Rates of elevation change for 2010-2017 derived from interferometric measurements from Cryosat-2. Elevation change was derived from interferometric measurements from Cryosat-2. ESA L1b waveforms retrieved by the satellite in its SARIn (synthetic aperture radar interferometry) mode were processed following the swath processing approach of Gray et al(2013). The resulting dense set of time-dependent elevation measurements was used to derive elevation changes in a Eulerian framework at a 500 m resolution following the method presented in Wouters et al. (2015).

The data set contains two data tif files corresponding to the PIG (PIG0.5_opt1_vmax10_10_r500_dhdtmax30_sedhdtmax1.5_slopemax10_nyr2_ndy2_npt2_nptc1_tmin2_rmsmax100_coh0._noadcheck_all_combined) and THW (THW0.5_opt1_vmax10_10_r500_dhdtmax15_sedhdtmax3_slopemax10_nyr2_ndy2_npt2_nptc2_tmin2_coh0.7_noadcheck_sep10_17_swath) area respectively.
