Antarctic ice sheet daily surface melt detection from ASCAT (2007-2022)
Description
Antarctic ice sheet-wide surface melt detection using enhanced resolution ASCAT C-band radar scatterometer data. Data are daily temporal resolution spanning 2007-2022 and gridded at 4.45 km. Melt detection approach follows Trusel et al., (2012) with updates to threshold and masking procedures. These data were used as a binary melt presence/absence estimate and a predictor in a machine learning-based estimation of Antarctic Peninsula surface meltwater production (https://zenodo.org/record/7995543).
