Markus Hartmann

Markus Hartmann is a Researcher in the Department of Atmospheric Microphysics at the Leibniz Institute for Tropospheric Research (TROPOS) in Leipzig, Germany. His work focuses on characterizing bioaerosols and ice-nucleating particles (INPs) using real-time data from the SwisensPoleno Jupiter instrument at TROPOS's Melpitz research station, with particular emphasis on Arctic atmospheric processes.

Education:

• PhD in Atmospheric Science, Universität Leipzig (2021)

Research Focus: Dr. Hartmann investigates ice nucleation mechanisms and biogenic aerosol sources in polar regions. His work combines field measurements, laboratory analysis, and climate modeling to understand how biological particles influence cloud formation and Arctic amplification. Key areas include marine-derived INPs, aerosol-cloud interactions, and impacts of anthropogenic activities like shipping on atmospheric processes.

Publication Trends: Recent work (2020-2025) reveals a strong focus on Arctic ice-nucleating particles with increasing emphasis on marine biogenic sources and anthropogenic influences. His research shows growing integration of instrument development (e.g., PINCii chamber), multi-platform campaigns (aircraft, ship, ground), and policy-relevant studies on marine fuel regulations.

Projects & Field Work: Actively contributes to international initiatives including OLALA (lidar applications), BRACE-MY (cloud microphysics), BACSAM II (Arctic aircraft studies), and VOLCAN (alternative aviation fuels). Past involvement in (AC)³, PASCAL, ACE-SPACE, and SALTRACE demonstrates extensive polar field experience across Arctic and Antarctic regions.

Science Communication: Engages public through Kinderuni programs with talks like "On thin ice - chaos in the Arctic climate kitchen" (2024) and "Cow farts - why are they bad for climate?" (2019), translating complex climate science for young audiences.
