The Institute for Energy and Climate Research, Stratosphere (IEK-7), studies chemical, microphysical and dynamical processes in the upper troposphere and stratosphere and the role they play in the climate system. We are seeking a new Ph.D. student in the ''Theory'' group to develop a Lagrangian transport module for the new German atmospheric model ICON. The Ph.D. project is part of the large project of the German Helmholtz Association “Advanced Earth System Modelling (ESM) capacity”. The focus of ESM is to develop and apply a world-leading Earth system modeling infrastructure. The Ph.D. work will be performed within a three-year program of the Graduate School HITEC.
We are looking to recruit a
PhD student “Developing and applying a Lagrangian transport module for the new German atmospheric model ICON”
The group at IEK-7 has a long-standing tradition in developing and applying Lagrangian transport modules, in particularly the Chemical Lagrangian Model of the Stratosphere (CLaMS). These transport modules have recently been integrated in the Chemistry climate model EMAC using the Messy coupler. Using Lagrangian transport has distinct advantages for simulations in atmospheric regions where strong tracer gradient occur, e.g. in the atmospheric jet regions and in the vicinity of the tropopause. The improved transport of trace gases (e.g, water vapor) is expected to have an important impact on model results including results on climate change.
The Ph.D. candidate will deal with the coupling of the ICON model (available from external groups) with the Lagrangian transport, which is developed, maintained and employed
at IEK-7. In a first step, the coupled version of the ICON model with Lagrangian transport will have to be developed. The first tests will demonstrate the differences and advantages of the Lagrangian transport compared to the classic Eulerian transport in ICON. Finally, scientific studies of transport in the upper troposphere, lower stratosphere, based on the newly developed model, will be conducted.
