Comments
  • From 19/01/2021, processed with a new chain: improved SST methodology, especially the bias correction parameterization, using cloud mask from NWC SAF software v2018

  • Replaced OSI-206 based on Meteosat-10 input on 20 February 2018

  • Using cloud mask from NWC SAF software v2016

  • This product format is compliant with the Data Specification (GDS) version 2 from the Group for High Resolution Sea Surface Temperatures (GHRSST).
