abstract = "The main objective of this study was to evaluate the monthly mean
areal rainfall estimated using the Tropical Rainfall Measuring
Mission (TRMM) 3B43 version 7 product over an inland area in
Central Brazil. Furthermore, we investigated the effect of TRMM
orbit boost (in August 2001) over the 3B43 estimates. The TRMM
3B43 estimates were compared to reference rainfall data, collected
at 67 rain gauge stations irregularly distributed in the study
area. The results showed a good agreement between the TRMM 3B43
areal monthly mean rainfall estimations and reference data (r >
0.97). The error analysis showed that the TRMM 3B43 product tends
to overestimate the areal monthly mean rainfall at approximately
1.24%. The root-mean-square error (RMSE) for the entire period was
19.66 mmmonth-1 (15.75%). A Monte Carlo simulation and Wilcoxon
statistical test showed that the RMSE increased significantly
(p-value <0.01) after the boost, rising from 15.20 to 23.06
mmmonth -1. However, the increase in the RMSE does not preclude
the use of the TRMM 3B43 product for estimating the monthly mean
areal rainfall over the Upper Paran{\'a} watershed. The impacts
of boost on TRMM 3B43 estimates were observed only for rainfall
rates higher than 250 mmmonth-1. © 2014 SPIE.",
