Seasonal evolution of basal conditions within Russell sector, West Greenland, inverted from satellite observations of surface flow
An annual set of model-inferred basal and surface properties of ice flow at Russell Gletcher sector in Western Greenland with half-month temporal resolution. Derived using the Elmer/Ice ice-flow model by inversion of satellite-observed ice surface velocity (10.5281/zenodo.5535532). The details on th...
