3 Open positions (PhD.PostDoc, Scientific Researcher)
at Theoretical Cloud Physics Group, Institute for Atmospheric Physics,
Johannes Gutenberg-University Mainz, Germany

(1) PhD position
Project: Spatially inhomogeneous cirrus: Influence on atmospheric radiation

Project summary: 
The radiative impact of cirrus clouds is quite uncertain. One possible reason 
for this problem is the occurrence of inhomogeneities inside cirrus clouds. The 
sources for these inhomogeneities are still unclear and should be investigated 
during this project. For this purpose, the large eddy model EULAG containing a 
bulk ice microphysics scheme and a radiation scheme will be used for idealised 
and realistic 2D/3D simulations of cirrus clouds under certain dynamical 
conditions. The project will be carried out together with two experimental 
groups (MPI Mainz, University of Leipzig); the measurement data as obtained 
from an aircraft campaign will be used for comparison with the model 
simulations and conversely the model simulations will be used for interpreting 
the experimental data. The aircraft campaign will be supported by the 
theory/model part via flight planning and weather forecasts.

The project duration is 3 years with a salary of 75% E13 TVL.

The project is funded by the German Research Foundation (DFG); it is a joint 
research project with experimental groups "Particle Chemistry" (Prof. Borrmann, 
MPI Mainz, Germany) and "Atmospheric Radiation" (Prof. Wendisch, University of 
Leipzig, Germany).

The required qualifications are:
- Master’s degree / Diploma in Meteorology, Physics, Mathematics or a closely 
related discipline
- Experience in a higher programming language
- Interest in cloud physics/atmospheric sciences

Applications with CV and names of 2-3 references should be sent via email to 
Prof. Peter Spichtinger (spichtin@uni-mainz.de). Applications will be screened 
immediately until the position is filled.


(2) PostDoc position
Project: Impact of cirrus clouds on large scale dynamics

Project summary: 
Cirrus clouds are crucially forced by dynamics on different scales, especially 
by large-scale features. On the other, cirrus clouds could influence the 
tropopause region and introduce perturbations, which in turn feedback to 
large-scale dynamics.This potential effect will be evaluated in details during 
this project. For this purpose meteorological analyses will be evaluated and 
idealized life cycle experiments of Rossby waves will be carried out in order 
to obtain a clearer picture about the feedbacks between ice clouds in the 
tropopause region and large-scale dynamics. The model simulations will be 
carried out with the research model EULAG.

This project has a preliminary duration of 1 year with the possibility of 
extension for 2-3 years, subject to funding by the German Research Foundation. 
The salary for this position will be 100% E13 TVL.

The required qualifications are:
- PhD in Meteorology/Atmospheric Sciences, Physics, Applied Mathematics or a 
closely related discipline
- Experience in a higher programming language (preferably FORTRAN)
- Experience in data investigation for huge data sets and/or in numerical 
modelling on high-performance computers
- Interest in interaction of large-scale dynamics and cloud processes

Applications with CV and names of 2-3 references should be sent via email to 
Prof. Peter Spichtinger (spichtin@uni-mainz.de). Applications will be screened 
immediately until the position is filled.


(3) Scientific researcher position

In the recently established research group "Theoretical Clouds Physics" a 
position of a research scientist is available. The main focus of the research 
is on the multiscale nature of (ice) clouds, i.e. on interactions of cloud 
processes and dynamics on different scales, ranging from the micro-scale (i.e. 
microphysical processes) over turbulence and (gravity) waves up to large-scale 
dynamics. Especially the scale interactions of various processes in ice clouds 
and the formation of macroscopic structures is not well known but is crucial 
for future reliable estimates of the radiative net impact of ice clouds.

The research methods for investigation the multiscale nature of ice clouds 
could include theoretical investigations, data investigation and modelling 
approaches. As a group modelling tool the research model EULAG should be 
established and maintained by the successful applicant.

The required qualifications are:
- PhD in Meteorology/Atmospheric Sciences, Physics, Applied Mathematics or a 
closely related discipline
- Experience in a higher programming language (preferably FORTRAN)
- Experience in numerical modelling of atmospheric processes (preferably on 
high-performance computers)
- Interest in interaction of dynamics and cloud processes on different scales

The successful candidate will also be expected to supervise students 
(Bachelor/Master/PhD) and to contribute to the teaching programme for the 
Bachelor’s and Master’s programme in meteorology of the Institute for 
Atmospheric Physics at University of Mainz. Possibilities for further 
scientific and academic qualification (e.g. german "Habilitation" if requested) 
can be offered. The salary for this position will be 100% E13 TVL. The position 
is initially offered for 3 year with a possible extension of 3 years.

Applications with CV and names of 2-3 references should be sent via email to 
Prof. Peter Spichtinger (spichtin@uni-mainz.de). Applications will be screened 
immediately until the position is filled.
