Empirical—statistical models ate based on estabUshing a relationship between historically observed air quaUty and the corresponding emissions. The linear rollback model is simple to use and requites few data, and for these reasons has been widely appHed (3,4). Linear rollback models assume that the highest measured pollutant concentration is proportional to the basinwide emission rate, plus the background value that is,... 

Rollback Both linear rollback and modified rollback models were used by Barth to examine federal motor-vehicle goals for standards governing carbon monoxide, hydrocarbon, and oxides of nitrogen. The linear rollback principle was suggested and applied to these primary pollutants ... 

Eschenroeder" compared linear rollback results with photochemical-diffusion model results in assessing the effects of various stages of the... 

A number of different approaches have been taken to understanding the VOC-NO chemistry and its application to control strategy developments. These include the use of environmental chambers, models ranging from simple linear rollback to complex Eulerian models, and field studies. 

The rollback approach assumes that emissions and atmospheric concentrations are linearly related, i.e., that a given percentage reduction in emission will result in a similar percentage reduction in atmospheric concentrations. This is most likely a valid assumption for a nonreactive gas such as carbon monoxide, whose principal source is the automobile. The model is...
