WebA model for calculating snow bidirectional reflectance at any wavelength in the solar spectrum is presented. The method is based on the radiative transfer theory by using the adding/doubling method. The model includes polarization information which is quite new for snow and can help to interpret relevant remote-sensing data. WebIce and snow generally show a high degree of reflection at visible wavelengths (VIS; ca 0,4 – 0,75 µm), lower reflection in the NIR (Near InfraRed, wavelength ca 0,78 - 0,90 µm) …
