Abstract

A regression analysis was performed on Landsat MSS data to investigate the dependence of object radiance on the radiance of adjacent areas. The object radiance is increased by a path radiance component attributed to forward scattering in the atmosphere after reflection of solar radiation from the object background. Inclusion of average radiance of a few concentric rings with object reflectance in the regression model for satellite-measured radiance improves the least-squares fit at all sites tested. Multiple regression analysis indicates that radiance of an object is significantly affected by reflectance of background objects up to 500 m away.
