Digital Elevation Models of Thwaites Glacier main trunk (2011-2022)

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.

Statement
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.
