Information for New Users

Welcome to CMAS! We are a community of environmental and air quality modelers. If you are interested in downloading CMAQ, SMOKE, BenMAP, or any of our other supported models, if you are looking for assistance with any of our supported models, if you are looking for a bibliography of air quality modeling related published works, or you are looking for an atmospheric modeling position, you've come to the right place!

The first thing you should do is create a CMAS user account. This will allow you full access to everything the site has to offer, including model downloads. Once you have a CMAS account, registering for our annual CMAS Conference or model trainings is a snap. Even if you change your email or address, you can easily edit your contact information by clicking on the appropriate link on the right side of the page (once you are logged in).

If you are looking for help with any of our supported models, you should visit our Help Desk, which describes all of the helpful information available on our site and suggests the following ordered approach to finding a solution: 1) Search through model documentation, 2) Read through the FAQs, 3) Search the M3User archives, and 4) add yourself to the m3user listserve, where someone in the modeling community is always willing to point you in the right direction.

You can always use our search bar at the top to search within our site. You can always reach a CMAS team member with general CMAS-related questions by emailing cmas@unc.edu. And don't forget to read the latest issue of our quarterly publication, the CMAS Quarterly!
