Wintertime daily Arctic sea ice surface roughness from FY-3E dual-band scatterometer (WindRAD) during 2022-2024
Year: 2026
Type: dataset
Abstract: This dataset contains wintertime (Nov-Apr) daily Arctic sea ice surface roughness derived from FY-3E dual-band WindRAD scatterometer (2022-2024). The spatial resolution is 10*10 km projected onto a polar stereographic grid. The daily file (in netCDF format) contains three variables: "lat", "lon", "roughness", and "sit". "lat" and "lon" are geolocations of grid cells. "roughness" is the RMS height of sea ice surface (unit: m). "sit" is the sea ice type, in which value=1/2/3 represents thin ice (thickness<50 cm)/ first-year ice (thickness>50 cm)/multi-year ice (thickness>50 cm). The thickness data comes from the SMAP-SMOS Arctic thin ice thickness product provided by the University of Bremen, while the FYI and MYI type comes from the OSI SAF global sea ice type product. For the details of the dataset and the retrieval algorithm, please see the related paper which is under review now (the information will be updated once the paper is published online).
