A STATISTICAL MODEL FOR DETERMINATION OF THE RADIATIVE TEMPERATURE AT BLACK-BODY SURFACES, BASED UPON SPECIFIC WINDOW-RADIANCE VALUES MEASURED OVER A RANGE OF ZENITH ANGLES BY NIMBUS II RADIOMETER.

Abstract

Computed Channel 2 or window radiances for the Nimbus II optical sensor system were made available to the author by the Meteorological Satellite System of ESSA for each of the 106 model atmospheres considered by Wark et al (1963). Multiple regression equations relating the emitted black-body intensity from 'black' interfaces to the independent variables (1) 'observed' specific filtered radiance and (2) total optical path, were set up for each of seven zenith angles in the range theta = 0 degrees to 60 degrees, and for each of 62 randomly selected cases from the Wark sounding-catalog. Both variables gave high statistical significance, with the former accounting for the primary part of the variance of the dependent variable, with variable (2) always contributing in such a way as to account for some of the atmospheric absorption along the sensing direction.
