Abstract

The aim of this study was to analyze the urban growth of Bahia Blanca city and its impacts on the microclimate considering its inhabitants perception. LANDSAT satellite images were processed for the period 1984-2014. The urban area, the temperature and the biomass was estimated. Temperature, relative humidity and wind speed from the Servicio Meteorologico Nacional (Argentina) were analyzed. The growth of the city has reduced the biomass. The LST decreased 0.6 ºC due to the increasing of shadows generated by buildings and the heat capacity of their materials. The opinion of the citizen corresponded with the meteorological data analyzed. Consultations with stakeholders generated useful information to guide city planning, public policy and decision making to improve the inhabitants’ quality of life.
