*Preliminary data associated with manuscript submission to The Cryosphere* Gridded estimates of Antarctic sea ice physical properties derived from CryoSat-2 Baseline-D SAR and SARIn data spanning July 2010 through August 2021. Data are generated using the CryoSat-2 Waveform-Fitting method for Antarctic sea ice (CS2WFA). Files include: CS2WFA_25km_YYYYMM.nc: Monthly meanvalues gridded on the NSIDC25km polar stereographic grid. Each file represents 1 month of data (134 files total). Each monthly file contains: latitude, longitude, and time (in months since January 2000) Grids of retrieved snow depth, snow freeboard, ice freeboard, and sea ice concentration Grids of seasonal snow, sea ice, and seawater density Grids of sea ice thickness andestimated thickness uncertainty, as well as thickness estimated using a 70% threshold retracker and using a zero-ice-freeboard assumption.
