Sulfatos y nitratos en partículas atmosféricas y su relación con algunos parámetros ópticos

Abstract

Approximate concentrations of sulfates and ni trates of atmospheric aerosol are determined and their relationships between visibility and turbidity in the visible and ultraviolet regions of the spectrum are obtained. The results show that there is a high correlation of these radicals with the turbidity parameters. It is possible to estima te the daily mean of visibility and Ángstrom 's turbidity coefficients by fitting a multiple-variable regression to the concentrations of sulfates and nitrates. Nitrates play a more important role than sulfates with the optical parameters studied in this work in spite of the fact that the concentration of sulfates is larger than the ni trates.
