Abstract
The aerosol optical properties and chemical components of PM2.1 (particulate matter with a diameter of 2.1 µm or less) were investigated at Mount Gongga on the eastern slope of the Tibetan Plateau ...
Highlights
Atmospheric aerosols are a complex and dynamic mixture of solid and liquid particles from natural and anthropogenic sources, with diameters of approximately 10–3–10 μm (Chen et al 2014)
To investigate the sources of aerosol present over the eastern slope of the Tibetan Plateau, the optical and chemical properties of aerosols were measured during April 2012 and December 2014
When we divided the observational period into dry and wet seasons, we found numerous biomass burning spots existed in Southeast Asia in the dry season, and the southerly airflow transported smoke aerosols and anthropogenic fine particles to the Mount Gongga study site
Summary
Atmospheric aerosols are a complex and dynamic mixture of solid and liquid particles from natural and anthropogenic sources, with diameters of approximately 10–3–10 μm (Chen et al 2014). They play an important role in Earth’s radiation budget by scattering and absorbing solar radiation (Ackerman and Toon 1981; Xin et al 2017). Whether there is a pollutant transport channel affecting the environment of the Tibetan Plateau is an important question and, it would be desirable to investigate this topic using satellitebased measurements, this is difficult to achieve because of the problems caused by the surface albedo in plateau areas.
