SEA ICE AND ICE SHEET SURFACE ROUGHNESS CHARACTERIZATION AND ITS EFFECTS ON BI-DIRECTIONAL REFLECTANCE
The roughness of sea ice can affect its bidirectional reflectance distribution function (BRDF) thus influencing retrieval of its physical properties from satellite. We leverage WorldView-1 and Multi-angle Imaging SpectroRadiometer (MISR) remote sensing data sets collected over sea ice and the adjace...
