Atmospheric brown clouds (ABCs)

“Atmospheric brown clouds (ABCs), observed as widespread layers of brownish haze, are regional scale plumes of air pollutants, consisting of mainly aerosol particles (such as black carbon (BC) and non BC), and precursor gases (e.g. CH4, CO,NMVOCs, NOx), which produce aerosols and ozone in the atmosphere. ABCs and their interaction with build-up of greenhouse gases (GHGs) significantly affect the regional climate, hydrological cycle, glacial melting, agriculture production, and human health.

The United Nations Environment Programme (UNEP) commissioned the Atmospheric …
