Avaliação de modelos globais do geopotencial para os estados do Maranhão e Piauí

Abstract: A avaliação do modelo geoidal oficial do Brasil, o MAPGEO2010, mostra que suas menores resoluções situam-se nos estados do Maranhão e do Piauí, com discrepâncias variando de cerca de ±1 m em 500 km. Justamente, em tal região se faz necessário um melhor modelo geoidal em vista das limitações de informações geodésicas existentes. Com base no problema evidenciado na região destacada, buscou-se avaliar o comportamento das alturas geoidais oriundas de alguns Modelos Globais do Geopotencial MGGs. Foram utilizados co… Show more
