Impact/Purpose:
The objectives of this task are to continue development and improvement of EPA's mesoscale (regional through urban scale) air quality modeling systems, such as the Community Multiscale Air Quality (CMAQ) model, as air quality management and NAAQS implementation tools. This task focuses on needed research and development of air quality models targeted for a major CMAQ model release in FY08. Model development for a broad scope of application is envisioned. For example, CMAQ will need to be able to simulate air quality feedbacks to meteorology and climate as well as intercontinental transport. The 2008 release of CMAQ is timed to coincide with EPA/OAR's and the states' needs for an improved model for assessments of progress (mid-course corrections) in the post-SIP submittal timeframe.
Description:
Air quality modeling is continuously expanding in sophistication and function. Currently, air quality models are being used for research, forecasting, regulatory related emission control strategies, and other applications. Results from air-quality model applications are closely linked to meteorological model that drives the dispersion, deposition, chemical transport, and chemical processes. Thus, modeling systems should be evaluated by considering all components/models involved.
