Resumo: The rapid and disordered urban growth generated an artificial geographic environment and low environmental health, characterized by the expansion of peripheral and central areas. The transformations in land use and occupation generate changes in the energy balance and atmosphere, resulting in the heating of cities. Therefore, the objective of this article is to analyze the Earth's Surface Temperature (TST) and relate with vegetation cover through the Normalized Difference Vegetation Index (NDVI) in the city of Fortaleza, Ceará. Initially, orbital images, OLI (Operational Land Imager) and TIRS10 (Thermal Infrared Sensor) of landsat-8 were obited in the United States Geological Survey (USGS) – orbit 217 and point 62. The images chosen for this study are from 02/08/2013 and 26/08/2016. It was verified the direct relationship of biomass vigor (NDVI) and urbanization with surface temperature values and urban heat islands. The environments with the lowest NDVI values, with the exception of aquatic bodies, presented higher temperature values, exposing the importance of vegetation in the microclimate.

Las transformaciones en el uso de la tierra y la ocupación generan cambios en el equilibrio energético y la atmósfera, lo que resulta en el calentamiento de las ciudades. Por lo tanto, el objetivo de este artículo es analizar la Temperatura superficial de la Tierra (TST) y relacionarse con la cobertura vegetal a través del índice de vegetación de diferencia normalizada (NDVI) en la ciudad de Fortaleza, Ceará. Inicialmente, las imágenes orbitales, OLI (Operational Land Imager) y TIRS10 (Thermal Infrared Sensor) de landsat-8 fueron obituadas en el Servicio Geológico de los Estados Unidos (USGS) – órbita 217 y punto 62. Las imágenes elegidas para este estudio son del 02/08/2013 y del 26/08/2016. Se verificó la relación directa del vigor de la biomasa (NDVI) y la urbanización con los valores de temperatura superficial y las islas de calor urbanas. Los ambientes con los valores NDVI más bajos, con la excepción de los cuerpos acuáticos, presentaron valores de temperatura más altos, exponiendo la importancia de la vegetación en el microclima.O rápido e desordenado crescimento urbano gerou um meio geográfico artificial e de baixa salubridade ambiental, caracterizado pela expansão de áreas periféricas e centrais. As transformações no uso e ocupação do solo geram mudanças no balanço de energia e na atmosfera, resultando no aquecimento das cidades. Portanto, o objetivo desse artigo é analisar a Temperatura de Superfície Terrestre (TST) e relacionar com cobertura vegetal por meio do Índice de Vegetação por Diferença Normalizada (NDVI) no município de Fortaleza, Ceará. Inicialmente foram obitidas as imagens orbitais, sensores OLI, (Operational Land Imager) e TIRS10 (Thermal Infrared Sensor) do Landsat-8 em United States Geological Survey (USGS) – órbita 217 e ponto 62. As imagens escolhidas para esse estudo é de 02/08/2013 e 26/08/2016. Verificou-se a relação direta do vigor da biomassa (NDVI) e da urbanização com valores de temperatura de superfície e as ilhas de calor urbano. Os ambientes que apresentaram menores valores de NDVI, com exceção os corpos aquáticos, apresentaram maiores valores de temperatura, expondo a importância da vegetação no microclima.Research, Society and Development2020-04-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/373110.33448/rsd-v9i7.3731Research, Society and Development; Vol. 9 No. 7; e57973731Research, Society and Development; Vol. 9 Núm. 7; e57973731Research, Society and Development; v. 9 n. 7; e579737312525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/3731/2856Copyright (c) 2020 Eliezio Nascimento Barboza, Francisco das Chagas Bezerra Neto, Clarice Ribeiro Alves Caianainfo:eu-repo/semantics/openAccessBarboza, Eliezio NascimentoBezerra Neto, Francisco das ChagasCaiana, Clarice Ribeiro Alves2020-08-20T18:05:03Zoai:ojs.pkp.sfu.ca:article/3731Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:27:50.019490Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
