Ice Sheets Today - National Snow and Ice Data Center
2025年1月8日 · 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.

The Greenland Ice Sheet lost 55 ± 35 Gt of mass in 2024, the lowest annual ice loss since 2013. This occurred due to above-average snowfall and below-average melting and despite higher glacier flow rates than the 1991-2020 average.
Greenland Ice Sheet melt season starts | National Snow and ...
2024年6月18日 · On April 25, 2024, a moderately strong melt event kicked things off early on the Greenland Ice Sheet. Since then, however, the melt season has been fairly typical. Snowfall in early June blanketed exposed ice, which will slow the onset of more intense melting and run off for the next few weeks.
