THE METEOROLOGICAL FACTORS AFFECTING PHOTO-GRAPHIC RECONNAISSANCE FROM VERY HIGH ALTITUDES

Abstract

Successful missions of photographic mapping and photographic reconnaissance from the air require a minimum of cloud cover. Cloud-cover forecasts are obtained prior to each mission. For photography from very high altitudes with highresolution camera systems, the effects of other obscuring factors besides clouds must be considered. Dust and other aerosols suspended in the atmosphere reduce the brightness contrast of ground targets. Shimmering due to optical turbulence may distort details and prevent target recognition. A brief survey is given of the obscuring factors affecting photography from very high altitudes. Numerical data on aerosols and optical t r ulence are included. (Author)
