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. 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. Read more
Atmospheric Brown Cloud (ABC) Programme is an effort to mitigate near-term climate change and improve air quality for the better living of human being.
