%X Air quality status on the East Coast of Peninsular Malaysia is dominated by Particulate Matter (PM 10) throughout the years. Studies have affirmed that PM 10 influence human health and the environment. Therefore, precise forecasting algorithms are urgently needed to determine the PM 10 status for mitigation plan and early warning purposes. This study investigates the forecasting performance of a linear (Multiple Linear Regression) and two non-linear models (Multi-Layer Perceptron and Radial Basis Function) utilizing meteorological and gaseous pollutants variables as input parameters from the year 2000¨C2014 at four sites with different surrounding activities of urban, sub-urban and rural areas. Non-linear model (Radial Basis Function) outperforms the linear model with the error reduced by 78.9% (urban), 32.1% (sub-urban) and 39.8% (rural). Association between PM 10 and its contributing factors are complex and non-linear in nature, best captured by an Artificial Neural Network, which generates more accurate PM 10 compared to the linear model. The results are robust enough for precise next day forecasting of PM 10 concentration on the East Coast of Peninsular Malaysia. View Full-Tex
