Satellite radar altimetry operating at Ku-band has provided crucial observations of ice sheet elevation change for more than three decades, offering a direct means to assess climate impacts. Surface h...

Abstract. The EU and ESA plan to launch a dual-frequency Ku- and Ka-band polar-orbiting synthetic aperture radar (SAR) altimeter, the Copernicus Polar Ice and Snow Topography Altimeter (CRISTAL), by 2...

Abstract. The recent alignment of CryoSat-2 to maximise orbital coincidence with the Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) over the Southern Ocean and Antarctica in July 2022, known as...

Climate and ice sheet processes in Antarctica increasingly reflect those observed earlier in Greenland. Applying process insights from Greenland can improve projections of future Antarctic ice and climate behaviour.

Abstract. Sea ice altimetry currently remains the primary method for estimating sea ice thickness from space, however time-series of sea ice thickness estimates are of limited use without having been ...

2nd International Review Workshop on Satellite Altimetry Cal/Val & Metrology The 2nd International Review on Satellite Altimetry Calibration/Validation (Cal/Val) and Metrology is to be held in Chania,...

In the Cryosphere Research Group at DTU Space, we monitor the recent and ongoing changes of the ice-covered regions of the Earth, including ice sheets and sea ice, using observations from satellites, aircraft and ground. During the past decades, satellites have observed a decline in sea ice and an increased mass loss of the Greenland ice sheet. Our research leads to an increasingly accurate understanding of these rapid changes, thus enabling society to mitigate climate change.
