This is a report of experimental work performed during the period of September 1956 to June 1957 on the correlation of backscattering with atmospheric transmission. Measurements were made for a variety of conditions where the meteorological range varied from less than 0.10 mile to more than 40 miles in atmospheres which were free of industrial pollution. Analysis of the data shows the following relationship: V=C/S1.5, where V=meteorological range, C=constant, and S=backscattered signal. The point spread about the curve indicates that meteorological range can be determined from the backscattered signal with an accuracy of 20% for all visibilities in the ranges studied.
