Validação Da Precipitação Estimada Pelo Produto 3b42 Do Satélite “Tropical Rainfall Measuring Mission” Para a Sub-Bacia Hidrográfica Paraíba Do Sul, Estado De São Paulo, Brasil

Abstract: O monitoramento hidrológico em bacias hidrográficas se faz necessário para prevenir e mitigar danos provocados por precipitações, porém, quando este é realizado por meio de observações em campo possui limitações, como: não cobrir todo o território brasileiro, a necessidade de técnicos para operação e estar sujeito à falha de dados em séries históricas. Para suprir a crescente demanda por monitoramento, surgiu o satélite Tropical Rainfall Measuring Mission (TRMM), capaz de monitorar variáveis hidrológicas, como… Show more

“…For the validation of the rainfall predicted by ANN, the following statistical indicators were calculated as in Silva et al (2021): Pearson's linear correlation coefficient (r), mean absolute error (MAE) and bias (b). In order to identify the season in which the largest errors occurred, besides their tendency to underestimate or overestimate, the mean absolute error and bias were calculated separately for the rainy season (October to March) and dry season (April to September).…”
