2018 Joint International Conference on ABaCAS and CMAS-Asia-Pacific

2018 Joint International Conference on ABaCAS and CMAS-Asia-Pacific

We are pleased to announce that the Community Modeling and Analysis System (CMAS) conference is coming to the Asia-Pacific in 2018. The 1st CMAS-Asia-Pacific conference will be held on May 21-23, 2018 in Beijing, China, jointly with the 6th Air Benefit and Cost and Attainment Assessment (ABaCAS) Conference. The joint conference is hosted by Tsinghua University, and organized jointly by South China University of Technology, Zhejiang University, University of North Carolina, and University of Tennessee with the support from China Ministry of Environment, U.S. Environmental Protection Agency, and U.S. Energy Foundation. The joint conference aims at providing a high-level platform for air quality scientists, model developers and policy makers from various disciplines to exchange ideas and views on key issues related to atmospheric model development and applications to address environment and climate issues from local to global scales, especially in some Asia-Pacific countries where the air pollution is still a severe problem.

In addition to the two-day conference (May 22-23), a one-day training workshop (May 21) on the "Community Multiscale Air Quality Modeling System (CMAQ)" and "Air Benefit and Cost and Attainment Assessment System (ABaCAS)" will also be provided to air quality modelers, managers and scientists of interest with demo and hands-on sessions on cutting-edge air quality decision support and modeling assessment tools.


One of the major tasks of the CMAS Center outreach effort is to organize annual conferences. The purpose of these conferences is to allow the model user and development communities to share their experiences with air quality models, modeling, and model development. The first annual Models-3 conference was sponsored by the USEPA and was held in Arlington, VA on June 12-14, 2000. With Models-3 and CMAQ still in development at that time, the goal of the conference was to take a look at the needs of the modeling community and to consider the advantages of using a common modeling system. Two years and three CMAQ releases later, after the modeling community had spent some time using CMAQ and integrating it with other components of Models-3, like SMOKE, a second conference was in order. The inaugural Models-3 conference under the auspices of the CMAS took place in October, 2002 at the EPA research campus located in RTP, North Carolina. With over 150 attendees, the focus of the conference was on Models-3 performance and applications. It was met with great enthusiasm by the community and was a huge success, with many attendees calling for subsequent conferences to be longer to accommodate more presentations and discussions.

The CMAS plans to offer annual conferences to help connect the members of the atmospheric modeling and model research communities. Building off of the experiences from previous conferences and assimilating feedback from past attendees, the CMAS will focus each conference on the pertinent issues of the day.
