1.3. Features of CMAQ for Application Users

CMAQ is designed to address the complex interactions among multiple air quality issues simultaneously. Using a one-atmosphere approach to air quality modeling by applying multiscale and multi-pollutant modeling techniques, CMAQ can provide independent but dynamically consistent predictions of several different pollutants at varying spatial scales. The modularity of the CMAQ design provides an unprecedented level of flexibility in air quality model configuration for optimizing model performance for different applications and spatial resolutions. In addition to the flexibility of the one-atmosphere approach, CMAQ provides the following features to users interested in applying the model for research or regulatory applications:
