Abstract
Ground-level ozone (O‚) has a significant effect on human health when the concentration level exceeds Malaysia Ambient Air Quality Guidelines (MAAQG). This research focuses on daytime ground-level O‚ concentrations in Kemaman Terengganu. The aim of this study is to compare the performance of the multiple linear regression model and the feed forward backpropagation neural network model for predicting daytime O‚ concentrations. This study used hourly average monitoring records from 2009 to 2012. Five performance indicators that are normalized absolute error (NAE) root mean squared error (RMSE) index of agreement (IA) prediction accuracy (PA) and coefficient of determination (R ) were used to evaluate the models performances. The feed forward backpropagation neural network model shows better performances with smaller calculated errors (NAE 0.1729 RMSE 6.7906) and high accuracy (IA 0.9427 PA 0.8054 R 0.8022) than the multiple linear regression. The performances of feed forward backpropagation neural network model can be used for O‚ concentration prediction in the future.
