Abstract

Identification and analysis of urban microclimates, concentrating in the heat islands and extreme events of precipitation has been the focus in Brazil's urban climatology researches. Increases in the city temperatures are followed by deterioration of thermal comfort conditions. However, these issues were not prioritized by Geographical Climatology. In this sense, an investigation of thermal comfort analysis in western São Paulo state's medium-sized cities is proposed by two case studies: Presidente Prudente and Marilia. Urban forms and construction materials used derived from different land use and space occupation processes will be analyzed in different neighborhoods by variables income standards. Two techniques will be applied. The first one is a thermal chart from satellite Landsat 7, with ETM+ sensor band 6, with spatial resolution of 60 meters and spectral resolution from 10.4 to 12.5 micrometers with 183x183 scene composition. Urban landscape representative spots will be monitored by digital thermo hygrometers installed in appropriated locations to measure variations in different urban ambients. Questionnaires to identify thermal comfort and Thom's effective temperature index will be applied. Comfortable/uncomfortable areas in the two cities are expected to identification, such as the levels of population's health commitment.
