Description
Summary:With an automatic sequential precipitation collector, 52 rainy events were sampled at Vitoria (Spanish Basque country) in 1986. The chemical composition of each rainy event was studied and classified, using statistical techniques of multivariate data analysis (linear correlation + principal component analysis) and an automatic classification (length χ 2) of the rainy events. These techniques enabled us to show, taking into account the influence of the meteorological conditions in which the precipitations formed, the presence, in Spanish Basque country, of acid rain episodes with an anthropogenic origin. These episodes are certainly reinforced by the trans-border transport from Southern France. Moreover, rainy episodes were shown to have a basic character due to a local source of terrigenous particles.
