The Atmospheric Physics group at the Institute for Atmospheric and Climate Science (IAC) invites applications for a 3-year to 3.5-year PhD Position in Experimental Aerosol and Cloud Physics on targeted seeding with a drone. Our research focuses on the role of aerosol particles and clouds in the climate system. Our goal is to gain a better understanding of the cloud microphysical processes leading to precipitation in clouds involving ice.
The PhD project is part of the newly funded ERC project CloudLab that includes three PhDs and 2 PostDocs. Within CloudLab, ice nucleating particles from a drone will be injected into supercooled stratus clouds to investigate microphysical changes, including fundamental aspects of ice formation and growth. The project combines a multi-dimensional approach of targeted cloud seeding with a focus on wintertime stratus clouds in Switzerland. The microphysical changes induced by the seeding will be measured in-situ with a tethered balloon system and using ground-based remote sensing instrumentation. The analysis of the cloud seeding events will be used to validate and improve the cloud microphysics scheme in the Swiss weather forecast model and ultimately precipitation forecasts.
- Participate in multiple field campaigns in the winter months, where stratus clouds over the Swiss Plateau are partially glaciated by glaciogenic seeding.
- Develop a cloud seeding aperture on a drone and measure the dispersion of the seeding plume.
- Confirm that seeding is changing the cloud particle size distribution and analyze the effects of seeding with different concentrations.
- MSc (or equivalent) in atmospheric/environmental science, physics, engineering, or a related field.
- Sound knowledge of the English language, both orally and written, is expected.
- Field work experience with aerosol / ice nucleating particle measurements, drone measurement/development and/or cloud seeding is an advantage.
- Motivation to work in the field in rough conditions (at night).
- Good communication and time management skills, as well as a willingness to participate in a collaborative and supportive research environment.
- Applications from members of underrepresented groups in academia are specifically encouraged.
We are looking forward to receiving your online application with the following documents:
- Cover letter describing your motivation and research experience (max 1 page)
- Curriculum vitae
- Digital copies of BSc and MSc educational records
- Name and contact details of two references
Please note that we exclusively accept applications submitted through our online application portal. Applications via email or postal services will not be considered.
Applicants interested in PhD Position in Experimental Cloud Physics on ice crystal growth induced by seeding also, should mention their interest in the cover letter and only apply once.
