On 6 May 2003, NOAA and the U.S. EPA signed a Memorandum of Understanding and a Memorandum of Agreement to expand their collaboration toward the development of a national air-quality forecasting (AQF) system. NOAA and the U.S. EPA are jointly developing various components of the AQF system, which will be run operationally at the NOAA's National Weather Service. Currently, the AQF system is based on the National Centers for Environmental Prediction's (NCEP's) Eta Model and the U.S. EPA's Community Multiscale Air Quality (CMAQ) Modeling System. The Eta/CMAQ AQF system is designed to provide twice daily numerical guidance for air-quality forecasts for the U.S. Initially, the capability includes surface-level O3 forecasts of hourly average concentrations as well as 8-h averages. Future expansion of the system will include PM2.5. The current forecast domain is the Northeast U.S. using a 12-km horizontal grid spacing on a Lambert Conformal map projection.
