Detailed explanation-1: -What has been the effect of the heavily polluted “brown clouds” what are now common in some parts of India? Rainfall has decreased and temperatures are cooler.
Detailed explanation-2: -Atmospheric brown clouds (ABCs) are basically layers of air pollution consisting of aerosols such as black carbon (BC), organic carbon, and dust that absorb and scatter solar radiation (1). ABCs also contain other anthropogenic aerosols such as sulfates, nitrates, and fly ash, which primarily scatter solar radiation.
Detailed explanation-3: -Brown clouds contain a variety of toxic aerosols, carcinogens and particles, including fine particulate matter (PM2.5). These have been linked with a variety of health effects, including respiratory disease and cardiovascular problems.
