This project combines the UV-Index forecasting system and the monitoring program of the dust storm. In all, following results are obtained: Maintain the equipment of the UV-Index forecasting system. Assess and improve the predicting system of UV-Index. Prove the observation, so as to ensure the quality of the UV-Index monitoring. Analysis the results of UV-Index monitoring and predicting, in order to find out UV variation tendency. Maintain a third-level working standard; Close contact with EPA to execute the calibration task; Maintain a reliable calibration system and QA/QC operational procedure; Calibrate of all on-site UVI instruments. Compare the calibration result, and set up a QA/QC operational procedure on site; Upgrade the continents of dust storm monitoring over the years. Upgrade the website of the dust storm database. Case study on the dust storms and the emergency admissions in Taipei, Taiwan from 1995-2002
