Postdoctoral position in high-resolution modeling of tropical cirrus clouds

Karlsruhe Institute of Technology (KIT), Institute of Meteorology and Climate Research – Department Troposphere Research, Karlsruhe, Germany

The research group of Dr. Aiko Voigt wishes to recruit a postdoctoral scientist to work on tropical cirrus clouds and their modeling in ICON. The position is part of the DFG-funded project „TropiC - Understanding tropical cirrus by combining laboratory cloud simulation and field experiments with process and circulation modelling“, and contributes to the international NSF-PIRE collaboration on cirrus clouds led by the University of Chicago.

Tropical cirrus and their radiative interactions play a key role in the climate system and for the atmospheric circulation, including the monsoons and the tropical rain belts. To better understand cirrus, the DFG project combines experiments at the AIDA cloud chamber, process-based box modeling, and high-resolution large-scale modeling with ICON. The project partners include Dr. Ottmar Möhler (KIT) and Martina Krämer (Forschungszentrum Jülich). The project is linked to the international NSF-PIRE collaboration, which includes partners from the US (University of Chicago, University of Washington, Harvard, Princeton), France (Laboratoire de Meteorologie Dynamique) and Switzerland (ETH Zürich).

The advertised position aims to clarify how horizontal resolution, vertical resolution and cloud microphysics affect the ability of the climate and weather model ICON to simulate cirrus, and how this affects the circulation and climate change. To this end, a hierarchy of ICON simulations will be performed ranging from global low-resolution setups (80 km horizontal resolution) to limited-area high-resolution setups (2 km), and with different vertical resolution and cloud microphysical schemes. Furthermore, pseudo-global warming simulations in the limited-area model setup are planned to study the cirrus response to climate change. The model results will be compared to process-based box models from the Jülich partner, to observational data from the Stratoclim campaign, as well as to model results from the international NSF-PIRE partners.

We are seeking enthusiastic applicants with a doctoral degree in meteorology, atmospheric science or climate science and a proven track record in research. Experience in numerical modeling and large-scale atmospheric dynamics is required, experience with the ICON model is a plus. The position requires good communication skills and the abilitiy to work in a team as well as independently. The position offers the possibility to closely interact with German and international colleagues, and to participate in the annual NSF-PIRE meeting in the US.

The position is remunerated according to TV-L E13 with extensive social and health care benefits. The start date is flexible – with a preferred start date of January 1, 2020. Review of applications will begin on May 15, 2019 and will continue until the position is filled.

For questions about the position, please contact Dr. Aiko Voigt ( Applications shall be directed to Dr. Aiko Voigt via email in one pdf-file and shall include (1) a CV with a list of publications, (2) a letter of motivation (1 page maximum), and (3) contact details of at least two references.
