ASCAT-ERA5 Antarctic Peninsula Daily Surface Meltwater Production (2007-2022)

  • 1. Pennsylvania State University


Estimates of daily surface meltwater production across the Antarctic Peninsula over 2007-2022 at 4.45-km spatial resolution. These data were generated using a random forest model combining enhanced resolution ASCAT C-Band radar backscatter, ASCAT-detected surface melt presence (, and ERA5 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 ice shelf automated weather stations (Jakobs et al., 2020), before scaling up to the Antarctic Peninsula region using ERA5.   

This record will be updated upon publication of a forthcoming manuscript.
