Resumo: | The present study aimed to analyze the behavior of the Monte Alegre Formula (MAF) and to quantify the heat focus detected by reference satellites, comparing them with the fires that occurred in Chapada dos Guimarães National Park from 2007 to 2015. Heat analysis was performed using images from AQUA, TERRA and NOAA satellites, whose daily data of detected foci were used to compose the time series over the years, allowing the analysis of trends in the numbers of foci for the park. The data were acquired in the platform of the National Institute of Space Research, in the historical data base of the National Institute of Meteorology and by to the manager of the park. In most years there was an overestimation of the number of heat sources in relation to the number of fire occurrences. The TERRA satellite presented values were closer to the number of fire records in the park. It was observed that 87.69% of the fires were validated in relation to MAF, where 60% belonged to very high hazard class and 27.69% were classified in the high hazard class, demonstrating the effectiveness of MAF in relation to records of fires occurring in the park. |

O monitoramento dos focos de calor foi realizado através de imagens dos satélites AQUA, TERRA e NOAA, cujos dados diários de focos detectados foram usados para compor a série temporal ao longo dos anos, permitindo a análise de tendências dos números de focos para o parque. Os dados foram adquiridos na plataforma do Instituto Nacional de Pesquisas Espaciais, na base de dados históricos do Instituto Nacional de Meteorologia e junto à gerência do parque. Na maioria dos anos houve uma superestimação do número de focos de calor em relação ao número de ocorrência dos incêndios. O satélite TERRA apresentou valores que mais se aproximaram do número de registros de fogo no parque. Observou-se que 87,69% dos incêndios foram validados em relação a FMA, onde 60% estavam na classe de perigo muito alto e 27,69% enquadraram-se na classe de perigo alto, demonstrando a efetividade da FMA em relação aos registros de incêndios ocorridos no parque.Embrapa Florestas2017-12-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/vnd.ms-excelhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/144010.4336/2017.pfb.37.92.1440Pesquisa Florestal Brasileira; v. 37 n. 92 (2017): out./dez.; 535-543Pesquisa Florestal Brasileira; Vol. 37 No. 92 (2017): out./dez.; 535-5431983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1440/620https://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1440/1472Machado Neto, Arlindo de PaulaBatista, Antonio CarlosSoares, Ronaldo VianaBiondi, Danielade Morais, Riubi Lopesinfo:eu-repo/semantics/openAccess2019-01-02T18:39:23Zoai:pfb.cnpf.embrapa.br/pfb:article/1440Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2019-01-02T18:39:23Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
