SELECTED OBSERVATIONS ON MESOSCALE MODELING

The mesocale simulation model for inert pollutants is defined, the objectives of mesocale modeling are set forth, the purposes of such modeling are stated, and attention is directed toward the evaluation and improvement of mesoscale carbon monoxide (CO) models of 8-hour concentrations, and the improvement of model versatility and resolution. The objectives of mesocale modeling relate to the prediction of absolute pollutant concentration, the prediction of relative changes in pollutant concentration, and a combination of the first and second objectives. Mesocale modeling may be utilized for short-term forecasting, impact assessment of new emission sources, and impact assessment of changes to existing emission sources. Model versatility and resolution improvements are desirable in the areas of meteorology, emission rates, traffic data, and microscale submodels. Improvements are also desirable in user documentation such as user manuals. Most mesoscale CO models are relatively inexpensive to operate, but cost is a major factor when poor meteorological or traffic input data are used.
