             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.",
