| Abstract | Rainfall estimation from satellite data have many applications in climatological and meteorological studies. Their calculation requires a rapid processing of large amounts of data in order to achieve the desired result. The Neural Networks (NN) method is one of the several techniques employed to extract meteorologically useful information from remote sensing data. However this method is hardly used by itself to yield quasi-real time rainfall estimates once this demands a large amount of satellite data to generate the input/output data for the NN training. In order to overcome this, we propose to use Multiresolution Wavelet Transform (WT) technique to decompose the images retaining only the key information for the current problem. As a result, the NN training becomes easier and faster. We propose in this study to estimate rainfall over the central part of the São Paulo state, Brazil using both the NN and WT techniques. The analyses were performed using GOES-8 brightness temperature and meteorological radar data from Bauru, SP. The results suggest that NN can successfully estimate rainfall from remote sensing imagery. |
