Abstract

The present study aims to analyze the ultraviolet index in the city of Puno by applying an empirical model, in order to evaluate its variability and behavior over time. To do this, global solar radiation and ultraviolet index data corresponding to the period 2016-2018 were examined. The study was carried out at the Universidad Nacional del Altiplano - Puno, located in the city of Puno. For the analysis, measurements obtained from the DAVIS Vantage PRO 2.0 Plus meteorological station were used, considering the variables of global solar radiation and ultraviolet index. The statistical processing included the calculation of the mean absolute error, as well as the coefficients of determination and correlation between the measured values ​​and those estimated by the model. The results indicate that the proposed model for estimating the ultraviolet index in clear skies presents a high degree of fit with the observed data, reaching an approximate correlation of 0.988. Furthermore, the model developed for cloudy conditions shows a significant correspondence with the measurements, with a correlation of 0.984 during the study period. These findings support the reliability of the proposed models for estimating the ultraviolet index under different atmospheric conditions.
