Data from Cryosat-2 satellite showing elevation change over Pine Island Glacier and Thwaites Glacier

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).
