C21A:
Altimetry of the Cryosphere and Polar Oceans I


Submit an Abstract to this Session


Session ID#: 60745

Session Description:
Satellite and airborne altimetry have transformed our capacity to study the polar regions, and the past three decades of measurements have painted a new and unique picture of how Earth’s 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 neighboring land, marine, and atmospheric environments. Altimeter measurements are now central to our awareness and understanding of Arctic and Antarctic 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 polar regions. We welcome submissions based on assessments of past, current, and future missions and on the application of altimeter datasets to observe and model polar environmental change.
