Validation of the Tropospheric Ultraviolet and Visible (TUV) model in the province of Huancayo

Abstract

The Andean region of Peru is located in a tropical zone with low tropospheric ozone concentration, making it prone to greater exposure to ultraviolet B (UV-B) radiation, which causes damage to the skin, eyes, and immune systems. Despite awareness of the situation in the Andes, the constant increase in urbanization and the number of vehicles on the road, as well as manufacturing industries, may further deplete the ozone layer in this region. Therefore, the research work consisted of estimating the variability of the total ozone column in February 2010 in the Mantaro Valley using the tropospheric Ultraviolet and visible (TUV) model, and for its validation, ground measurements were taken, synchronizing it with the Ground-Based Ultraviolet (UV) GUV-511 Biospherical Inc. spectral radiometer, which provides measurements at 305, 320, 340, and 380 nm and the ultraviolet (UV) index. Spearman's correlation coefficient was determined for the statistical evaluation and validation of the TUV model. A value of 0.86 (p>0.05) was obtained for the UV index for Huancayo. In addition, a maximum clear sky radiance was given at 305 nm, 320 nm, 340 nm, and 380 nm of 0.12, 0.4, 0.64, and 0.83 W/m2nm, respectively, and a UV index of 12. It is concluded that the use of the TUV model allows the annual climate of the RUV in the ECAMP to be predicted.
