Morfologia urbana e qualidade do ar: uma proposição metodológica aplicada em caso empíricono Rio de Janeiro

Abstract

Considering the importance of cities as pollutants emission sources and population hubs, the work researches possible impacts of the urban form aspects on pollutants concentrations. The paper discussesthe state of art of interactions between air quality and urban form indexes, compares and tests different indicators of urban form, including a proposed tridimensional compacity index. It.s suggested a way of modeling and testing these relations andpresented a case study in Rio de Janeiro city, involving statistical methods applied to pollutants (SO2, CO e PI), morphological variables (ground space index and verticalization) and meteorological (wind . direction and speed - , rainfall and air temperature). Results point to gradesof influenceof the ground space index and verticalizationon concentrations of considered pollutants.
