The CryoTEMPO-EOLIS (Elevation Over Land Ice from Swath) product, now operationally available at on the CryoSat Dissemination Server, exploits CryoSat’s SARIn mode and the novel Swath processing technique to deliver increased spatial and temporal coverage of time-dependent elevation over land ice, a critical metric for tracking ice mass trends. This is the outcome of a …
A sudden stratospheric warming (SSW) is a large-scale meteorological phenomenon in the winter stratosphere, which involves a rapid rise in the polar temperature by a few tens of kelvins in several days. SSWs are triggered by an injection of stationary planetary waves from the troposphere. These events are rare in the Southern Hemisphere, therefore they …
According to IMBIE (Ice Sheet Mass Balance Inter-comparison Exercise) most recent analyses, Greenland and Antarctica lost 6.4 trillion tonnes of ice between 1992 and 2017 – pushing global sea levels up by 17.8 millimetres, on track with the Intergovernmental Panel on Climate Change’s worst-case climate warming scenario. Read the full story and Nature scientific articles …
Monitoring of the melt season contributes to characterizing the seasonal and interannual climatic variations in Antarctica and is important for assessing the future stability of the ice sheet. Due to its 1.4 GHz frequency, SMOS can penetrate much deeper into the ice compared to other microwave imagers operating at 19 GHz: this implies that joint use …

Accurate measurements of the sea ice area and thickness with the aid of ranging data provided by missions such as CryoSat-2 are crucial for the understanding of the transformations occurring in the Arctic, in light of observed changes in seasonality, increase of winter air temperatures and delays in freeze-up. An important factor in the calculation …
Scientists have developed a novel approach of using CryoSat to generate a unique time series of ice front positions for the Filchner-Ronne ice shelf – the second largest ice shelf in Antarctica. Applying a new method, called ‘elevation edge’, to CryoSat’s data has revealed that the entire Filchner-Ronne ice shelf advanced by more than 800 …
The Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE), an international team of 89 polar scientists led by Andrew Shepherd from the University of Leeds and Erik Ivins at NASA’s Jet Propulsion Laboratory, compared and combined data from 11 satellites – including ESA’s ERS-1, ERS-2, Envisat and CryoSat missions, as well as the EU’s Copernicus Sentinel-1 …
