Resumo

Coefficients for atmospheric extinction using B and V Johnson filters were obtained and our results indicate the possibility of determining particle densities in suspension in the atmosphere over the city of Rio de Janeiro. Preliminary data, referred in the present study, are favourably compared to densities of both aerosols in conditions of slight haze, and tropospheric dust in clear conditions.Extinction coefficients are comparable to the ones determined by Chabot Observatory in the San Francisco bay area, here taken as a comparison term due to the similarities between both cities.
