Black Carbon Sources: Biomass burning, Wildfires, Mobile sources (Fossil fuel), Industry, Waste incineration Measure methods: On line: Multi-Wavalength Aethalometer, Multi Angle Absorpion Photometer (MAAP) EC/OC semicontinuos and off line measurement on filter “…A joint EMEP/ACTRIS/COLOSSAL intensive measurement period was conducted in winter 2017-2018 (IMP Winter 2018), using multi-wavelength aethalometer measurements of equivalent black carbon (EBC) and a novel application of positive matrix factorisation (PMF) for source apportionment of Equivalent Black Carbon into fossil fuel (EBCff) and biomass burning (EBCbb) origin…” (EMEP Report 1/2018).

The Aethalometer® is an instrument that uses a real-time optical analysis to determine the mass concentration of Black Carbon particles collected from an air stream passing through a filter. Two configurations: 2-Wavelength (infra-red 880 nm for Black Carbon; ultraviolet 370 nm for aromatic organic compounds- brown carbon) and 7-Wavelength (7 sources from 370 nm to 950 nm). Multi-Angle Absorption Photometer (MAAP) measures the amount of light (wavelength 637 nm) that is transmitted through and scattered back from a particle laden glass fibre filter.
