Particulate matter < 2.5 μm (PM2.5), Particulate matter < 10 μm (PM10), and Ozone (O3) in the research places were measured between 2015 and 2017. Daily average temperature, humidity, wind speed, sunshine time, and yearly mean rainfall were represented between 2016–2017. Meteorological data were obtained in the open data portal of Korea Meteorological Administration; https://data.kma.go.kr/resources/html/en/aowdp.html (accessed on: 25 June 2021).
