Photochemical grid models must be used in the US to demonstrate that emissions control policies will result in compliance with the National Ambient Air Quality Standard (NAAQS) for ozone (O{sub 3}). Because ozone is a secondary pollutant formed as a result of photochemical reactions involving primary pollutants such as volatile organic compounds (VOCs) and nitrogen oxides (NO{sub x}), the emission control strategies are not intuitively obvious and depend on the use of well-defined and well-evaluated photochemical grid models. The Cooperative Regional Model Evaluation (CReME) project is concerned with the evaluation of several widely-used photochemical grid models on three regional domains. This paper describes the evaluations on the Lake Michigan Ozone Study (LMOS) domain. The goals are to evaluate the performance of the models, to diagnose the reasons for certain characteristics of the models` performance, and to carry out sensitivity runs in which NO{sub x} and VOC emissions are reduced by set amounts.
