Short summary
We address specialities of differential optical absorption spectroscopy of scattered light in the presence of strong absorbers (like ozone), where the optical depth becomes a non-linear function of the absorber concentration. We quantify the non-linearity using higher-order terms by expanding the radiative transfer equation in a Taylor series.
