Abstract
Atmospheric variability affects the utility of most existing and planned DOD weapons systems. The goal in assessing the impact of the atmosphere is to establish the frequency and extent of the system performance degradation caused by the environment and identify both design changes and operational employment procedures which will minimize the atmospheric impact and thereby optimize the system performance. With proper understanding of the effect of the atmosphere on system performance coupled with reliable evaluations of the spatial and temporal occurrences of the constraining environmental phenomena, optimization of system performance is possible. In the case of high energy beam propagation through the earth's atmosphere, clouds are a limiting atmospheric phenomena. With current technology, clouds in the line-of-sight are "show stoppers". Hence to maximize the availability of high energy weapons, sites with low frequencies of cloud occurrence should be selected. For several reasons we have been collecting and archiving meteorological satellite imagery over the western U.S. for use in evaluating cloud conditions at the local scale. Visible light data have been archived during daylight hours and thermal infrared data collected 24 hours each day from the GOES satellite. Using these data, composite cloud climatology images have been constructed which give the frequency of occurrence of cloud cover by hour and month over the western U.S. with a spatial resolution on the order of the satellite pixel resolution. This paper will describe the techniques used in the construction of these composite cloud climatologies and their use in local area studies. Additional applications of this new satellite-derived cloud climatology will be discussed.
