Using deep learning with CryoSat radar altimetry to adjust elevations and map SURFace penetration  (CryoSURF)

Prime company: UNIVERSITY OF EDINBURGH (GB)

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), …

Systematic swath elevation and monthly DEMs over the Greenland Ice Sheet margin from CryoSat

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 …

Greenland and Antarctica losing ice six times faster than expected

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 …

CryoSat maps ice shelf on the move

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 …

Greenland ice loss much faster than expected

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 …

Deep below Antarctica with GOCE

  A paper, published recently in the Journal of Geophysical Research: Solid Earth, describes how scientists used gravity data from the GOCE satellite mission along with seismological models to reveal unprecedented insight into the crust and upper mantle, otherwise known as the lithosphere, below this frozen continent. Read the full story and find out about …

Prime company: NORCE Norwegian Research Centre AS (NO)

Despite considerable research progress in understanding the polar region over the last decades, many gaps remain in observational capabilities and scientific knowledge. These gaps limit present ability to understand and interpret on-going processes, prediction capabilities and forecasting in the Arctic region, thereby hampering evidence-based decision-making. Addressing these gaps represents a key priority in order to …

Polar Exploitation Platform (P-TEP)

The P-TEP provides a complete working environment where users can access algorithms and data remotely, providing computing resources and tools that they might not otherwise have, avoiding the need to download and manage large volumes of data. This new approach removes the need to transfer large Earth Observation data sets around the world, while increasing the analytical power available to …

A collaboration on Polar science just kicked-off

Polar regions are undergoing major and drastic changes with significant impact at global scale. Addressing this unique set of global challenges will require more than ever that scientists advance their understanding of the different drivers governing changes in Polar regions, its associated processes and its potential impacts and translate that knowledge into solutions for society, …
