Extensive field programs were undertaken in Alaska during the winters of 1952-1954 to determine the causes of ice-fog formation. Ice fog forms at temperatures near -30 C and below in populated areas and is particularly troublesome at military installations. It poses no threat to health but seriously restricts visibility. The fog is a direct result of supersaturation of the cold air with water vapor from man-made sources. The only methods of curtailing its formation appear to be restricting vapor emission into the air or confining emission to selected fall stacks. Microphotographs of ice fog particles collected at various temperatures are included.
