Part of the Air Pollution Problems Series book series (AIRPP)
The assumption of proportionality between emissions and air quality (ambient concentration) leads directly to the long-term simple box model, which is source oriented. The independent variable (input) for the box model is the source strength, and its output is the concentration value. However, if we use a past or present measured concentration as input and investigate the changes in source strength in order to find some other concentration (the desired air quality), we arrive at the receptor-oriented symmetrical counterpart of the box model which is called the rollback model or proportional scaling model.where R is the percentage reduction required, xa the measured concentration, xb the background concentration and xc the desired air quality.
