WebJan 20, 2024 · TM band 6, a thermal infrared band, is sensitive to infrared surface temperature and has a resolution of 120 m. Spectral reflectivity of snow as determined from the visible, near- and middle-infrared bands is dependent on snow parameters such as grain size and impurity content of the surface layers of the snow (Reference Dozier Dozier 1984). WebThe table above shows the reflectivity of various common materials. For example, snow reflects 80% of the light that falls on it, which means that it absorbs 20% and so 80% + …
