A PREDICTIVE MODEL FOR OZONE UPLIFTING IN OBSTRUCTION PRONE ENVIRONMENT

A model for predicting uplifting of ozone gas in obstruction prone areas is developed. The model is dependent on ground level temperature, four metre height temperature, wind speed and solar radiationand the obstruction used in this research is an existing four metre fence wall. With data points established both inside and outside the fence wall, and four metre height above the ground level of the inside and outside positions, data were collected for five days at two hour intervals. The Buckingham’s π-method of dimensional analysis was adopted to develop this model and collated field measurements were used to calibrate the model through regression. Results show that the model developed for Ozone uplifting attained a correlation coefficient of 0.996.Verification of the model showed a correlation coefficient of 0.905 and a mean square error (MSE) of 0.0007 between the predicted and observed ozone concentration.
