EPA third-generation air quality modeling system: Models-3 user manual. Standard tutorial
Models-3 is a flexible software system designed to simplify the development and use of environmental assessment and other decision support tools. It is designed for applications ranging from regulatory and policy analysis to understanding the complex interactions of atmospheric chemistry and physics. The initial version of Models-3 contains a Community Multi-scale Air Quality (CMAQ) modeling system for urban to regional scale air quality simulation of tropospheric ozone, acid deposition, visibility, and fine particles. Models-3 and CMAQ in combination form a powerful third generation air quality modeling and assessment system that enables a user to execute air quality simulation models and visualize their results. Models-3/CMAQ also assists the model developer to assemble, test, and evaluate science process components and their impact on chemistry-transport model predictions by facilitating the interchange of science codes, transparent use of multiple computing platforms, and access of data across the network. The Models-3/CMAQ provides flexibility to change key model specifications such as grid resolution and chemistry mechanism without rewriting the code. Models-3/CMAQ is intended to serve as a community framework for continual advancement and use of environmental assessment tools. This User Manual Tutorial serves as a guide to show the steps necessary to implement an application in Models-3/CMAQ.
