This dataset consists of grids of dh/dt computed over 3-year periods as well as annual grids of average dh and their corresponding uncertainties covering the period 1992 to 2019 using satellite radar altimetry data from ERS-1/2, ENVISAT and CryoSat-2 over the Amundsen Sea Embayment. This dataset has been prepared for the publication 'Amundsen Sea Embayment ice-sheet mass-loss predictions to 2050 calibrated using observations of velocity and elevation change' by Bevan et al. (2023, accepted), Journal of Glaciology. The methods used for the derivation of this dataset are described in Shepherd et al, Trends in Antarctic ice sheet elevation and mass, 2019, GRL vol 46 issue 14 pp 8174-8183, https://doi.org/10.1029/2019GL082182.
