Vertical Structure and Seasonal Evolution of Atmospheric Oxidizing Capacity across Urban and Rural Regions: Observational Constraints from OH Radical Production Pathways

Tiliang Zou, Chengzhi Xing, Zhijian Tang, Yikai Li et autres

Abstract. Atmospheric oxidizing capacity (AOC) drives the formation of secondary pollutants, yet conventional surface observations fail to resolve its pronounced vertical heterogeneity, often leading to incomplete interpretations of regional pollution chemistry. Using ground-based hyperspectral vertical remote sensing observations collected between March and …

Measurement report: Validation of multi-satellite remote sensing products and potential source apportionment of BrO and IO in the Arctic using ship-based DOAS

Qijin Zhang, Chengzhi Xing, Yikai Li, Haochen Peng et autres

Arctic reactive halogen species are pivotal in mediating polar air-sea interactions and global biogeochemical cycling. Based on ship-based Multi-Axis Differential Optical Absorption Spectroscopy (MAX-DOAS) observations from the 12th Chinese National Arctic Research Expedition (July to September 2021), this study provides a systematic …

UAV Hyperspectral Stereoscopic Remote Sensing Technique Supports NO 2 Localization With a Meter-Level Spatial Resolution

Haochen Peng, Chengzhi Xing, Tianyu Tang, Wei Tan et autres

Undetected meter-level pollution sources significantly increase health risks and remain difficult to identify and regulate. Satellite observations are constrained by coarse spatial resolution and cloud cover, while ground-based measurements rely on a single mode, offering only partial views of pollutant distribution. Both …

Vertical Differences in NO 2 -to-HONO Heterogeneous Conversion and HONO-Driven OH Production over Inland, Coastal, and Island Regions

Yikai Li, Chengzhi Xing, Haochen Peng, Peiyuan Jiao et autres

Photolysis of nitrous acid (HONO) is a key source of hydroxyl radicals (OH), but the vertical distribution of its generation mechanism and photolysis effects across different land–sea locations remains unclear. This study used ground-based hyperspectral technology to conduct long-term vertical observations in …

Fast-hyperspectral imaging remote sensing: Emission quantification of NO2 and SO2 from marine vessels

Chengzhi Xing, Shaocong Wei, Yikai Li, Peiyuan Jiao et autres

Abstract Marine vessels play a vital role in the global economy; however, their negative impact on the marine atmospheric environment is a growing concern. Quantifying marine vessel emissions is an essential prerequisite for controlling these emissions and improving the marine atmospheric environment. …
