摘要	The purpose of this project is to maintain forecasting systems to facilitate daily forecast of air quality over the Taiwan area. The main works include: Maintain and operate the numerical forecasting model, the China dust dynamic numerical model (TAQM/KOSA；WRFDUST), local dust dynamic model (TAQM/TWKOSA), Taiwan Air Quality Model (TAQM), Community Multi-scale Air Quality (CMAQ) Model and mesoscale numerical weather prediction system (MM5 and WRF) included. Analyze the characteristic of atmospheric factors, ozone and PM2.5 between the model simulated results, site monitoring data and MODIS satellite retrieval data.
