The first generation U.S. Environmental Protection Agency Regional Oxidant Model (ROM1) has been tested and evaluated for O3 predictions on a two-day test case episode in the northeast U.S. during 3-4 August 1979. The period was characterized by relatively high O3 concentrations in the southern Great Lakes area where clear skies persisted. The highest observed hour-average O3 level monitored at a surface site during the period was 159 ppb. The ROM1 incorporates some simplifying assumptions and algorithms as compared to the second generation version, ROM2, which is in preliminary testing stages now and will eventually become the production version of the model. Evaluation results for the test episode showed that the ROM1 had approximately a 6% average underprediction of O3 when all hours and surface monitoring sites were considered.
