Retrieval of ice information from SAR for data assimilation

Automated extraction of ice information from SAR is challenging, yet important for many applications including data assimilation in ice numerical systems. In this talk, I will give an overview of our techniques for automated retrieval of ice information from dual-polarization (HH-HV) RADARSAT-2 ScanSAR Wide images suitable for subsequent assimilation in Environment and Climate Change Canada (ECCC) Regional Ice-Ocean Prediction System (RIOPS). These techniques were developed and verified based on many thousands of RADARSAT-2 images and corresponding Canadian Ice Service image analysis products collected between 2010 and 2016. We found that year-long assimilation of automated SAR retrievals in ECCC RIOPS improves ice concentration analyses, particularly in the situations where the high spatial resolution is important including small inland lakes and the areas located near the shoreline. The developed techniques are being currently adapted to the data stream from the recently launched RADARSAT Constellation Mission (RCM).
