In this respect, precipitation is an important component and plays a key role in the removal of air pollutants. When precipitation occurs, raindrops fall, inducing below cloud scavenging, absorbing pollutants and removing them from the atmosphere. The wet scavenging process is affected by the strength, duration, concentration, and distribution of air pollutants. The aerosol wet scavenging coefficient ( Λ m ) by precipitation is used to formulate a change in aerosol concentration ( C ) during the precipitation time ( t ). According to the equation, the wet scavenging coefficient was calculated using multi-year PM 2.5 hourly concentration data from the NAMIS (National Ambient air quality Monitoring Information System). The main purpose of this study is to gain a better understanding of scavenging coefficients including characteristics unique to Korea by using measurement data for five years for 12 cities. By applying a developed scavenging coefficient to the three-dimensional air quality model, these results provide wider support for improving the accuracy of simulating particle matters in East Asia. An implication of the new scavenging coefficient is a value that better reflects precipitation characteristics in Korea and one that can also help research scavenging characteristics in East Asia in the future and contribute to improving modeling accuracy.","PeriodicalId":16269,"journal":{"name":"Journal of Korean Society for Atmospheric Environment","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45120914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the observation areas, we categorized them into six zones: Gamman Port (A) with ships and cargo handling equipment, residential area (B) adjacent to the port, factory area (C) where steel mills are located, redevelopment area of Bukhang Port (D), industrial area (E) with shipbuilding yards, and industrial complex (F) with ship berthing facilities. We examined the characteristics of fine particle concentration based on the concentration changes of PM 2.5 in each zone. The average concentration for the entire observation period, including all zones, was 17.0 ± 10.0 μg/m 3 . For each zone, A to F, the concentrations were 19.0 ± 12.8, 21.0 ± 14.5, 18.6 ± 12.5, 15.0 ± 7.8, 14.2 ± 7.3, and 15.9 ± 8.8 μg/m 3 , respectively. Zones A, B, and C showed higher concentrations compared to zones D, E, and F. When the wind speed was strong, the concentration difference between zones A, B, and C and zones D, E, and F was small. However, as the wind speed decreased, the concentration difference between zones became more significant. The average PM 2.5 concentration, including all zones, varied with wind direction: 14.1 ± 11.6, 17.5 ± 9.3, 19.1 ± 8.7, and 17.7 ± 6.5 μg/m 3 for east, west, south, and north winds, respectively, showing the highest concentration during south winds and the lowest during east winds. Through scanning LIDAR observations, we were able to confirm the concentration changes in each zone according to the concentration difference and variations in wind direction and speed. The results of this study indicate that scanning LIDAR can provide important information for accurately understanding the fine particle status and formulating policies for mitigation and countermeasures.","PeriodicalId":16269,"journal":{"name":"Journal of Korean Society for Atmospheric Environment","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43529269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
