An improved Antarctic dataset for high resolution numerical ice sheet models (ALBMAP v1)
The dataset described in this paper (ALBMAP)has been created for the purposes of high-resolution numerical ice sheet modelling of the Antarctic Ice Sheet. It brings together data on the ice sheet configuration (e.g. ice surface and ice thickness) and boundary conditions, such as the surface air temp...
