19 January 1984 Apparent infrared (IR) Cloud Radiance Model
Author Affiliations +
The infrared radiation from clouds, which results as clouds emit heat and scatter sunlight, is an important consideration in the design of high-altitude sensor systems. The radiation detected by a high-altitude sensor depends both upon the origin and the path of the rays. The purpose of this paper is to show how such variables as the observation angle, the solar zenith angle, the particle scattering angle, the wavelength band and cloud altitude are incorporated into a comprehensive background description, and to illustrate the effect of these parameters on backgrounds. The description uses previously developed models for its separate components.
