Given the limited wavelength window of most satellite radiometers, satellite albedo studies need to define narrow-band to a broad-band transformations. Signals from the AVHRR channels on board the NOAA-11 satellite, the Meteosat visible channel and a rectangular spectral band from 0.3 to 2.5 μm were simulated for a set of 20 representative land surfaces. A radiative transfer code was used to obtain top of the atmosphere radiances. The derived signals were then correlated to predict broad-band albedo and the Meteosat response via the two AVHRR signals. The results indicated that the use of the two AVHRR bands makes the narrow-band to broad-band conversion independent of the surface type. Further results illustrated the anisotropic character of surface reflection. -from Authors
