22-Nov-22 - STAR JPSS has produced first light imagery from the recently launched NOAA-21 satellite. The image selected shows the Channel 18 (183 Ghz) Brightness Temperature for the ascending node on November 21-22. ATMS, which is the first NOAA-21 instrument to be activated will be followed by CrIS, VIIRS, and OMPS in the coming month
