FY-3B/MWRIArctic sea ice concentration

(DT-ASI)

Important Notice: Due to the maintenance of Fengyun Satellite, the data service is temporarily suspended, so the station also suspends the provision of related data services. Please pay attention to the notice notice of this site when restoring data service time.

Data introduction

Sea Ice Concentration (SIC) based on FY-3B orbital brightness data inversion. Key Laboratory of Polar Ocean Process and Global Ocean Change (POGOC), Key Laboratory of Physical Oceans of Ministry of Education, Ocean University of China (POL) development. The sea ice intensity inversion algorithm is a Dynamic Tie point ASI algorithm (referred to as DT-ASI algorithm, Hao & Su, 2015) based on the Bremen University (UB) ASI algorithm. The brightness temperature data has been cross-corrected (Li et al., 2016). Product aging is currently two days (ie, two days before the release of data).
