We extended two sea-ice concentration data sets: the IFREMER-ICDC ASI-algorithm sea-ice concentration data set until 2024-07-31; this data set comes at 12.5 km grid resolution on a polarstereographic grid and begins 1991-12-05:

Sea-Ice concentration for Arctic & Antarctic (ASI-SSMI)

and the EUMETSAT OSI SAF OSI-450a / OSI-430 sea ice concentration climate data record (CDR) until 2024-06-30; this data set comes at 25 km grid resolution on an EASE2.0 grid and begins in November 1978:
