Surface Albedo Estimates from Nimbus-7 ERB Data and a Two-Stream Approximation of the Radiative Transfer Equation

Solar zenith angle-dependent surface albedo is determined by equating top of the atmosphere (TOA) albedo evaluated from Nimbus-7 data with TOA albedo predicted by a two-layer, two-stream radiative transfer model of the atmosphere. Results are presented for solar zenith angles ten than 82° for two locations in Western Australia, the Sahara/Arabian desert and the Ar Rab Al Khali basin in Saudi Arabia. They are compared with previous estimates, …
