Impacts of Meteorological Variables on Air Quality in The Region of Grande Vitória, Espírito Santo, Brazil

Abstract

The objective of this study was to determine the impacts of meteorological variables, such as temperature, relative humidity, wind speed and precipitation, on the air quality in the Region of Grande Vitória, Espírito Santo, Brazil, considering the pollutant PM10 and using the Logit model. The period of study was from January 2005 to December 2010 and, in this study, the air quality was classified as “not good” and “good”. The day of the week and season effects over the air quality “not good” were also estimated. The results showed that the precipitation and the wind speed contributed significantly to the reduction of the probability of air quality “not good”. In addition, during the weekends the probability of air quality “not good” was greatly reduced and in the autumn and winter seasons the probability of air quality “not good” falls significantly.
