PhD Position on Secondary Ice Production with focus on Ice Fragmentation during Graupel Formation (m, f, d, n. a.)

The Leibniz Institute for Tropospheric Research (TROPOS) is an internationally renowned institute in the field of aerosol and cloud research. The Atmospheric Microphysics Department (AMP) researches atmospheric aerosol particles, their interactions with clouds and turbulence, and cloud microphysics. The focus is on both process-based studies and long-term observations, with which we contribute to the understanding of climate change and its consequences.

Highly oxidised products from isoprene - an underestimated source of aerosols in the atmosphere?

Experimental studies under atmospheric conditions show two important reaction pathways in the hydroxyl radical-initiated degradation of isoprene, which form highly oxidised peroxy radicals with 8 or 9 oxygen atoms and may be of global importance for the production of organic aerosols.
