Cryospheric Science Websites
Cryospheric research at NASA's Goddard Space Flight Center addresses the physics of ice sheets and glaciers, sea ice, snow on ice and land, and their roles in the global climate system.
WFF scientists support cryospheric research through our involvement with airborne and space-based laser altimetry. WFF Project websites include:
Airborne Oceanographic Lidar (AOL)
The NASA Airborne Oceanographic LIDAR (AOL) project is involved in several different ways of remotely measuring chlorophyll and other biological and chemical substances in the world's oceans. The AOL uses sensors that are flown in aircraft to make these measurements. The AOL website has been retired.
+ Airborne Topographic Mapper (ATM)
The Airborne Topographic Mapper is a scanning laser altimeter which has been carried onboard the NASA P-3B aircraft and on a smaller NOAA Twin Otter. The ATM platform incorporates the laser altimeter, GPS data, and inertial navigation packages.
+ Geoscience Laser Altimeter System (GLAS)
GLAS is a laser altimeter system designed to measure ice-sheet topography and associated temporal changes, as well as cloud and atmospheric properties. GLAS is the primary instrument on the Ice, Cloud, and land Elevation Satellite (ICESat).
