ASCAT-ERA5 and ASCAT-MERRA-2 Antarctic Peninsula Daily Surface Meltwater Production (2007-2022)
Description
Estimates of daily surface meltwater production across the Antarctic Peninsula over 2007-2022. These data were generated using a random forest model combining enhanced resolution ASCAT C-Band radar backscatter, ASCAT-detected surface melt presence (https://zenodo.org/record/7995998), and ERA5 or MERRA-2 reanalysis sensible and latent heat fluxes, downward shortwave and longwave radiation, and 2-m temperature. Initial model training was undertaken using meteorological observations and surface melt estimates from surface energy balance modeling at several Larsen C automated weather stations (Jakobs et al., 2020), before scaling up to the Antarctic Peninsula region using ERA5 or MERRA-2.
This record will be updated upon publication of a forthcoming manuscript.
