Abstract |
Models-3/CMAQ model is designed as a multi-pollutant Eularian grid regional to urban scale air quality and atmospheric deposition modeling system. The release version of Models-3/CMAQ will feature science options available to the user including the gas phase chemistry mechanisms, RADM2, and CB-IV a set of chemistry solvers, options for horizontal and vertical advection schemes, algorithms for fine and coarse particulate matter, photolysis rates and a plume-in-grid approach. These current science options are discussed in the context of the overall structure of Models-3/CMAQ model which includes an emission and meteorological preprocessors linked to the CMAQ by interface processors. Also discussed are the methods to determine and test the relative contribution of different atmospheric processes to the air quality predictions, important functions built into the CMAQ system. |
