Resumo: The Metropolitan Area of Rio de Janeiro (MARJ) presents a number of environmental problems, among them, the occurrence of Urban Heat Islands (UHI). This paper examines the characteristics of the UHI in the MARJ. For such, 8-days compositions data of Land Surface Temperature (LST), during the period from January 2003 to December 2010, generated by the MODIS (Moderate-resolution Imaging Spectroradiometer) sensor, aboard the Terra and Aqua satellites were used. The data analysis was done by calculating the average LST gathering data for the satellites pass over the seasons, so it could be analyzed more clearly, without cloud contamination. It was observed, some zones presented temperatures close to 50ºC during the spring and summer. Throughout the autumn and winter the average reached 40 º C over most of the study area. During the spring, a 25ºC temperature range was registered between areas with different urbanization levels. In the summer the amplitude was 20ºC between the same areas. In autumn the difference was 15ºC and in winter, 10ºC.

Para tal, foram usadas composições de 8 dias de dados de Temperatura Superficial Continental (TSC) geradas pelo sensor MODIS (Moderate-resolution Imaging Spectroradiometer) a bordo dos satélites Aqua e Terra no período de janeiro de 2003 a dezembro de 2010. A análise foi feita agrupando-se os dados para as diferentes estações do ano e posteriormente calculando-se a média de TSC para cada estação com o intuito de verificar a variação sazonal da ICU. Observou-se que, algumas zonas apresentaram temperaturas próximas dos 50ºC durante a primavera e o verão. Ao longo do outono e do inverno as médias atingiram 40ºC sobre a maior parte da região de estudo. Foram registradas amplitudes térmicas de até 25ºC entre áreas com diferentes níveis de urbanização, durante a primavera. No verão a amplitude foi de 20ºC entre as mesmas áreas. No outono a diferença foi de 15ºC e no inverno, de 10ºC.Universidade Federal do Rio de Janeiro2017-02-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufrj.br/index.php/aigeo/article/view/782710.11137/2014_2_111_122Anuário do Instituto de Geociências; Vol 37, No 2 (2014); 111-122Anuário do Instituto de Geociências; Vol 37, No 2 (2014); 111-1221982-39080101-9759reponame:Anuário do Instituto de Geociências (Online)instname:Universidade Federal do Rio de Janeiro (UFRJ)instacron:UFRJporhttps://revistas.ufrj.br/index.php/aigeo/article/view/7827/6308Copyright (c) 2014 Anuário do Instituto de Geociênciashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSena, Caio Atila PereiraFrança, José Ricardo de AlmeidaPeres, Leonardo Faria2017-02-15T17:28:22Zoai:www.revistas.ufrj.br:article/7827Revistahttps://revistas.ufrj.br/index.php/aigeo/indexPUBhttps://revistas.ufrj.br/index.php/aigeo/oaianuario@igeo.ufrj.br||1982-39080101-9759opendoar:2017-02-15T17:28:22Anuário do Instituto de Geociências (Online) - Universidade Federal do Rio de Janeiro (UFRJ)false
