Comments

  • This product superseded OSI-302.
    Main differences with OSI-302 are:
    • the algorithm improvement, including over sea ice: new cloud type product from PPS v2014 (instead of v2009) and improved surface coefficients,
    • processing on swath data instead of fixed tiles,
    • the new output format (DLI and SSI combined in NetCDF4).
    At the beginning of 2020, the data used are the AVHRR data from Metop-A, Metop-B and NOAA-19.
