Primary brown carbon (BrC) co-emitted with black carbon (BC) from biomass burning is an important light-absorbing carbonaceous aerosol. Black carbon is a kind of an aerosol. Chemically, black carbon (BC) is a component of fine particulate matter (PM ≤ 2.5 µm in aerodynamic diameter).Black carbon consists of pure carbon in several linked forms. An aerosol is a suspension of fine solid particles or liquid droplets in the air. ... 2 Year Package is the most ideal and highly recommended as the UPSC Cycle (Start of … Black carbon is an important contributor to warming because it is very effective at absorbing light and heating its surroundings.
