Abstract
The Integrated Empirical Rate (IER) model is used as an airshed photochemical management tool, owing to its simplicity and accuracy, to give an understanding of the degree of photooxidation that is occurring in air parcels. The model requires a knowledge of concentrations of NO, NOy, ozone and reactive organic compounds (ROC) to estimate the reactivity of an air parcel. All these are measured by Airtrak, an instrument designed specifically to provide data for the IER model. However, as the majority of air quality agencies do not have access to this technology, most conventional air quality data consists only of NO, NOy and ozone. In this paper, the IER model has been applied successfully to conventional data by assuming a constant ratio of ROC to NOx emissions, which can be determined from emissions inventories or Airtrak technology if available. The proposed method is illustrated by means of an example, which provides insight into the requirements, restrictions and effectiveness of this modelling technique.
