Abstract

AMORIM, Margarete Cristiane de Costa Trindade. Remote sensing of surface heat islands: Examples of small- and medium-sized cities in the tropical environment, Brazil. Finisterra [online]. 2017, n.105, pp.111-133. ISSN 0430-5027.  https://doi.org/10.18055/Finis6888.

The purpose of this article is to identify how island surface heat is spatialized in small- and medium-sized cities through the use of images of the thermal infrared channel of the Landsat 8 satellite. It thus intends to assess the characteristics of surface temperatures and the spatial distribution of woody vegetation, construction density and the types of rooftop materials in small- and medium-sized cities in a tropical environment. We diagnosed surface heat islands of strong magnitude (8-11°C), and the areas with the highest temperatures were associated with construction materials used in rooftops, particularly asbestos cement and zinc, construction density and lack of woody vegetation

Keywords : Urban climate; surface heat island; Landsat 8; remote sensing; tropical cities.
