APPLICATION OF THE MODELS-3 COMMUNITY MULTI-SCALE AIR QUALITY (CMAQ) MODEL SYSTEM TO SOS/NASHVILLE 1999

摘要

The Models-3 Community Multi-scale Air Quality (CMAQ) model, first released by the USEPA in 1999 (Byun and Ching 1999), continues to be developed and evaluated. The principal components of the CMAQ system include a comprehensive emission processor known as the Sparse Matrix Operator Kernel for Emissions (SMOKE), a Chemical Transport Model (CTM), and a meteorology model, the Penn State/NCAR Mesoscale Model (MM5). Evaluation of the CMAQ modeling system includes simulation of a series of air quality field studies such as NARSTO and SOS. This paper describes many upgrades to the next release (June 2002) of the CMAQ system and our initial model application to the SOS/Nashville 1999 field experiment.
