An accurate assessment of black carbon (BC) climate and health impacts requires knowledge of its mass absorption cross-section (MACBC) – a parameter linking optical and mass measurements. The mean MACBC for freshly emitted soot typically spans a narrow range of 8 ± 1 m2 g⁻1 at 550 nm1,2 but is modif ...

We compared aerosol light absorption measurements by a photothermal interferometer (PTI) and by extinction minus scattering (EMS) in a laboratory setting using test aerosols with single scattering albedo (SSA) in the range from about 0.1 to 1. The EMS method reported higher light absorption coeffici ...
