In order to analyze the meteorological factors that cause changes in air quality and how to impact different region of Taiwan, we classify the weather patterns and expand the database of 2019-2020 continuously. We also optimize several function, and set up the process about importing the types of flow fields in the vicinity of Taiwan into inquiry system, We have built a database to quickly search the historical data to provide reference for forecasters. The second part is continuing the past internal research of EPA.We collect and organize the typhoon location of air pollution events in 2009-2018. We analyze the concentration of PM 2.5, PM10, O3, O3_8hr in every grid and monitoring station, then product the distribution graph. According to the research results, we develop the climate model of air quality during typhoon in recent ten years. Furthermore, we evaluate the feasibility, process, benefit about how importing the climate model into inquiry system. In this project, we also analysis the causes of air pollution episodes include comparing the winter season from 2018-2019 and O3 air pollution events in September 2020. We also provided the advice report of the boundary layer and sensor application of unmanned flying vehicles. On the other hand, we have provided three graphic to transfer the correct message about the causes of air pollution to the public. We made implemented training programs to the staff of the EPA. We have submitted monthly report before the 10th of each month.
