SURFACE TEMPERATURE IN RESPONSE TO CHANGES IN COVERAGE AND DUE TO LAND USE URBAN EXPANSION: A STUDY IN BRASILIA-DF

Lidiane Cristina Félix Gomes

Abstract


The objective of this study was to evaluate the dynamics of temperature of the land surface and land use through TM-Landsat 5 images, between 1987 and 2011 in Metropolitan Brasilia, the Federal District. The city was chosen to present quite peculiar characteristics resulting from its urban planning, including as regards its location, and that over the years has been modified due to the new trends in occupation of its territory. Satellite images were used Landsat 5-TM and SEBAL. The results indicated that the expansion of urban areas has contributed to a significant increase in temperatures over the years, but in the Pilot Plan, it was revealed that there was a cooling mostly derived from the implementation of wooded medians. In impermeable areas, the temperatures approached 30°C and was verified environments conducive to formation of urban heat islands.
