The University of North Carolina at Chapel Hill’s Institute for the Environment is hosting its 17th annual Community Modeling and Analysis System (CMAS) Conference Oct. 22-24 at the university’s Friday Center.

The annual conference has become an international hub and the premier resource for air quality modeling scientists to convene and share research and ideas on the state of the science.  The conference also explores policies relevant to air quality analyses and their impact on communities.

Each year the conference attracts more than 300 attendees including national and international air quality modelers, policy makers, academics, federal and state governmental and non-governmental agencies, and various industries, from more than a dozen countries.

This year’s keynote address will be delivered by Jesse Bash, a scientist at the U.S. Environmental Protection Agency’s (EPA) National Exposure Research Laboratory. Bash will discuss his work with atmospheric deposition of nitrogen in the Chesapeake watershed and tidal bay.

Carey Jang, also a scientist at the EPA, is the plenary session speaker. He will introduce  ABaCAS , a decision support tool for researchers and policy makers to conduct integrated assessments on air quality.

Adel Hanna, director of IE’s Center for Environmental Modeling for Policy Development Research and director of the CMAS Center will deliver the State of CMAS address.

The CMAS Center in the Institute for the Environment was established in cooperation with the U.S. Environmental Protection Agency to leverage the air quality community’s knowledge on air quality modeling and analyses in order to support community decision-makers in addressing air quality issues for the last 16 years.

In addition to this conference, the CMAS Center offers online training and support, air quality modeling software, data sharing, workshops, journal publications, and a visiting scientist programs. The Center’s training programs serve as an education and training core for those who need to learn about air quality, meteorological, and emissions models, and their uses. CMAS training programs reached more than 2,000 scientists in the past 16 years including training sessions in eight countries around the globe.
