Detailed history :

The product series is operational since 2014:

  • version OSI-208 (Metop-A) from 2014 to 23/02/2016
  • version OSI-208-b (Metop-B) from 23/02/2016 onwards

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.
