This dataset (provided as a series of CF-compatible netcdf file) consists of 5 maps of Antarctic landfast sea ice, derived from NASA MODIS imagery. There is one map per year, spanning the 5 year period from 2018 to 2022. The one map per year covers the time period from Day-Of-Year 61-75, which is the time of yearly minimum extent. The data are provided in a polar stereographic projection with a latitude of true scale at 70 S (i.e., to maintain compatibility with the NSIDC polar stereographic projection).
