NNA: Remote Sensing of Arctic Sea Ice Using the Super Dual Auroral Radar Network

Long-running observations of sea ice extent and characteristics are crucial to understanding environmental changes in the Arctic. The Super Dual Auroral Radar Network (SuperDARN) is an international network of ground-based, high-frequency (HF) space weather radars which have operated continuously in the Arctic and Antarctic regions for more than 30 years. The objectives of this project are to analyze historical and ongoing SuperDARN ground backscatter measurements for extraction of Arctic sea ice parameters. Comparisons will be made to sea ice measurements obtained from space-based microwave remote sensors. An operational sea ice data product derived from SuperDARN HF radar observations will be submitted to the Arctic Data Center for long-term preservation and accessibility by the broader Arctic research community.
