Short summary

A new approach to retrieve stratospheric aerosol size distributions is developed to characterize smoke aerosol properties. Pyrocumulonimbus can strongly perturb stratospheric aerosol concentrations. Simulations are conducted to describe stratospheric aerosol properties for bimodal lognormal distributions. Observations from SAGEIII/ISS are used to determined stratospheric smoke aerosol size distributions and optical and microphysical properties and are validated against in situ measurements.
