Both nitrogen dioxide (NO2) and organic nitrates (ONs) are very important trace gases in the atmosphere. The concentration of NO2 is one of the most important indicators to assess the degree of air pollution. In addition, NO2 is t

Strong solar irradiance in Tibetan Plateau provides heat source for the plateau's atmosphere, driving atmospheric circulation of East Asian and the "butterfly effect" of global climate change. Synchronous observation of the ground

Aiming at the problem that the deviation in the fitting of aerosol spectrum distribution function can seriously affect the calculation and prediction of visibility, a segmental fitting method combining Junge spectrum and Deirmendj

Aiming at the highly sensitive and stable detection of trace amounts of Cd2+ in water, an experimental study based on Al sheet electrodeposition enrichment (ED) combined with laser-induced breakdown spectroscopy (LIBS) to detect C

Heavy metals in atmospheric particulate matter not noly pollute the ecology but also affect human health. Therefore, their chemical form and bioavailability are of great significance for the evaluation of health and ecological ris

In recent years, air pollution has become one of the important factors limiting the improvement of urban living environment quality in Xi'an City, China. The local government has taken a series of measures to control air pollution

A synergistic pollution process of PM2.5 and ozone (O3) occurred in Beijing-Tianjin-Hebei Region, China, from April 16 to 22, 2018. In order to gain a deeper understanding of the occurrence and the causes of the synergetic polluti

In July 2022, mobile monitoring was conducted on the personal exposure concentration of PM2.5, O3 and NO2 air pollutants under two commuting modes of bus and walking in Urumqi, and the saptiotemporal changes and influencing factor

Based on the sea surface backscattering model, a space-borne lidar data screening method using CALIOP dual-wavelength sea surface signal for data quality control is proposed. The global sea surface wind speed is retrieved from CAL

Underwater image enhancement technology has the potential to improve the quality and visibility of underwater images, which has important application value in enriching digital media resources, underwater exploration, underwater c
