Ilhas de calor em Vitória da Conquista - BA: Identificação e proposta para criação de áreas verdes

Abstract

High temperatures in cities are the result of critical environmental issues. Scientists all over the world have made every effort to understand the factors that increase temperature and its effects in towns and cities. Current study analyzes heat islets within the city area of Vitória da Conquista BA Brazil. Heat-identification Methodology comprised thermal sensor data from satellites LandsatTM 5 and 8, with atmospheric corrections and conversions in temperature units in grey tones produced by satellite for surface temperature rates. Results showed temperature variations within the city area comprising seven heat islets featuring site characterized by high asphalt area rate and lack of greenery. Ten potential areas were identified for the implementation of green areas to improve temperature conditions in the identified hot spots. Results may be a help in urban planning for decision-taking and for the construction of strategies to minimize thermal discomfort.
