The project aims to develop and validate different approaches to retrieve snow thickness over the sea ice; to develop a new prototype processor; and to produce and validate an experimental dataset of snow thickness over the Arctic.
The project focuses on implementing a high-resolution quasi real-time snow monitoring to improve water resource management. It is taking advantage of the recent developments in physically-based snow modelling and is based on high-resolution optical and radar EO missions such as Sentinel-1 and 2. The core service is a snow water equivalent (SWE) product generated using …

Lakes that form a seasonal ice cover are a major component of the terrestrial landscape. They cover approximately 2% of the Earth’s land surface, with the majority of them located in the Northern Hemisphere. The presence (or absence) of ice cover on lakes during the winter months affects both regional climate and weather events, such …
Accurate estimates of sea ice thickness are essential for numerical weather prediction, ice extent forecasts for navigability and to demonstrate the impacts of climate change on sea ice. The main source of uncertainty in sea ice thickness measurements from radar altimetry is due to snow. Scattering of the radar signal as it travels through snow …
Using CryoSat-2 interferometric synthetic aperture radar (SARIn) altimetry together with NASA’s operation IceBridge and IceSat-2 Lidar data in a multi-layer neural network (NN) in order to enhance CryoSat-2 SARIn swath measurements. Further investigation will be carried out into the use of these corrections to derive surface condition state and change. The European Space Agency (ESA), …
The Arctic is a complex region encompassing different physical and biogeochemical processes and interactions among several components of the Earth system (e.g., sea ice, ocean, glaciers, ice caps, the Greenland Ice Sheet, snow, lakes and river ice, permafrost, vegetation, complex interactions with the atmosphere, people, etc.). Changes in the Arctic have a strong impact on …

This project will use various InSAR based approaches to characterize changes in land subsidence rates due to permafrost melting in Greenland and assess the impact such changes are having on critical infrastructure in the region.
Why has Antarctic sea ice experienced a small increase in extent over the past decades in stark contrast to the rapid decline observed in the Arctic? What role are the Southern Ocean and sea ice playing in controlling the Deep Water formation and thermohaline circulation and the melting of the Antarctic ice shelves and sea …
