Volatile organic compounds (VOCs) are important precursors of urban secondary organic aerosol (SOA) and ozone (O3) pollution. Industrial parks are important sources for anthropogenic VOCs, with main fugitive emission of characteri

A portable coherent lidar system has been developed, which has the advantages of compact structure, small volume, lightweight, and high degree of automation. The overall weight of the system is no more than 15 kg, and the lidar ca

Based on the ground data, wind lidar data, wind profile radar data, and Guangzhou S-band dual polarization radar data from the Guangzhou mega city comprehensive observation experiment in June and July 2019, the WindPrintS4000 wind

Uncooled infrared cameras are widely used in the field of gas leak detection due to the advantages of low cost, long life and stable performance. An excellent image denoising algorithm can effectively improve the sensitivity and a

To address the problem of continuous and accurate measurement of atmospheric NO2 at night, a nighttime atmospheric NO2 detection system based on target reflection light is developed. The system mainly consists of a transmitting un

Hydrogen cyanide (HCN) is an important product released during cigarette combustion, which seriously endangers human health. However, traditional methods such as gas chromatography are difficult to achieve real-time measurements d

High sensitivity of ammonia detection from different emission sources can provide certain reference for environmental management and medical diagnosis. However, current ammonia sensors have the disadvantages of weak absorption lin

The characteristics and meteorological causes of ozone (O3) pollution in Xuancheng City, China, were analyzed based on the ambient air quality monitoring data in 2020 and the meteorological observation data of the same period. The

In order to verify the application effect of surface reflectance data of hyperspectral automatic field observation equipment, the application and verification of in-orbit calibration data of Gaofen-2 (GF-2) satellite remote sensor
