abstract = "In an attempt to validate the Tropical Rainfall Measuring Mission
(TRMM) precipitation radar (PR) over Brazil, TRMM PR estimates are
compared with rain gauge station data from Agencia Nacional de
Energia Eletrica (ANEEL). The analysis is conducted on a seasonal
basis and considers five geographic regions with different
precipitation regimes. The results showed that TRMM PR seasonal
rainfall is well correlated with ANEEL rainfall (correlation
coefficients are significant at the 99% confidence level) over
most of Brazil. The random and systematic errors of TRMM PR are
sensitive to seasonal and regional differences. During December to
February and March to May, TRMM PR rainfall is reliable over
Brazil. In June to August (September to November) TRMM PR
estimates are only reliable in the Amazonian and southern
(Amazonian and southeastern) regions. In the other regions the
relative RMS errors are larger than 50%, indicating that the
random errors are high.",
