Three-Dimensional Structural and Diurnal Dynamics of NO 2 and HCHO by UAV Hyperspectral in Bangkok

Tiliang Zou, Worapop Thongsame, Chonlada Bennett, Chengzhi Xing et autres

Fine-scale characterization of urban air pollution remains constrained by observational limitations. Here we used UAV-based hyperspectral remote sensing to conduct multitemporal and multialtitude measurements in Bangkok. High-temporal-resolution observations resolve pronounced diurnal signatures of traffic emissions: NO2 peaks in the morning under stable …

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 …

Abstract. Photolysis of HONO and O3 in the troposphere is a primary source of OH radical and a fundamental control on atmospheric oxidative capacity. Their vertical distributions and diurnal evolution are therefore essential for elucidating photochemical processes in the planetary boundary layer …

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 …
