[ES_JOBS_NET] Postdoc on tropical cirrus modeling at KIT, Germany

[Voigt, Aiko (IMK)]

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 
(aiko.voigt at kit.edu). 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. More information about the 
NSF-PIRE collaboration can be found at
