Daily weather grids from old soundings (NOAA-10)
What it measures. Daily weather grids covering the globe at 1-degree detail, with atmospheric parameters worked out from old satellite sounding instruments.
How it's made. Derived from HIRS/2 and MSU radiance measurements on the NOAA-10 satellite using a French retrieval method, then averaged over each day and mapped onto a 1-by-1-degree grid as part of NASA's TOVS Pathfinder project.
How & where you'd use it. Provides a historical record of atmospheric conditions useful for long-term climate and weather research drawing on early satellite-era observations.

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-10 satellite.
