We extended the IFREMER-ICDC ASI-algorithm sea-ice concentration data set until 2023-06-30; this data set comes at 12.5 km grid resolution and begins 1991-12-05:
Sea-Ice concentration for Arctic & Antarctic (ASI-SSMI)
We also extended the Reynolds - OISST sea surface temperature (SST) data set until 2023-06-30; this data set comes at 0.25 degree grid resolution and is offered at daily and monthly temporal resolution - including anomalies with respect to 1982-2001 and 1992-2011:
