[Met-jobs] Vacancy: 1 Research Associate, 1 Postdoc, 2 PhD Positions at the University of Bonn (Germany)

From Silke Troemel <>
Date Wed, 15 Aug 2018 12:31:04 +0200

Pending approval of external funding, the Meteorological Institute of  the University of Bonn invites applications for 4 positions starting
January 2019 within the proposed DFG research unit 2589 „Near-Realtime Quantitative Precipitation Estimation and Prediction“ (RealPEP). See
also <>

RealPEP thrives to achieve significant improvements at all stages along  the process chain from Quantitative Precipitation Estimation (QPE),
Precipitation Nowcasting (QPN), numerical  prediction of quantitative precipitation (QPF) and predicting discharge  and potential flash floods in small- to meso-scale catchments (FFP). RealPEP will rely on a multi-sensor data exploitation platform to  monitor the precipitation generating atmosphere and tackle urgent
science questions to better identify mechanisms that determine the  onset, location, intensity, and development of precipitating systems.
Developments will be implemented for near-realtime processing in order  to be able to mitigate risks to society and ecosystems.

The positions include:

1) A position as Research Associate or Software engineer to build and  maintain the data collection and exploitation platform, which combines
all cloud and precipitation-related observations and algorithms developed in the research unit. The starting point is a C++ processing
framework developed at the German national weather service (Deutscher Wetterdienst, DWD). The successful candidate will enable the framework
to digest different data sources and extend it with tools developed in the research unit related especially to QPE and QPN.

2) A PostDoc position to develop and improve near-real time QPE primarily based on observations from the German national weather service
(DWD) network of polarimetric C-band radars. One core objective is to adapt and optimize precipitation retrievals by exploiting specific attenuation information from the
C-band radars. She/he will closely collaborate with a colleague at the Karlsruhe Institute of Technology (KIT) Campus Alpine
(Garmisch-Partenkirchen), who exploits attenuation measurements of commercial microwave links (CMLs), which provide the backhaul of countrywide cell phone networks.

3) A PhD student or PostDoc position to improve and extend advection-based nowcasting by including lifecycle effects in radar algorithms. Two strategies are foreseen: In a first step, trends in rainfall intensity, size and shape of the precipitating cells observed during previous time steps will be extrapolated in time. In a second
step polarimetric radar signatures indicative for potential changes in precipitation generation (e.g. columns of enhanced differential reflectivity, so-called ZDR-columns) will be exploited for refinements of the approach.

4) A PhD student to work closely together with a PostDoc at the German national weather service (Deutscher Wetterdienst, DWD) on the
assimilation of information from polarimetric radar observations in the framework of the KENDA data assimilation platform. Polarimetric information can be in the form of
polarimetric observations, derived hydrometeor densities and types, and nowcasted fields. The PhD candidate will concentrate on the assimilation of mixing rates contained in an observation composite and on the direct assimilation of polarimetric observations.

Interested candidates should send a CV, a cover letter describing motivation, background, training, and research interests, certificates,
and the contact information of two persons, which can be asked for references, as a single PDF of less than 5MB to
<> for positions 1, 2, or 3 and and to
<> for position 4.
