Abstract

The present study attempts to model ambient ozone (O3) concentrations using the Feed-forward backpropagation neural network model as a function of meteorological conditions and to draw a map of ozone concentrations over the Agadir City and its neighboring regions. The data, used to train the network, was collected during a period of 30 days in Agadir City using a mobile monitoring station. The data was divided into two sets: 85% for the training and 15% for the testing. Different neural network architectures were tested during the training process. A network of two hidden layers with a [7-16-16-1] structure, Levenberg-Marquardt as a training algorithm and log-sigmoid as a transfer function was found to give the best predictions for both the training and testing data. Statistical agreement between predicted and observed values is evaluated by coefficient of correlation (CC), root mean square error (RMSE) and mean absolute error (MAE). Results show that artificial neural network modelling appears to be a promising method for modelling air-pollution. IDW Inverse distance method was used in order to interpolate the ozone concentrations over the city of Agadir and its neighboring areas.
