Spectral properties of fog over the Malaspina Glacier, Alaska, in comparison to snow, ice, and clouds
Analysis of Landsat 5 Thematic Mapper (TM) data of the Malaspina Glacier in southeastern Alaska has shown that fog overlying the glacier ice has reflectance characteristics similar to the ice below and that the spectral reflectance of fog can be different from other types of clouds. Fog is more refl...
