Abstract
This study analyzed the ozone concentration distribution across cities and counties in Gyeonggi-do (Province) from 2012 to 2021 to propose an ozone alert zone framework tailored to regional characteristics. Ozone concentration values were calculated using data from 69 urban air monitoring stations in Gyeonggi-do, and hierarchical clustering analysis was applied to divide the area into four clusters. Most clusters in Gyeonggi-do were delineated by high mountain ranges, indicating that geographical characteristics play a significant role in shaping ozone concentration patterns. These findings underscore the limitations of the current PM10-based ozone alert system and emphasize the need for zoning based on regional ozone concentration patterns.
