The physical basis for sea ice remote sensing
Webb11 okt. 2024 · Abstract. Arctic rain on snow (ROS) deposits liquid water onto existing snowpacks. Upon refreezing, this can form icy crusts at the surface or within the snowpack. By altering radar backscatter and microwave emissivity, ROS over sea ice can influence the accuracy of sea ice variables retrieved from satellite radar altimetry, … Webb19 mars 2024 · sea ice analysis by satellite remote sensing as early as the 1980s. Sea ice detection is mainly carried out by remote sensing based on visible light and microwave remote sensing. The sea ice remote sensing based on visible light is mainly detected by medium and low res-olution optical sensors,2 and the relatively intuitive images can be …
