We are proud to announce the successful disputation of our SICSS member Ronny Badeke
His dissertation “Small-scale modeling of dispersion and chemistry of ship plumes in urban areas” was supervised by Prof. Dr. Kay-Christian Emeis (UHH; on the left) and Dr. Volker Matthias (Helmholtz-Zentrum hereon; on the right).
Ronny used numerical chemistry transport models to evaluate the effect of large ships on the air pollution close to ships and in harbor cities. He developed parameterization functions for the ship emission distribution, which account for local meteorology and technical data of the ship. This allows an improved representation of plume rise and turbulence effects. The developed “Flexplume” emission distribution improved nitrogen oxide model-measurement agreement inside of harbor areas and allow for a more accurate representation of air quality, exposure and health effects from the shipping sector.
Ronny is a member of the Helmholtz-Zentrum Hereon, Institute of Coastal Environmental Chemistry, and he had a guest contract at Universität Hamburg (working group Mesoscale and Microscale Modeling – MeMi).
Ronny’s future plans?
Ronny already started working on his PostDoc project “LUKAS” at Hereon in cooperation with the Bundeswehr University Munich, Helmholtz-Zentrum Munich and University of Rostock. He will continue working on ship plume modeling and is currently developing an algorithm for forecasting ship plume pollution events at the German coast of the Baltic Sea.
