Abstract

This research project is aimed at improving knowledge on atmospheric and geographical phenomena inherent in estimates of surface ultraviolet radiation (R-UV). However, studies involving R-UV should not merely limit themselves to scientific objectives, but also supply parameters for the support of public and social policies for raising the population’s awareness of the harmful effect of excessive exposure to the sun. Given this range of motivations, this project proposes a set of studies on R-UV to be carried out in the State of São Paulo, given that the region presents important points in relation to the theme. From the point of view of public health, the region is home to around 25 per cent of the Brazilian population and has the highest number of skin cancer diagnoses in the country, and from the scientific point of view, possesses relevant regions of interest due to its geographical and atmospheric differences, as one of the world’s largest urban agglomerations, the city of São Paulo, the coastal and mountain tourist resorts. Due to this geographical heterogeneity, the implementation of this project, which includes the acquisition of sensors for measurements of global fluxes of R-UV, has the objective of carrying out theoretical-experimental studies related to the influence of: a) presence of aerosols; b) surface altitude; c) ground reflectance; d) cloud cover; and, in addition, taking advantage of the undertaking of systematic measurements, it is proposed to monitor levels of R-UV in large urban and tourist centers.
