Measurements of beam transmittance and path radiance for correcting Landsat data for solar and atmospheric effects
Abstract
Beam transmittance and path radiance in the four optical bands of the Landsat satellite can be determined from corresponding measurements of solar radiance as a function of solar elevation and sky radiance as a function of azimuth angle. The necessary data and computations to correct remote-sensing measurements for optical effects of the atmosphere are presented. A correction of measured meteorological data (atmospheric pressure, temperature, and relative humidity) with the measured beam transmittance has been attempted.
