We have extended the data set of the NSIDC daily gridded sea-ice motion, version 4.1, together with the additional monthly mean gridded sea-ice motion fields derived in-house by one year. These data sets are available at 25 km grid resolution from 11/1978 through 12/2020 for both hemispheres:
Sea-Ice drift vectors for Arctic & Antarctic (NSIDC), v4.1
Connected to that we have extended the NSIDC Arctic Ocean weekly sea-ice age version 4.1 data set by one year. This data set is available at 12.5 km grid resolution for the period 01/1984 through 12/2020:
