Climate Factor (b)

The climate factor is a quantity that compensates the link availability for different types of climates
(weather). In general, microwave links operating in areas with high humidity will have less availability
than those in arid areas, primarily because water is a dispersive mechanism to microwave energy and
causes the main signal lobe to refract and disperse away from the receiver location. The climate factor
values normally used are listed below
