I work in the field of atmospheric remote sensing of aerosols and clouds. I do experimental research in the form of field experiements and theoretical work in the form of method development. The main tools I use for this purpose are lidar and sun photometer instruments. The focus of my work is on the optical characterisation of aerosol particles, the investigation of the contribution of different particle types to an aerosol mixture and the retrieval of microphysical properties by means of the so-called inversion of the measured optical data.
The focus of my work is on mineral dust particles whose non-spherical shape has significant effects on their interaction with electromagnetic radiation and separated them from most other kinds of aerosol particles.
- ground-based and spaceborne remote sensing of clouds, aerosols, and aerosol-cloud interaction
- field measurements with active and passive remote-sensing instruments
- monitoring of boundary-layer development and cloud base with lidar
- characterizing aerosol optical properties, mixing states, and dispersion based on active and passive remote-sensing observations from ground and space
- method and software development for the analysis of multiwavelength depolarization Raman lidar data and subsequently deduced inversion products
- inversion of multiwavelength lidar data for retrieval of aerosol microphysical properties
- consolidation of aerosol microphysical properties from remote-sensing and in-situ observations
- air-quality monitoring from space
