Analysis of the ultraviolet index in the region of Puno, Peru

Abstract

The work had the objective of analyzing the values of the ultraviolet index in the Puno region, for which it has been considered a point of reference in the thirteen provinces. To obtain ultraviolet index values, data from the weather station of the city of Puno for the period 2016-2021 has been considered and with this obtain a correction equation for the data obtained from the Giovanni NASA website and thus obtain maximum daily values for the Puno region. A theoretical model has been considered to obtain the ultraviolet index, which is for clear sky conditions. The evaluation statistics used are the standard error and the linear correlation coefficient between the estimated data and values measured by the weather station. It is concluded that it is possible to obtain UV index values for the city of Puno with a reliability of 95% and an error of 0.8, and for the Puno region it is possible to obtain UV index values by means of the correction equation, where the very high and extreme UV index values occur in the summer season.
