Master student (f/m/d) for Implementation of a cross-polarised detection channel into heterodyne Doppler lidar for improved cloud studies

The Leibniz Institute for Tropospheric Research (TROPOS) in Leipzig investigates physical
and chemical processes in the polluted troposphere. Its research focuses on aerosol and
clouds, which strongly influence energy, water, trace substances, climate, and human health.
TROPOS combines field studies, laboratory experiments, and numerical models to better
understand these processes and predict the effects on humans.

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.
