18 cze 2024 · Ice Sheets Today offers the latest satellite data and scientific analyses on surface melting of the Greenland Ice Sheet in the Northern Hemisphere and Antarctic Ice Sheet in the Southern Hemisphere. Surface melt on each ice sheet results from a combination of daily weather conditions and the amount of solar energy absorbed by its snow and ice.

During September 2022, the Greenland Ice Sheet experienced unprecedented late-season melt events, including surface melt conditions across 36% of the ice sheet surface on 3 September, including at Summit Station (3216 m above sea level in the ice sheet interior).
In addition to generating daily maps and graphs of surface melt data, Ice Sheets Today provides the following data tools with a focus on the Greenland Ice Sheet. Greenland Surface Melt Extent Interactive Chart. Explore the interactive graph below and look at Greenland surface melt extent over time.
Currently, the total accumulation of ice on the surface of Greenland ice sheet is larger than either outlet glacier losses individually or surface melting during the summer, and it is the combination of both which causes net annual loss.
Ice sheets gain mass from net snow accumulation and lose mass through meltwater runoff and solid ice discharge. The sum of accumulation and runoff is termed surface mass balance (SMB) and is primarily responsive to air temperature, snow cover, albedo, and bare-ice area.
17 sty 2024 · We found that Greenland has lost more than 1,000 gigatonnes (1 Gt is 10 9 tonnes) of ice owing to terminus retreat alone since 1985 (Fig. 1), representing an extra 20% loss that has not been ...
18 paź 2023 · Greenland holds enough ice to raise global sea levels by 7 metres if it were all to melt. The sheet currently loses around 270 billion tonnes of ice each year, and contributes a substantial...
