The main focus of this project, is to collect Radiosonde data for 7 days per season in the Yunlin Offshore Industrial Estate Park during Summer and Winter.
Then processing it with data capture, to set up the Yunlin Offshore Industrial Estate
Park (Yun Jia Nan Air Quality District) Air quality model simulation data plan.
Moreover, this project also will be used in the Environmental law enforcement profession review conference and the Environmental law enforcement skill seminar.
To improve the supervision and inspection of air pollutant, in order to enhance the efficiency and effectiveness of inspectors in air quality protection and ability in total air pollutant inspection.
According to the already completed Radiosonde observations on this project, together with reanalysis of other high altitude meteorological data of the Banqiao of Central Weather Bureau , Magong and Pingtung of Air Force Weather Wing radiosonde station and the NCEP. It shows that during the summer observation period, there was little differences between the Vertical Temperature profiles of different sounding stations. However during the winter observation period compared to summer there was a significant amount of difference between the various sounding stations. In the Winter period regardless of day or night, the air temperature in Banqiao station was the lowest in all heights, whereas the other stations had high and lows. The averages of the height in the inversion layer Banqiao was the highest, Magong station being second with Pingtung station being the lowest. In this project (Taixi Station) the inversion layer height was between Magong and Pingtung.
The results of the Radiosonde observation were used to carry out air quality simulations with a desired mixing layer height estimate. The estimate showed that during the day, whether in summer or winter, on average the radiosonde observation Banqiao had the highest mixed height layers, Magong second and Pingtung the lowest. In this project (Taixi Station) the mixed layer height was between Magong and Pingtung. During the night, in summer Banqiao was the highest with Magong being the highest in winter. Overall during the summer period
each station results had little differences, however in the winter the differences quite noticeable (especially in the day).
Combining the above analyses, If Yunlin region using the data from Banqiao station, then the estimated mixed layer height will likely be overestimated. If using the data from Pingtung station, then the estimated mixed layer height will likely be underestimated. Magong station data results of the mixed layer height, seems to have a higher correlation to the current project (Taixi station). Therefore basing on our previous analyses, if using Magong station long term radiosonde data for this project (Taixi station), adjusting with the radiosonde observation data then proceed with mixing layer height estimates, should be able to gain a closer result to the Yunlin mixed layer height estimates.
This project used the different chimney height of emission sources from an Offshore Industrial Estate Park, to carry out a simulation test. Using the radiosonde observations according adjusted meteorological data and Central Weather Bureau Wuqi data coupled with the Banqiao sound station meteorological data to carry out an air quality model simulation. Comparing the two simulation tests, it can be seen that there is indeed a difference between the two simulations, with no consistent trends existing between the two.
