Short summary
In this study we present a new processing methodology for retrieving surface elevations and elevation changes over glaciated terrain from CryoSat-2 data. The new methodology has been shown to be less sensitive to changes in near-surface dielectric properties and provides improved elevation and elevation change retrievals. This methodology has been applied to the Greenland Ice Sheet to provide an updated volume change estimate for the period of 2011 to 2015.
