Datasets used to condition inversions of shear stress at the ice-bed interface on Thwaites Glacier
Included in this handle are input data used in the inversions described in the paper "The impact of basal roughness on Thwaites Glacier sliding." These include surface elevation, and basal topographies used to construct the meshes that define the computational domain as well as the surface...
