Evaluation of the National Air Quality Forecast System (NAQFS) Developmental Large Domain Model: Summary of the Air Quality Forecasters Focus Group Workshop

William F. Ryan, Penn State University, University Park, PA; and P. Davidson and P. Stokols

The National Air Quality Forecast System (NAQFS), developed as a partnership between the Environmental Protection Agency (EPA) and the National Oceanic and Atmospheric Administration (NOAA), has provided operational numerical forecast model guidance for ozone forecasters beginning in the summer of 2003. During the summer of 2004, an experimental version of the NAQFS was exercised on a larger domain and evaluated by a focus group made up of state and local air quality forecasters. This focus group was formed in 2003 to evaluate the initial NAQFS model during that summer's ozone season. The focus group was expanded, along with the experimental model, in 2004 and provided evaluation and feedback on model performance during the summer of 2004. At the conclusion of the 2004 ozone forecast season, a workshop was held at NOAA Headquarters at which forecasters and model developers met to present results, discuss model performance and make recommendations for future activities. A summary of the activities of the focus group and a report on the workshop is presented here.
