     urban climate can have severe impacts on people who use outdoor spaces within a city. in its essence, urban climate is directly linked to the configuration of street axes, building heights and their attributes. thus, the role of urban planners can be crucial for guaranteeing outdoor thermal comfort and air quality in open spaces. this paper presents observed and estimated relations between urban morphology and changes in microclimate and air quality within a city center. two approaches are presented, showing results of field measurements and urban climate simulations using the envi-met software suite. from measured microclimatic data and comfort surveys, carried out in downtown curitiba, brazil, the impact of street geometry on ambient temperatures and on daytime pedestrian comfort levels was evaluated, using the sky-view factor (svf) as indicator of the complexity of the urban geometry. the impact of street orientation relative to prevailing winds and the resulting effects of ventilation (air speed and spatial distribution) on the dispersion of traffic-generated air pollutants were additionally analyzed by means of computer simulations. results show the impact of urban geometry on human thermal comfort in pedestrian streets and on the outcomes of pollutant dispersion scenarios.
