CryoSat-2 freeboards from the ESA standard algorithm were combined with ICESat-2 freeboards to derive LaRA snow depths over the Arctic Ocean. Monthly mean LaRA snow depths covering winter months (November through April) were averaged over five winters spanning 2018-2023 to create 5-year snow depth means for each winter month. CryoSat-2 Baseline-E L1A/L2 and ICESat-2 ATL07/10 release 6 data were used in development. Sea ice concentration data from the National Snow and Ice Data Center (NSIDC) and sea surface type data from OSI SAF were used as ancillary data.
