摘要：The sunlight that gets to the earth’s surface is composed of three major types of radiation. The Infrared radiation is what gives sunlight its warmth. Visible light helps us see. And lastly the ultraviolet radiation (UV) which poses the most damaging effects of the sunlight cannot be seen nor felt. The UV data over Wuse, Abuja, Nigeria (9.08°N, 7.48°E) was recorded with the Davis wireless vantage pro2 weather station for the year 2020. The research showed that the UV index was higher at the first half of the year and lower at the second half of the year. Months like March, April and May had the highest values of UV index as they contained days of high and very high category of UV index which could pose great damage to the skin and the eye when exposes to the Sun for long. It was also observed that the daily UV index peak hours for the year were between 11:00 hrs-14:00 hrs. The result showed that the UV index experienced significant reduction on days when it rained. Abuja experienced a high UV in the first half of 2020 and a moderate UV radiation during the second half of the year. A mathematical model was developed for the prediction of the Rainfall for the year 2020, using the data of the daily UV index and the monthly UV mean of the same year. The result was found to be very effective.
