The main purpose of this project is to collect radiosonde data in the Yunlin Offshore Industrial Estate Park seven days a season and to process the data to construct the data of the Yunlin Offshore Industrial Estate Park (Yun Jia Nan Air Quality District) Air quality model simulation. In addition, this project will also assist in holding the Environmental Law Enforcement Profession Review Conference and the Environmental Law Enforcement Skill Seminar, which are to enhance the efficiency and ability of air quality protection inspectors. According to the finished radiosonde observations of this project, and the comparisons and analyses with upper air meteorological observations in Banqiao radiosonde station of the Central Weather Bureau, Magong and Pingtung of the Air Force Weather Wing and the NCEP analysis data. The temperature profiles of all radiosonde stations are relatively similar during the summer observation period. However, the temperature profiles of all radiosonde stations are obviously different during the winter observation period. Generally speaking, the temperature profiles of NCEP analysis data and Magong radiosonde observation are most close to which of the radiosonde observation of this project (Taixi station). The mixed layer height, which is the input data of air quality model, of each radiosonde station is also estimated and compared with which of Taixi station. The result shows that the mixed layer height of NCEP analysis data and Magong radiosonde observation are quite similar to which of Taixi station. In this project, the air quality simulation tests of all emission sources in Offshore Industrial Estate Park are finished. The input meteorological data are which is adjusted by this project and which is released by the Air Quality Model Supporting Center. After the simulations, the difference of these two simulations is about -6%~25%, which is not negligible. However, using the data which is released by the Air Quality Model Supporting Center will generally overestimate the concentration of air pollutant except PM10.
