Scientific paper

The anisotropic factors of quasi-three-dimensionally modeled areas in the Alps (Europe) with an extent of approximately 60 sq km are calculated for two wavelengths in the solar spectral region. For light snow cover, even simple assumptions concerning the reflection function of the elements of area return very accurate values of absorptance and radiation balance. With increasing snow cover, however, large errors can occur if reflection anisotropy of the snow fields is not adequately considered. With Meteosat measurements, anisotropic factors, f, are required which also take into account this effect, using NOAA AVHRR (Advanced Very High Resolution Radiometer) measured values and assuming that f = 1 already yields very accurate absorptances by imposing a restriction to the midday overpasses and positions of the areas around a nadir of +/- 273 km.
