Goethe University you will work with Dr. Anna Possner and
Prof. Joachim Curtius at the Institute for Atmospheric and
Environmental Sciences on Campus Riedberg in
Frankfurt/Main. We will use passive tracer simulations
with the ICON model at various resolutions to: (i)
contextualise aircraft measurements obtained over the
Amazon basin, and (ii) to understand the downward
transport of newly formed particles in the tropics. This
will include the development and evaluation of ICON
configurations over the Amazon basin and the tropics.
During this time, you will also be closely collaborating
with the people planning, undertaking and analysing field
measurements over the tropics during CAFE-BRAZIL. Further
simulations with ICON-MESSy and comparisons to MECON
simulations in collaboration with project partners are
also planned.</span></font></font></font><br>

you should hold (or be close to defend) a PhD in
atmospheric modelling or atmospheric chemistry.
Preference will be given to candidates with experience
in model development, atmospheric chemistry, or the
dynamics of the tropics. Model development, such as
the implementation of passive tracers, is an integral
part of this position. Proficient skill in programming
languages such as Fortran and Python are thus an
absolute necessity. In addition, previous experience
in working with regional weather/climate models such
as WRF, ICON or COSMO is preferable. Publication of
the results in peer-reviewed scientific journals and
presentations at international conferences are
expected. Further funds for professional development
are also available.</span></span></font></font></font></strong><br>
