This article describes the development of a sensitive method of measuring aerosol absorption at 532 nm with excellent time response (detection limit: 0.08 Mm(-1), 60 second average) using photoacoustic absorption spectroscopy. An accurate calibration method (accuracy of 1-2%) at atmospherically relevant absorption levels and independent validation of the photoacoustic technique is presented. An upper limit to the instrument precision for aerosol absorption measurement is approximate to 6% (2 sigma, 30 sec) while instrument accuracy is calculated to be approximate to 5%. A standard for aerosol absorption measurement techniques using well characterized absorbing aerosol is also proposed.
