Refection of Mitigation Strategy for Air Pollution based on Clean Air Policy Support System - Concentration Analysis from the Atmospheric Monitoring Network in the Seoul and Gwangju Areas

Abstract

As particulate matter is of great interest, many mitigation policies related to PM have been established based on Clean Air Policy Support System (CAPSS) as the official statistics for emission rates. CAPSS has been developed for several decades to understand the potential source and receptor regions. The assessment of the air quality impacted from sources, concentrations monitored at the National Monitoring Stations (NMS) is often utilized to understand the evaluation of reduction effects for source control strategies. Although CAPSS should be able to represent air pollution monitoring station data, the limitation can be exist. In this study, their concentration colinearities between CAPSS and NMS for Korean 16 administrartive regions were assessed. As a result, the high rank CAPSS in 2016 is barely uncorrelated with high concentrations at NMS from 2016 to 2019. In addition, the multi-statistical approaches through combinations of time series analysis and correlation matrix based on NMS have been performed for the Seoul and Gwangju areas. The future applications were proposed for their amendments such as a new management plan for the source control.
