Maximilian Maahn joined the Leipzig Institute for Meteorology in July 2020. His main research interests include enhancing radar observations of polar clouds and precipitation and understanding how clouds are influenced by aerosols through surface- and in-situ observations. Currently, he is investigating how local emissions from industrial facilities in Alaska modify the ratio between liquid droplets and ice particles in mixed-phase clouds.
