Transformation of nitrogen dioxide into ozone and prediction of ozone concentrations using multiple linear regression techniques

摘要

Analysis and forecasting of air quality parameters are important topics of atmospheric and environmental research today due to the health impact caused by air pollution. This study examines transformation of nitrogen dioxide (NO_2) into ozone (O_3) at urban environment using time series plot. Data on the concentration of environmental pollutants and meteorological variables were employed to predict the concentration of O_3 in the atmosphere. Possibility of employing multiple linear regression models as a tool for prediction of O_3 concentration was tested. Results indicated that the presence of NO_2 and sunshine influence the concentration of O_3 in Malaysia. The influence of the previous hour ozone on the next hour concentrations was also demonstrated.
