Altimetry of the cryosphere: CryoSat-2, ICESat-2 and beyond
Session ID#: 77280
Session Description:
Satellite and airborne altimetry have transformed our capacity to study the cryosphere, and the past three decades of measurements have painted a unique picture of how Earth’s glaciers, ice sheets, ice shelves, sea ice, and polar oceans evolve. As global temperatures have risen, so too have rates of snowfall, ice melting, and sea level rise, and each of these changes impacts upon the neighbouring land, marine, and atmospheric environments. Altimeter measurements are now central to our awareness and understanding of Arctic, Antarctic, and Alpine environmental change. This session brings together studies that innovate and utilise measurements developed from satellite and airborne altimeter platforms to examine the complementarity of approaches across scientific disciplines, and to advance our understanding of the cryosphere. We welcome submissions based on assessments of past, current, and future missions and on the application of altimeter datasets to observe and model environmental change.
