This thesis presents an analysis of atmospheric refractivity conditions in the Arctic Marginal Ice Zone. The fundamental principles of atmospheric effects on electromagnetic wave propagation are presented along with methods to assess these effects. Using these principles, a determination of the occurrence of atmospheric ducts is made from meteorological data gathered during the Arctic Marginal Ice Zone Exercise, 1983, MIZEX-83. The optimum coupling height, thickness and intensity of each duct are calculated and statistically compared. Duct occurrence is related to area meteorological conditions. Based on area refractivity, the potential for enhanced electronic warfare operations is evaluated.
