Dataset
EOCIS: Antarctica Mass Balance, v1.0
Abstract
This dataset contains Rates of Mass Change for the Antarctic Ice Sheet produced within the Earth Observation Climate Information Service (EOCIS) project.
Mass change is provided as a 5x5 km grid over the land ice for the Antarctic Ice Sheet (excluding peripheral ice caps and glaciers) and includes drainage basins (Rignot et al., 2016), delivered as NetCDF files. EOCIS land ice products are generated monthly by CPOM from the satellite radar altimetry record, ERS-1 to CryoSat-2. Future product versions for this dataset will be hosted at the Centre for Polar Observation and Modelling (CPOM).
For future updates to this dataset, see the EOCIS CPOM page in the related documents section.
