Auxiliary Air Quality Forecast system and Mineral dust forecast system of 2012
| 英文摘要 | The purpose of this project is to maintain forecasting systems to facilitate daily forecast of air quality over the Taiwan area. The main accomplishments include: (1) Maintain and operate the Mineral Dust Model (China dust and Taiwan local dust) to provide the forecasting message, as well as Air Quality Dynamic Numerical Models (CMAQ、TAQM). (2) To assist to setup the new workstation purchased by EPA to increase the forecast ability.\.(3) Porting the dynamic models to the new sever of CWB (4)Analysis the data of forecasts and monitoring for local mineral dust in 2011. (5)To collect the information of dust size distribution of the source in China and Mongolia and to establish the technique to process the NDVI data by satellite monitoring for China Dust Dynamic Forecasting Model. (6) Develop dynamic numerical models (WRF) coupled with mineral land surface model to increase the ability to estimate the soil moisture. (7) Analyses the ozone condensation by TAQM and CMAQ. (8) Analyses selected episodes for the purpose of improving air quality and China Mineral dust forecasts. (9) Assessment for the forecasting ability of China Mineral Dust Dynamic model. (10) Provide special-duty manpower to EPA for daily forecasts of air pollution. (11) Project coordinate director join the China dust event forecasting examining meeting and provide the expert opinion to EPA. (12) Analyze the relationship between AOD、ground truth of meteorological factor and aerosol vertical distribution, so as to facilitate to transfer AOD to the near surface PM2.5 concentration. (13) To check and adjustment for the statistical method used in auxiliary air quality forecast system. (14) Rebuilt the function of the auxiliary air quality forecast system to suit the ask of EPA to change the forecast times from one to two per day. (15) Held two times of educational and technique training on 22th Oct. in EPA . On-going work for sustainable development of the forecasting systems will focus on: to maintain forecasting systems to facilitate daily forecast of air quality over the Taiwan area. Developing different numerical forecast model systems to offer diverse information for a better objective forecast and to provide special-duty manpower to EPA for daily forecasts of air pollution. | ||
