These annual mosaics of ice velocity are generated from Sentinel-1 synthetic aperture radar (SAR) interferometric wide (IW) mode data. Measurements which are input these annual mosaics were generated using the intensity feature tracking method implemented with the GAMMA Remote Sensing software package. Georeferencing was completed within this processing chain using the NSIDC 1km Antarctic DEM (https://doi.org/10.5067/H0FQ1KL9NEKM) and the Reference Elevation Model of Antarctica version 1 (https://doi.org/10.5194/tc-13-665-2019). Annual mosaics are the mean of all available tracking results.
