Abstract: This paper investigates the potential for developing schemes that classify convective and stratiform precipitation areas using the high infrared spectral resolution of the SEVIRI sensor (Spinning Enhanced Visible and Infrared Imager). It is a technique based on neural network (NN) using information about optical and microphysical cloud properties from SEVIRI. The nonparametric NN approach approximates the best nonlinear function between multispectral information about pixel derived from MSG satellite data and rain information from radar data to classify convective and stratiform rain. The neural network developed here accepts SEVIRI data as input and radar data as output data that are in spatiotemporal coincidence. The results show that the quality of information used from the SEVIRI sensor and the use of Multilayer architecture percepetron with two hidden layers were used to provide a good classification.
