PINEDO V, J. L et al. Spectral signature of ultraviolet solar irradiance in Zacatecas. Geofís. Intl [online]. 2006, vol.45, n.4, pp.263-269. ISSN 2954-436X.

This study presents an analysis of the global ultraviolet spectral irradiance (290-400 nm) registered in Zacatecas, a city near the Tropic of Cancer, located at 2500 m above sea level, latitude of 22° N and longitude of 102°W. The spectra have been measured using a Bentham radiometer with a 0.5 nm step in wavelength. The measurements show relatively high levels of ultraviolet irradiance (UV), which may be characteristic of areas close to the Tropic of Cancer. Faced with an increase of the incidence of skin cancer among the population of Zacatecas, these measurements highlight that a damage prevention plan is required.
