Air quality models are playing vital roles in tasks concerning the air quality planning and regulatory compliance checking. As the content of air quality models becomes more sophisticated, both in their scientific mechanisms and in their data input, a successful job requires different aspect in supports and specialties. Taiwan EPA urged by this requirement has established the Air Quality Modeling Center (AQMC), which recruits expertise and data resources in different institutes over the Island and is connected over the Internet platform to carry out its missions. In this project, it is intended to layout the organization and operation of AQMC, Taiwan. As an answer to please from the air pollution community, AQMC’s operation is aimed to serve the community needs in three major areas, namely the expertise in advanced air pollution modeling, the data acquisition needs in model input and the computational platform needs. Furthermore, to meet the continuous challenge of both the scientific and legal advancement in the community, AQMC also serves as the forum for new ideas and cooperative endeavors for future Air Quality. According to the sixth and eighth terms in the air pollution control act, the sources applied to emit or change pollutant, which the quantity is larger than a certain value, have to demonstrate that their impact on air quality is below the tolerance values by air quality model. Therefore, air quality model become a necessary tool to determine the permit of stationary source. Besides, air quality model traditionally can be used on air quality management plan, air quality impact assessment, and state implement plan, and et al. The project of air quality modeling center is designed to support various air quality models in needs of regulation, administration, and development. The results are shown briefly as follows.
