Abstract. A high O3 episode with the large increases in surface ozone by 21–42 ppbv and nocturnal levels exceeding 70 was observed region between Xiamen Quanzhou over southeastern coast of China during 12–14 June 2014, before Typhoon Hagibis landing. Variations O3, NO2, CO meteorology event clearly suggest a substantial impact peripheral downdrafts large-scale typhoon circulation on such an excluding contributions photochemical production horizontal transport.

Abstract. Severe ozone (O3) pollution episodes plague a few regions in eastern China at certain times of the year, e.g., Yangtze River Delta (YRD). However, formation mechanisms, including meteorological factors, contributing to these severe events remain elusive. A summer smog stretched over YRD region from 22 25 August 2016. This event displayed hourly surface O3 concentrations that exceeded 300 µg m−3 on Nanjing, an urban area western YRD. The weather pattern during this period was...
Surface ozone (O3) is influenced not only by anthropogenic emissions but also meteorological factors, with wind direction being one of the most overlooked factors. Here, we combine observational data both O3 and flow to compare variation in surface between coastal inland regions Fujian, a province southeast coast China complicated topography. We further conduct numerical simulation using global chemical transport model, GEOS-Chem, interpret results, explore linkages these variations flows,...
In this study, the multi-year data of meteorology and O3 from remote sensing ground observations are applied to characterize 3-D changes in troposphere over central eastern China (CEC) induced by tropical cyclones (TCs) subtropical ocean regions Northwest Pacific. The CEC-regional average near-surface levels is significantly elevated with 6.0 ppb large coverage TCs ocean, while alter weakly, indicating latitudinal-located offshore could largely influence variations CEC. sub-seasonal change...

Abstract. The impact of stratospheric intrusions (SIs) on Central and Eastern China (CEC) with severe ozone pollution presents a range uncertainties, underscoring the imperative for sustained research endeavors. In this study, we propose traceability assessment method that can derive high-resolution critical source areas (CSAs) SIs by utilizing ambient air quality observations, global (re)analysis data, customized Lagrangian simulations. This approach enables us to facilitate meticulous...
Abstract This study investigated the regional transport of particulate matter (PM 2.5 ) leading to air pollution in Fuzhou, west bank Taiwan Strait (WBTS), which has a relatively good quality with lower aerosol optical depth than that East China. The continental polluted zone over coast China was identified as an belt, and daily dynamics observed by MODIS remote sensing indicated southward fine WBTS along coast. external pollutants from contributed 84% PM detected while only 16% due local...
The northward typhoon configuration along the southeast coast of China (TCN-SEC) is one key circulation patterns influencing coastal cities in (CCSE). Here, we analyzed air quality CCSE during high-incidence period from 2019 to 2021. Multi-source measurements were carried out explore impact super 2114 ‘Chanthu’ on CCSE. results showed that TCN-SEC and its surrounding weather situation had a favorable increase pollutant concentration CCSE, especially O3 concentration. From 13 September 17...
