AB Solar Ultraviolet Radiation (UVR), which is identified as a major environmental healthhazard, is responsible for a variety of photochemical reactions with direct effects on urban andaquatic ecosystems, human health, plant growth, and the deterioration of industrial systems. Groundmeasurements of total solar UVR are scarce, with low spatial and temporal coverage around theworld, which is mainly due to measurement equipment maintenance costs and the complexities ofequipment calibration routines; however, models designed to estimate ultraviolet rays from globalradiation measurements are frequently used alternatives. In an experimental campaign in Burgos,Spain, between September 2020 and June 2022, average values of the ratio between horizontal globalultraviolet irradiance (GHUV) and global horizontal irradiance (GHI) were determined, based onmeasurements at ten-minute intervals. Sky cloudiness was the most influential factor in the ratio,more so than any daily, monthly, or seasonal pattern. Both the CIE standard sky classification and theclearness index were used to characterize the cloudiness conditions of homogeneous skies. Overcastsky types presented the highest values of the ratio, whereas the clear sky categories presentedthe lowest and most dispersed values, regardless of the criteria used for sky classification. Themain conclusion, for practical purposes, was that the ratio between GHUV and GHI can be used tomodel GHUV.
