Enhancement of snow albedo reduction and radiative forcing due to coated black carbon in snow
When black carbon (BC) is mixed internally with other atmospheric particles, the BC light absorption effect is enhanced. This study explicitly resolved the optical properties of coated BC in snow based on the core <math xmlns="http://www.w3.org/1998/Math/MathML" id="M1" displa...
