Comments
  • Updated on 20/06/2017 following L2Pcore product update : greater yield of useful retrievals (essentially of quality class 3) are now available at mid and high latitudes + two extra experimental fields : dust cloud index, "obs minus calc" (OmC) which is used to stratify the quality of the L2P SST retrievals.

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