Community Multiscale Air Quality Modeling System (CMAQ)

Opportunities for CMAQ Collaborators

Contribute to the CMAQ System

As a public domain model, CMAQ is the product of contributions from many developers, whose numbers are only expected to increase with the number of users worldwide.  The EPA uses the version control system git to manage the cross-community access to this software.

Work with Us

Opportunities for students and postdoctoral fellows to work with our team are available through three mechanisms:
Groupwork being performed by CMAQ team members

ORISE and NAS positions are available throughout the year while NERL postdoc positions are advertised once a year.

The CMAQ research team also welcomes the opportunity to host visiting scientists interested in the development, application, and evaluation of CMAQ and related models. Visiting scientists fall into one of two categories:

  1. Visitors
  2. Guest Scientists


Visitors travel to EPA/RTP for a day or two to meet with individuals on the CMAQ team. A seminar can also be scheduled and is encouraged if you’re interested in sharing a presentation on your research. Requests for visits should be made at least a week in advance.

Guest Scientist

Researchers interested in establishing an on-site collaboration with the CMAQ research team in Research Triangle Park, NC, and traveling to EPA/RTP as an unpaid Guest Scientist should contact a member of the CMAQ research team to potentially serve as the Guest Scientist’s host. Accommodated requests shall primarily benefit the Guest Scientist and/or his/her affiliated organization and be in the public interest. These benefits would either advance the science related to CMAQ and/or increase the Guest Scientist’s knowledge and expertise related to CMAQ.

A written request from the Guest Scientist must either:

  1. contain distinct and attainable objectives to conduct a research project; or
  2. request training for the individual.

Non-US citizens must possess either a J-1 or F-1 Visa. Establishing a Guest Scientist agreement usually requires at least 4-6 weeks before arrival. For further guidance, contact a member of the CMAQ research team.

Staff positions, when available, will be advertised through USAJOBS. Exit
