Satellite imagery taken from Landsat I were used to determine terrestrial albedo and its changes with location and season in the basin of Sonoita Creek (31°45′N 110°43′W). A simple linear equation was derived to link the albedo with the optical density of the imagery. The modeling approach was based on the cyclic nature of the energy exchange between earth and space on the one hand and on the local density on the developed film as an output on the other hand. The results showed acceptable agreement between photographic and radiometric method for albedo determination.
