abstract = "The synergistic use of different sensors for the observation of
precipitation is an approach of growing importance, worldwidely.
In particular, the combination of weather radar and environmental
satellite data is used in many important applications, e.g.
hydrological management and agricultural practices. The
understanding of the correlation of precipitating structures
observed in both images allows to validate forecasts based only on
satellites images when radars are not available. In Brazil,
multi-purpose observation of precipitation dates back to 1974,
when a C-band non-coherent weather radar started operations at
Bauru (lat 22°2130 S, long 49°142 W), in the central area of the
State of S{\~a}o Paulo. In 1992, a S-band Doppler system (thereon
BRU) replaced the old C-band, enhancing substantially the
potential for applications, in addition to broadening the research
perspectives, mainly those focused on precipitation. In 1994, a
second radar was installed in the West, at Presidente Prudente
(lat 22°1030 S, long 51°2230) in network with the Bauru radar,
largely increasing the area covered by radar in the state and
adjacent regions. Both radars have recently undergone a
substantial upgrade/update which significantly improved the
quality of the rainfall measurements. BRU, in special, covers one
of the most socio-economically important regions of the country,
providing crucial support to Civil Defence and being extensively
explored by the productive sector. Economic constraints preventing
the deployment of a dense network resulted in the use of BRU to
the outer radar ranges. The degradation of radar observation at
those ranges prompted the developments of procedures to use
satellite data jointly with the radar. Calheiros and DOliveira
(2007) proposed a methodology to complement the far range radar
observations with satellite radiometric data, in an attempt to
extend the useful range of the radar.",
