Remote Sensing of the Cryosphere: Sea Ice
Session ID#: 249690
Session Description:
Sitting at the interface of the polar oceans and the atmosphere, sea ice is a key component of the Earth’s climate system and a sensitive indicator of climate change. Remote sensing has transformed our understanding of the fast-changing Arctic and Antarctic sea ice systems and is essential for capturing complex changes that occur at a wide range of temporal and spatial scales. This session aims to highlight recent progress made in the remote sensing of sea ice, including descriptions of sea ice geophysical properties such as thickness, motion, extent, lead fraction, floe size, melt ponds, snow on sea ice, etc. Some of the key topics include algorithm improvements, novel techniques, applications for model evaluations, validation with in situ data, process studies and interdisciplinary investigations. We strongly encourage submissions on current remote sensing opportunities (e.g., CRYO2ICE, RCM, SWOT, commercial sensors) and preparation for upcoming satellite missions (NISAR, CRISTAL, AMSR-3, CIMR).
