Abstract

Recent ground based interferometer measurements of the spectral characteristics of natural sky radiance and the radiance emanating from the effluents of a conventional power station smoke stack are presented. The interferometer measurements were performed at a spectral resolution of 0.5 - 1 cm-1. The meteorological conditions existing at the time of the measurements was recorded as well as the operating conditions of the woke stack. Comparisons are given between calculated sky spectral radiance using meteorological data and measurements at both ground level and at 15,000 ft altitude. The calculations were performed using both a line-by-line approach and a low resolution method (LOWTRAN 4 Radiance Model). The sensitivity of both methods to uncertainties in meteorological conditions is discussed.
