Short summary
Photoacoustic spectroscopy is a commonly used technique for measuring light absorption by aerosols, but it requires careful calibration to be accurate. Here, we explore the use of one popular calibrant, ozone, and demonstrate that its response is dependent on the identity of the bath gas used.
