The UV-B monitoring project focused on modeling the ultraviolet radiation index across the state. In Colorado, UV-B is measured directly at only 3 places and a map is prepared from readings at those stations. Because the number of stations is not comprehensive for the entire state, the maps are not representative of the correct UV-B radiation received by any point in the state of Colorado. Incoming UV-B radiation is dependent on a lot of factors, including but not limited to, solar irradiance, ozone layer cover, cloud cover, and the number of aerosols. Better maps are needed by farmers to estimate crop yield and reduce crop damage due to UV-B radiation. The main focus of this project was to gather relevant datasets that would aid in the modeling of incoming UV-B radiation.Intern: Alfonso de LaraReport: UV-B monitoring, model of ultraviolet radiation index
