Short summary
The poorly characterised optical properties of atmospheric aerosols are one of the major uncertainties when modelling future climate change. Photoacoustic spectroscopy is an accurate and sensitive method for measurement of aerosol light absorption. Photoacoustic spectrometers require calibration; hence this study validates the use of ozone as a calibrant and simultaneously verifies the accuracy of the photoacoustic spectrometers in question.
