Improving Our Understanding of Antarctic Sea Ice with NASA's Operation IceBridge and the Upcoming ICESat-2 Mission [PDF]

Antarctic sea ice is a crucial component of the global climate system. Rapid sea ice production regimes around Antarctica feed the lower branch of the Southern Ocean overturning circulation through intense brine rejection and the formation of Antarctic ...

Estimation of Water Elevation Using ICESat-2 Satellite

Engineer: Journal of the Institution of Engineers, Sri Lanka
Due to the lack of in-situ gauge data, remote sensing is crucial for water level monitoring. This study presents a thorough examination of water level variations in nine main Sri Lankan reservoirs over the past five years, using data from the Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) Advanced Topographic Laser Altimeter System (ATLAS).
