Topography Featured Observation Method: ICESat-2

NASA's Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) allows scientists to measure the elevation of ice sheets, glaciers, sea ice, and land across Earth's temperate and tropical regions, as well as take stock of the vegetation in forests worldwide. ICESat-2 carries the Advanced Topographic Laser Altimeter System (ATLAS), which sends 10,000 pulses of laser light to the ground per second and then measures how long it takes them be reflected back by the surface to determine the area's elevation. Learn more about ICESat-2/ATLAS near real-time data provided by NASA's Land, Atmosphere Near real-time Capability for Earth observation (LANCE). ICESat-2 carries the Advanced Topographic Laser Altimeter System (ATLAS), which sends pulses of laser light to the ground, collects the returning photons in a telescope, and records the photon travel time.

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).
