Maximilian Maahn joined the Leipzig Institute for Meteorology in July 2020 and leads the drOPS (clouD and pRecipitation Observations for Process Studies) group. His main research interests include enhancing radar observations of polar clouds and precipitation and understanding how clouds are influenced by aerosols through remote sensing and in-situ observations. He is currently developing a novel in situ sensor for snowfall, the Video In Situ Snowfall Sensor (VISSS). Read a feature about his background and work at the website of the ARM program at https://www.arm.gov/news/features/post/54283 | Maximilian Maahn joined the Leipzig Institute for Meteorology in July 2020 and leads the drOPS (clouD and pRecipitation Observations for Process Studies) group.
