Sub-daily rainfall datasets are not commonly available in developing countries, but the annual maximum daily rainfall ( P ma) often is. This article evaluates the ratio between 1440 min of rainfall and the  P ma, as well as the sub-daily rainfall ratio from different origins as disaggregation coefficients for modeling the intensity-duration-frequency ( IDF ) curves in the metropolitan area of Belo Horizonte, Brazil. Non-parametric tests were previously applied to the series to verify stationarity, homogeneity, randomness, and independence. It was verified via Student’s t-test and identity test models that there is a significant difference between the  IDF  curves from the sub-daily rainfall dataset and disaggregation rainfall dataset. Nevertheless, the model performance indexes between the results of  IDF  curves indicate the errors are acceptable, thus guaranteeing an alternative tool in places where there are no sub-daily rainfall datasets available. Sub-daily rainfall ratios can be used as disaggregation coefficients on a local and regional scale.
