Earth-atmosphere system and surface reflectivities in arid regions from Landsat MSS data

摘要: Abstract Previously developed programs for computing atmospheric transmission and scattering of the solar radiation are used to compute ratios Earth-atmosphere system (space) directional reflectivities in nadir direction surface Lambertian reflectivity, four bands Landsat multispectral scanner (MSS). These presented as graphs two water vapor levels, a function various sun elevation angles. Space vertical reported selected arid regions Asia, Africa Central America from spectral radiance levels measured by MSS. From these space reflectivities, computed applying pertinent graphs. estimate albedo entire spectrum. The estimated albedos range 0.34–0.52, higher than values most previous researchers measurements, but consistent with laboratory situ measurements.
