NERC EDS UK Polar Data Centre. https://doi.org/10.5285/24aef4f2-3bfc-4014-88e8-34644fdc71a3 This dataset consists of Digital Elevation Models (DEMs) of the surface elevation of Thwaites Glacier. The region covered includes the floating area of the fast-flowing main trunk of Thwaites Glacier, sometimes referred to as Thwaites West Ice Tongue. The DEMs are derived from TanDEM-X SAR data. There are 172 individual scenes that reveal the geometric evolution of this area between 2011 and 2022. This work was supported by the NERC project CALISMO NE/P011365/1.

The processing is fully described in Bevan et al., 2021 (10.5194/tc-15-3317-2021). The data are provided on a Antarctic Polar stereographic grid (EPSG: 3031) as TIFF files. Data collection: TanDEM-X satellite system. Gamma Remote Sensing software. Data quality: Via comparison with ICESat-2 data and in consideration of orbit uncertainty, the original DEMs have an estimated vertical uncertainty of +/-3 m. This is fully documented in the accompanying paper. asNeeded completed
