Abstract
The paper present four year results of Cloud attenuation measurements carried out at Covenant University, Ota, Nigeria. The links operate at frequency of 12.245 GHz and the cumulative distribution function for monthly Cloud attenuation have been estimated from the 4-year measured spectrum analyser data. The result of the visually measured Cloud and Satellite Cloud cover data are presented. The monthly variability shows that the highest cloud attenuation at the station occur in August, reaching a maximum of 3.96 dB for 0.01% of time; which corresponding to an average cloud cover of 89.86% and 75.36% by ground and satellite data respectively of which Nimbostratus (Ns) is average of 29.1%. The lowest cloud attenuation at the station occur in September, with a value of 2.5 dB for 0.01% of time; corresponding to an average cloud cover of 90.3% and 77.26% by ground and satellite data respectively, of which Nimbostratus (Ns) is average of 28.9%.
