Open Positions

The Leipzig Institute for Meteorology (LIM), Germany, invites applications for a

PhD Position

 Variability of Arctic cloud top cooling as a function of cloud microphysical properties derived from airborne thermal infrared imagery

We offer a PhD position to study Arctic clouds using state of the art airborne remote sensing instruments. The aim of this project is to use downward viewing airborne thermal infrared imagery to investigate the cloud top temperature with high spatial (< 10 m pixel size) and temporal (100 Hz) resolution. The measurements will be used to quantify the influence of spatial cloud inhomogeneities on the cloud top cooling, a key process leading to the long life time of Arctic clouds and potentially contributing to the amplified Arctic warming (Arctic Amplification). Details of the project motivation are given below.

The position is funded within the Transregional Collaborative Research Center TR172 on “ArctiC Amplification: Climate Relevant Atmospheric and SurfaCe Processes, and Feedback Mechanisms (AC)³” ( by the University Leipzig. Within the TR172, LIM together with the collaboration partners (Universities of Cologne and Bremen, TROPOS and Alfred Wegener Institute) aim to better observe, understand, and simulate processes leading to the current drastic climate changes in the Arctic. The PhD candidate will work in close collaboration with these (AC)³ partners and link own results to their modelling and satellite remote sensing activities.

Terms of employment

The PhD position (65% TV-L E13) is awarded for 3 years and open starting as soon as possible. We offer a productive and interdisciplinary working group including comprehensive supervision and integration into the Leipzig Graduate School on Clouds, Aerosol and Radiation ( which is part of the ITRG of (AC)³ (

  • Evaluation, analysis and interpretation of the measurement data within the framework of the doctoral thesis
  • Close interdisciplinary cooperation with the other international project partners
  • Co-organisation and participation in laboratory and field measurement campaigns
  • The PhD candidate will participate a ship campaign over several weeks in the Southern Ocean / Antarctica in the beginning of 2023


Applicants should have a Master’s degree in chemistry, biochemistry, environmental sciences, or related disciplines. Experiences in atmospheric sciences and analytical chemistry (e.g. HPLC-MS) is desired. Knowledge of atmospheric measurement techniques, experience of data analysis using statistical methods, and knowledge of  programming languages like R, Matlab or Python are of advantage. Fluent English in written and oral form is mandatory. A cumulative dissertation including three publications in scientific peer-reviewed journals will be expected.
