ABSTRACT This work investigated the atmospheric conditions over Makurdi in order to access the availability of solar radiation due to the fact that solar radiation reaching the Earths surface depends on the climatic condition of the location. The monthly mean daily global solar radiation and air temperature data for Makurdi covering a period of 10 years 2000-2010 were obtained from Air Force Base Makurdi. The model for shortwave solar energy balancing at the edge of the Earth atmosphere was adopted in this work. The results show that the global solar radiation and the albedo depict direct opposite relationship while the Earths surface temperature varies directly with the global solar radiation since surface temperature is the reflection of both the duration and intensity of solar radiation. The highest albedo of 0.7 was obtained in August the peak of cloud activity while the lowest albedo of 0.5 was recorded in November when it was relatively cloudless and dustless. The albedo simulated corresponds with that obtained in other locations when compared.
