Use of spatial interpolation technique for determination of geoclimatic factor and fade depth calculation in Southern Africa

Different authors have adopted various techniques to resolve the clear-air radio-propagation effect problems. These authors have presented different modeling techniques based on the radio propagation variables of the region in question. These variables are determinable from the local radio propagation data of the region in question. This paper uses the radiometeorological data collected in Durban, South Africa and in Maun, Botswana to determine the geoclimatic factor (K) variable. This is then used in implemented link designs to calculate the fade depth and worst month for these two locations.
