The report delineates world patterns of various soil types that have a potential for the generation of atmospheric sand and dust either through natural causes or man-induced mechanical agitation. This is done by three maps one showing soil types as determined by classes of particle size a second showing seasonal durations of wet, moist, and dry soil conditions and a third portraying the distribution of siliceous, vitreous, saline, and acidic soils, soils with high percentages of iron and aluminum, and soils consisting largely of montmorillonitic clays. The maps provide the basis for a realistic assessment of Army aircraft design problems which can be attributed to sand and dust. Additionally, they contribute to the total store of environmental information needed to determine the environmental criteria to be adopted for the design and testing of Army VSTOL aircraft systems.
