WebOPTICAL PROPERTIES OF LIQUID WATER AND ICE The basis for the spectral measurement of liquid water is derived from the optical properties of liquid water in the 400-40 2500-nm range. To spectrally measure liquid water in snow, its absorption must be separable from the absorption due to frozen water. The complex refractive indices (Warren, 1982; Kou WebNov 5, 2008 · Multispectral visible/near-infrared (VNIR) earth observation satellites, e.g., Ikonos, Quickbird, ALOS AVNIR-2, and DMC, usually acquire imagery in a few (3 – 5) spectral bands. Atmospheric correction is a challenging task for these images because the standard methods require at least one shortwave infrared band (around 1.6 or 2.2 µm) or …
