Daily atmosphere temperature grids (old NOAA-12)

TOVS LMD DAILY GRIDS from NOAA-12 V01 (TOVSBDND) at GES DISC
atmosphere NASA GES_DISC Level 3
In plain English

What it measures. Daily maps of atmospheric conditions, especially temperature, derived from older infrared and microwave sounder readings and laid out on a 1-degree grid.

How it's made. Produced from the HIRS/2 and MSU instruments on the NOAA-12 satellite using a retrieval method developed in France, averaged over each day, as part of a NASA effort to build long-term records from older satellites.

How & where you'd use it. Serves as a historical record of atmospheric temperature for studying past weather and climate.

Official description

Level 3 parameters from HIRS/2 and MSU radiances using the Improved Initialization Inversion (3I) classification retrieval scheme by the Laboratoire de Meteorologie Dynamique (Ecole Polytechnique) averaged over 1 day and mapped on to a 1x1 degree grid. This data was run as part of the NASA TOVS Pathfinder project and designated as Path-B. This dataset contains data from the NOAA-12 satellite.
