ICESat-2

ICESat-2

The Ice, Cloud, and land Elevation Satellite-2, or ICESat-2, is measuring the height of a changing Earth one laser pulse at a time, 10,000 laser pulses per second. Launched on September 15, 2018, ICESat-2 will allow scientists to monitor the elevation of ice sheets, glaciers, sea ice, and more—all in unprecedented detail.

ICESat-2 Data at NSIDC DAAC

ICESat-2 collects elevation data over all surfaces spanning the world's frozen regions, forests, lakes, urban areas, and more. These data are downlinked to Earth, reformatted, checked for quality, repackaged into scientific data sets, and delivered to the NSIDC DAAC for distribution and archive.

The Mission

The Mission

Our planet's frozen and icy areas, known as the cryosphere, are a key focus of NASA Earth science research. ICESat-2 will help scientists investigate why, and how much, the cryosphere is changing as the climate warms. The satellite will also measure heights across Earth's temperate and tropical regions and take stock of vegetation in forests worldwide.

ICESat and Operation IceBridge

From 2003 to 2009, the ICESat mission obtained elevation data over ice sheets, information about clouds in polar regions, and topography and vegetation data around the globe. Following ICESat, NASA began Operation IceBridge, a series of airborne campaigns to measure changes to polar land and sea ice and provide continuity between ICESat and ICESat-2. The NSIDC DAAC distributes ICESat and Operation IceBridge data.
