Melt pond volumes based on the threshold-based method for lake detection/volume of Moussavi et al., 2020, to 19213 Sentinel-1 Level-1C top-of-atmosphere reflectance granules with less than 30% cloud cover and solar elevation angles above 25 degrees over all Antarctic ice shelves and the surrounding ice sheet. Each granule is processed in the Google Earth Engine at 100 m resampled resolution and converted into lake presence and lake depth. The depth observations were subsequently converted into total accumulated meltwater volumes per lake (in meter water equivalent) by integrating the derived lake depths per pixel over all granules. The resulting melt pond volume dataset (this repository) is then aggregated on the 27 km RACMO2.3p2 grid, accumulating the melt ponds that fall within one model grid cell. Original lake volumes per pixel are available through https://code.earthengine.google.com/?asset=projects/ee-earthmapps/assets/S2_LakesAntarctica_v3
