“…In fact, in many situations, the spatial distribution of rainfall was not properly described by the IMERG satellite retrievals, with a tendency of generating smoother surfaces as compared to the data captured by ground-based information. Nonetheless, as may be inferred from Melo et al, 2015, and Moraes and Gonçalves, 2021 [29,35], the IMERG-GPM may be a preferable alternative for our study region after spatial averaging, as it more properly described the rainfall amounts on a daily time scale. Hence, despite the inaccurate descriptions of daily rainfall extremes, which are not considerably improved under bias correction [6], the short size of our sample, and the relatively poor representation of spatial patterns, we still believe that the IMERG-GPM product may be a useful data source for the Brazilian midwestern region, as compared to well-established alternatives such as TRMM, mainly for continuous rainfall-runoff simulation based on a daily time step, and drought management, which requires data at monthly or longer time scales.…”
