CCS.50: Advanced observations of sea ice by satellite SAR in a changing climate
Sea ice in polar regions can be dramatically affected by climate change, with thinning sea ice, longer melt seasons and increased new ice formation and it is crucial to monitor these changes.
Synthetic aperture radar (SAR) is an invaluable remote sensing sensor with wide-spatial coverage over hundreds of kilometers and high spatial resolution capabilities at meter scales. Moreover, a SAR actively illuminates scenes at microwave frequency regardless of weather and darkness, offering an excellent opportunity to monitor polar regions.
With the development of SAR polarimetric and interferometric techniques, many studies have demonstrated SAR as a promising tool to characterize sea ice properties through scattering mechanisms, estimate sea ice roughness, identify sea ice classes, and retrieve sea ice elevations.
This session focuses on new techniques to monitor sea ice and the latest observations of sea ice in a changing climate using spaceborne SAR. New techniques include advanced algorithms and models to characterize sea ice using various polarizations and frequencies. The session covers the latest observations of sea ice in both Arctic and Antarctic regions, where the sea ice properties can be significantly different due to the diversity in growth conditions. The session also underlines the evolution of sea ice in recent decades and the effects of climate change on the sea ice characteristics.
The aim of this session is to bring new ideas to achieve operational and synergistic sea-ice monitoring from the multiple SAR missions in the upcoming years. Specifically, the spaceborne SAR missions such as the TSX/TDX and the future LOTUSat Missions at X-band, the Sentinel-1 and RADARSAT Constellation at C-band, and the upcoming NISAR Mission at L and S bands, provide optimal conditions for observing sea ice over extensive spatial coverage at shorter revisit time. Therefore, the session allows the community to obtain the state-of-the-art sea ice observations and to develop more advanced sea-ice monitoring methods in the era of big SAR data.
The session also provides an opportunity for scientists to discuss possible future field campaigns (e.g., icebreaker cruise measurements) coordinated with the satellite SAR data acquisitions. Such measurements can be used as reference data and would be highly valuable for developing accurate algorithms from SAR imagery. Last but not least, the session aims to show the latest sea ice observations under a changing climate to help understand the geophysical processes of sea ice and to assess the impacts of sea ice change in a changing climate.
