摘要: Increased use of remotely sensed data for estimation land-surface climatological variables such as the radiation and energy balance has underscored need to understand errors inherent in remote sensing systems. The effects viewing geometry on signal received at sensor have been examined a variety surface types, but systematic study how may introduce error into measurements climate parameters is lacking. In this paper, close-range used assess caused by net radiation, an important variable. Estimates were made inserting values albedo temperature budget equation. Two contrasting surfaces, one vegetated bare, evaluated seven view angles five azimuth angles. each combination angle then compared t...
