Jan-Lukas Tirpitz recently received his Ph.D. at the IUP Heidelberg. During his work, he pushed the limits of the MAX-DOAS remote sensing technique, which analyses spectra of scattered skylight in multiple viewing directions to infer vertical distributions of atmospheric aerosols and trace gases as well as aerosol properties. By making use of the information contained in the polarisation state of skylight and by implementing novel inversion approaches, Jan-Lukas enhanced the sensitivity of MAX-DOAS observations particularly to aerosol abundances and aerosol properties.

In the IUP colloquium, he will outline the remarkable properties of skylight polarisation and demonstrate its usefulness for atmospheric remote sensing on the basis of his results.
