Polarimetric measurements quantifying the angular distribution of light scattering by aerosol particles, i.e. the phase function, provide ample information on aerosol microphysical properties. The broader aim of this project is to bridge the gap between ground-based and remote sensing aerosol observations, which rely on polarimetry, by deploying a new laser imaging polar nephelometer for in-situ measurements of phase functions. Acquired data will also be used to assess aerosol property retrieval algorithms.
During this PhD you will:
- Perform laboratory and field experiments to determine phase functions and aerosol physical properties of well constrained and more complex atmospheric aerosols
- Adapt existing inversion codes to retrieve aerosol microphysical properties
- Compare retrieval results against independent measurements to identify capabilities and limitations of different data inversion approaches
- Collaborate with internal and external project team members for closure studies based on parallel in situ and remote sensing observations
- Write and contribute to high quality peer-reviewed publications on aerosol polarimetry
- The PhD degree will be received from ETH Zurich
- Master's degree in physics, environmental sciences/engineering, or closely related field
- First experience in applied laboratory and / or field work
- Interest in atmospheric processes combined with initiative and enthusiasm to conduct research in a multidisciplinary team
- Excellent command of written and spoken English
- Background in script based programming and data analysis techniques is advantageous
