Contexto: "Since light absorption heating method (LAHM) quantifies the contribution of dust, black carbon (BC) to light absorption, with no distinction among them, the comparison between LAHM and SP2 helped to highlight that refractory black carbon dominates light absorption in the southern part of the Cordillera Blanca (nearby Huaraz), while dust accounts for the largest share of light absorbing particles (LAPs) in the northern area (Schmitt et al., 2015), confirming the higher contribution of anthropogenic LAPs in the proximity of urban agglomerates."

Termo equivalente: carbono negro refratário
Definição: "Black carbon is a carbonaceous aerosol formed during incomplete combustion of biomass and fossil fuels, characterized by strong absorption of visible light and resistance to chemical transformation. Refractory black carbon is the fraction of the absorbing carbonaceous material that has a boiling point close to 4000 K and emits visible light when heated to that temperature."

Definição em português: "O carbono negro é um aerossol majoritariamente composto por carbono elementar proveniente da combustão incompleta de combustíveis fósseis e de biomassa. Este tipo de carbono tem um importante papel no aquecimento global devido à sua alta capacidade de absorção da radiação solar. O carbono negro refratário é a porção desse material que apresenta grande estabilidade térmica, com uma temperatura de volatilização perto de 4.000 K."
