as vertical profiles and as total column amounts, arranged onto a map grid.

How it's made. Derived from the MOPITT instrument on Terra using its thermal-infrared channels, then averaged from the underlying per-orbit measurements into daily gridded maps.

How & where you'd use it. Handy for making daily pollution maps and studying where carbon monoxide builds up and travels, since the gridded daily form is easier to work with than individual orbit files.

Official description

MOP03T_9 is the Measurements Of Pollution In The Troposphere (MOPITT) Carbon Monoxide (CO) gridded daily means (Thermal Infrared Radiances) version 9 data product. The "T" refers to the use of the Thermal (T) 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.
