Comments

  • This product superseded OSI-302-b on 23 May 2023 at 12:00 UTC. The major changes are the following:

    • Inclusion of VIIRS data from NOAA-20 and S-NPP
    • Inclusion of Metop-C
    • Switch from PPS v2014 to PPS v2021 for cloud products
    • Adjustment of the cloud transmittance coefficient

    The product file format is mainly unchanged, except some additions/corrections to the global attributes. For more details, check the new Product User Manual here:
