                         operational forecasting by means of an appropriated combination 
                         between observational data and data from a mathematical model. In 
                         the present work data assimilation methods based on Kalman filter 
                         and artificial neural networks are applied to a three-wave model 
                         of auroral radio emissions. A novel data assimilation method is 
                         presented, whereby a multilayer perceptron neural network is 
                         trained to emulate a Kalman filter for data assimilation by using 
                         cross validation. The results obtained render support for the use 
                         of neural networks as an assimilation technique for space weather
