Note	The aethalometer is used to measure light absorbing aerosols in near real time. The instrument reports equivalent black carbon concentration as a function of wavelength, but also reports changes in optical transmission caused by particle deposition on the filter. The change in transmission is related to the light absorption coefficient via Beers law (see discussion here).
