Version 2 of the EUMETSAT OSI SAF and ESA CCI sea-ice concentration climate data records
We introduce the OSI-450, the SICCI-25km and the SICCI-50km climate datarecords of gridded global sea-ice concentration. These three records arederived from passive microwave satellite data and offer three distinct advantages compared to existing records: first, all three records provide quantitativ...
