abstract = "Satellite rainfall estimates (SRFE) are a promising alternative
for the lack of reliable, densely distributed, precipitation data
common in developing countries and remote locations. SRFE may be
significantly improved when corrected based on rain gauge data. In
the present study the first complete validation of the Tropical
Rainfall Measuring Mission (TRMM) 3B42-based MERGE product is
performed by means of ground truthing and hydrological
modeling-based applications. Four distinct, highly anthropogenic
watersheds were selected in the Upper Para{\'{\i}}ba do Sul
River Basin (UPSRB)Brazil. The results show that when compared to
TRMM Multi-Satellite Precipitation Analysis (TMPA) 3B42V7 at the
watershed scale, MERGE has a higher correlation with observed
data. Likewise, root mean square errors and bias are significantly
lower for MERGE products. When hydrologically validated,
MERGE-based streamflow simulations have shown the capacity of
reproducing the overall hydrological regime with good to very good
results for the downstream lowland sections. Limitations were
observed in the hydrological modeling of the upstream, highly
anthropogenic, dammed watersheds. However, such limitations may
not be attributed to MERGE precipitation since they were also
obtained for the individually calibrated rain gauge-based
simulations. The results indicate that the used MERGE dataset as a
hydrological model input is better suited for application in the
UPSRB than the TMPA 3B42V7.",
