COVER STORY Atmospheric aerosols are tiny solid or liquid-covered particles suspended in the air. Aerosols (particulate matter) play a very crucial role in the dynamics of the atmosphere. Almost every weather event in the troposphere is mediated by aerosols, either directly or indirectly. Aerosols serve as nuclei for cloud condensation and precipitation, and also control the tropospheric temperature by absorbing or scattering solar radiation. However, these life-supporting aerosols can become harmful when their natural equilibrium in the environment is disturbed. One such problematic aerosol is Black Carbon (BC). BC refers to carbonaceous, polycyclic organic aerosols found in the atmosphere and…
