Featured Sea Ice Observation Method: ICESat-2
NASA's Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) carries a laser altimeter scientists use to measure the elevation of ice sheets, glaciers, sea ice, and more in unprecedented, 3-D detail. The satellite also measures heights across Earth's temperate and tropical regions, and takes stock of the vegetation in forests worldwide.

New Low Latency ICESat-2 Datasets

The five new datasets are the result of a joint effort by NASA’s Satellite Needs Working Group Management Office (SNWG MO), ICESat-2 team, and Land, Atmosphere Near real-time Capability for EOS (LANCE).
