Abstract
Given the impact of greenhouse gases on the change in solar radiation and the increase in ultraviolet radiation as a result of the depletion of Ozone by these gases. This study highlighted the relationship between UVB and O3 over Libya. Since Libya is a large country with a climate that varies from one region to another, the variation in Ozone and UVB amounts varies among these regions. In the northwestern regions, UVB is low and thus O3 is high, which is the opposite of the southern regions. A strong inverse relationship was found between them, with the correlation coefficient for the periods 2005-2015 and 2016-2022 being approximately -0.8243 and -0.60796, respectively. Using spatial analysis to identify high and low areas and find the spatial correlation, an inverse correlation was observed. In addition to calculating the difference between the two periods and identifying the most accurate regions, it was found that Tripoli and its suburbs have the highest amount of UVB, while the south has less UVB due to the change in solar radiation intensity over time and the increase in greenhouse gases in the north of the country, especially in the western region.
