Validation and Analysis of UV Radiation Time Series Collected in Different Peruvian Sites

Abstract We evaluate a set of ultraviolet solar radiation (UVR) measurements collected in six locations in Peru: Ica, Tacna, Moquegua, Arequipa, Cajamarca and Marcapomacocha, whose altitudes vary from sea level to 4479 m. The analysis involved the validation and analysis of the ultraviolet index (UVI) and the daily erythemal doses (D-Er). Clear-sky filtered data were compared with numerical simulations provided by the Tropospheric Ultraviolet and Visible (TUV) radiation model in order to estimate numerical regression equations. These equations showed high determination coefficients (R2 > 0.91) statistical significance (p
