abstract = "Rainfall estimation from satellite data have many applications in
climatology and meteorology but calculation associated requires a
rapid processing to large amount of data in order to achieve
significant result. The neural networks (NN)method is one of the
several techniques employed to extract meteorologically-useful
information from remotely sensed data. However this method is
hardly used independently to yield quasi-real time rainfall
estimates since a large amount os satellite data are needed to
generate the input/output data for the NN training. In order to
overcome this shortage, multiresolution wavelet transform
(WT)technique is proposed to decompose the images to obtain the
key information for further analysis. As a result, the NN training
becomes easier and faster. In the paper a case study to estimate
rainfall over the central part of S{\~a}o Paulo state, Brazil
using both the NN and WT techniques is given. The analyses were
performed using GOES-8 brightness temperature data and
meteorological radar data from Bauru, SP. It is concluded that NN
can be successfully used to estimate rainfall from remotely sensed
imagery.",
