In this project, we provide technology development and support for the routine forecast of air quality and ultraviolet intensity over the Taiwan area. The main tasks are: (1) Provide hardware and software maintenance of EPA’s “Air Quality Forecast Auxiliary System” and update relevant database in order to facilitate the operation of daily forecast of air quality; (2) Perform daily simulation of atmospheric dust deflation and transport from East Asia to the Taiwan area, predict the arrival time, duration, concentration and extent of dust incursion so as to provide a 48-hr advance notice; (3) Develop a dynamic air quality model to provide simulations of local and foreign air pollutants including those from biomass burning, provide 24 to 48 hr forecasts to assist routine operation of air quality forecasts; (4) Analyze observational data of air pollution episodes as well as boundary layer temperature profiler data, understand the relationship between atmospheric stability so as to help the improvement of air quality forecasts; (5) Analyze observational data and output from dynamic air quality model to help understanding the cause of air pollution episodes; (6) Utilize the temperature profiler data and the air pollution model output to improve the statistical forecasting of daily air pollution; (7) Provide hardware and software maintenance of EPA’s “MODIS” data system and the production of daily image product, as well as utilize the staellite data in improving air pollution forecast and for result vefirications.
