Establish New Air Pollution Indicators Using Temperature Humidity and Wind Speed

Abstract

In Taiwan the emphasis on air quality and related issues has been increased year by year mainly because of the vigorous development of research in related fields and the rapid spread of knowledge The public has gradually realized that the air pollutants will affect the health of the human body and even harm the development of other organisms This topic has become more concerned In 2016 the Environmental Protection Administration of Executive Yuan changed PSI (Pollutant Standards Index) to be Air Quality Index (AQI) The value of AQI is to integrate the main six pollutants aerosols (PM10) sulphur dioxide (SO2) nitrogen dioxide (NO2) carbon monoxide (CO) ozone (O3) and fine aerosols (PM2 5) by selecting the most serious one This study refers to the multi-air quality index (RAQI) proposed by Lin et al (2003) Besides in order to improve the insufficiency of AQI which only used the most serious index value of six pollutants Li and Qiu (1996) constructed RAQI with the concept of entropy function The adjusted Taiwan air quality index is proposed and further to consider the influence of temperature humidity wind speed and geographic information of the AQI station This study used simulation data to explore the statistical nature of AQI and compare the adjusted air quality indicators and the performance of AQI and RAQI The real data analysis was carried out in Fengshan Qianzhen and Meinong stations in Kaohsiung City The results show that the adjusted air quality indicators proposed by this study can better distinguish the air quality It is recommended that relevant units can refer to and carry out subsequent extension and application
