Current Research Fields

Experimental investigations on the microphysical and light scattering properties of ice crystals to assess the climate impact of contrails, cirrus and mixed-phase clouds:
- in-situ studies with research aircrafts and at high altitude environmental research stations
- simulation experiments at the cloud chamber AIDA
Light scattering and absorption properties of aerosols in the UV-VIS-NIR spectral range in the context of the direct shortwave radiative effect of aerosols:
- laboratory experiments with aerosol samples from different sources
- field measurements at different locations
Real-time monitoring of biological aerosols by single particle dual-waveband fluorescence analysis:
- ambient aerosol measurements at different locations
Development of novel optical instrumentation:
- airborne instruments for in-situ cloud research
- photoacoustic aerosol absorption spectrometers
- laboratory and field instruments using particle light interaction methods
