Brown carbon can warm atmosphere study at IIT-K
A team of researchers from the indian institue of technology (IIT) kanpur in their study highlighted that carbonaceous aerosols such as black carbon (BC) and certain organic carbon species called brown carbon have the potential to warm the atmosphere by absorbing light. the study on brown carbon, whose rolewas lesser-known, is based on their experiment in kanpur, u.p.
in order to better characterise brown carbon, the team presented experimental and modelled absorption properties of submicron aerosoles measured in kanpur.
