Neste trabalho foi analisada a utilização de estimativas de precipitação geradas pelo satélite TRMM como variável de entrada em um modelo hidrológico semidistribuído, o Slurp. Para tal, foram utilizados dados diários de temperatura do ar, temperatura do ponto de orvalho e umidade relativa do ar, oriundos de estações meteorológicas; dados de cobertura do solo, derivados de imagens LandSat 5; dados fluviométricos diários e; dados do produto 3B42, com resolução temporal de 3 horas e espacial de 2,5 km. Os resultados indicam que o modelo foi adequado ao simular a vazão na bacia do rio Jamari, com R2 de 0,82. Com relação às vazões média, máxima e mínima, os resultados foram coerentes com de outros autores que utilizaram precipitação na superfície. O método de calibração do modelo mostrou-se hábil, mesmo na falta de alguns parâmetros, indicando que os resultados podem ser ainda melhores.Downloads
