The table below lists the dates of the upcoming Introduction to CMAQ classes along with the enrollment status in each class. When enrollment is full (15 registered students) we will no longer accept applications for the class and the status column in the table will display that the class is full.

The class is subject to cancellation if there are not enough registered students. A minimum of 6 trainees must be registered to conduct a training.

The Introduction to CMAQ course can also be conducted off site, provided that appropriate facilities are available and there are an adequate number of interested students. Email cmas@unc.edu to inquire about off-site trainings.

About the Course

Introduction to CMAQ is a 2-day course that uses lectures and hands-on computer exercises to teach students how to run the CMAQ programs and examine input and output files from the software. The class covers topics including CMAQ terminology, how to set up and reconfigure different modeling domains, nested simulations, and multi-day simulations. Problem-solving exercises challenge the students to integrate the lessons that they had previously learned in the class to complete more advanced modeling tasks.

The syllabus is shown below to highlight the range of topics covered during the course. The course starts with a lecture on the basics of CMAQ, including an overview of air quality modeling, an introduction to the CMAQ programs, and a description of the course structure. The Hands-on laboratories have each student working on a computer pre-loaded with the course training materials. The labs focus on configuring and building the CMAQ programs, examining the input and output files, and running the programs to give students practical experience using CMAQ. The advanced topics lecture during day 2 of the training provides an overview of modeling diagnostic and evaluation topics, such as sensitivity modeling and statistical performance evaluation. The class concludes with a problem solving lab that emulates a real-world modeling task. The students are presented with a set of modeling data and a brief description of the modeling task. Where the previous labs included step-by-step instructions on how to set up and run the different CMAQ programs, in the Problem Solving Case Study each student is challenged to run CMAQ with help from the lessons learned in the previous labs, the instructor, and their fellow students.

At the completion of this course, students will be able to download, configure, compile, and run the CMAQ programs. They will possess the knowledge and practical experience needed to prepare input files for CMAQ and to produce CMAQ output.

Prerequisites

A basic knowledge of air quality modeling concepts will help students to get the most out of this course. The course covers air quality terminology and very basic general air quality concepts, but the focus is mostly on the operational details of CMAQ. A background in air quality will provide context for the need for gridded air quality models.

Knowledge of the Linux command line language and the C-shell are also prerequisites for this course. Students with a working understanding of navigating Linux directory structures, viewing/editing text files, and executing commands from a Linux command prompt will benefit more from this class than students with no Linux experience.
