Kibirige David Abstract: This study examined the Influence of Cloud Optical Depth on the Solar Radiation to establish the impact of clouds on the intensity and strength of the solar beam radiation propagated on earth's surface from the sun in Kampala area at Makerere University using CMP6 pyrometer, UV daily dose and NILU-UV instrument. The data was gotten from the records Department at Makerere University from the Physics Department. The Pyrometer data which is used in this study is from 2018 to 2020, and this Data gives the irradiance. MATLAB Code is used to help sort out and remove all repeated data within the Pyrometer data and then another code to work on the NILU UV data to sort out and pick column of interest. The radiation measured from the pyrometer is used for analysis in this study. The result shows a negative correlation of, -0.4537, -0.4027, -0.3692 for global irradiance, direct irradiance and UV daily dose component respectively with cloud optical depth.
