Extended Data Fig. 4: CryoSat-2 data coverage and elevation time series.
From: Extensive inland thinning and speed-up of Northeast Greenland Ice Stream
a, Points on the NEGIS (black dots) where time series of the elevation H(t) have been estimated using CryoSat-2 data. b, CryoSat-2 elevations at P1 corrected for topography (black error bars) and a combination of our best-fitting seventh-order polynomial and the annual term (red curve). c, The same as b but at P2. d, CryoSat-2 elevations at P1 corrected for topography and annual signal (black error bars) and the best-fitting seventh-order polynomial at P1 (red curve). e, The same as d but at P2.
