                         irradiation in Brazil. The model parameterizes the influence of 
                         aerosols in the solar radiation transmittance using climate 
                         averages of horizontal visibility, which does not represent the 
                         actual atmospheric condition in Brazil, especially during dry 
                         season. In clear sky conditions, aerosols are a major source of 
                         bias in solar radiation models. Their concentration have large 
                         spatial and temporal variability particularly in the Brazilian 
                         Midwestern region from April until October, due to forest fires, 
                         and in Southeastern region due to pollution from megacities. In 
                         this study, meteorological data from METAR comprising the years of 
                         2006, 2007 and 2008 were analyzed to evaluate the seasonal 
                         variability of the horizontal visibility in Brazil to better 
                         represent the influence of aerosols on the model estimations of 
                         surface solar irradiation. New horizontal visibility values was 
                         generated to each month simulated, to provide input data to the 
                         BRASIL-SR model and site specific ground data were used to 
                         validate the model estimates. The global, direct beam and diffuse 
                         solar irradiation estimates obtained by making use of the new 
                         horizontal visibility data presented an overall lower BIAS and
