Introduction

The Community Multiscale Air Quality (CMAQ) modeling system is at the heart of the third-generation air quality modeling system (Models-3) developed by the U.S. Environmental Protections Agency (USEPA). It is a three-dimensional Euler grid-based atmospheric chemistry and transmission simulation system to provide sound estimates of ozone, particulates, toxics, and acid deposition. The CMAQ model comprehensively represents air quality problems at different spatial scales and is widely used to address environmental issues and to conduct atmospheric research.

Programming language: Fortran
