Terms of employment
The PhD positions (A) – (G) (75% TV-L E13) are awarded for 3 years with possible extension to up to four years. We offer a productive and interdisciplinary working group including comprehensive supervision and integration into the thriving Leipzig Graduate School on Clouds, Aerosol and Radiation (http://www.lgs-car.tropos.de/).
The position (I) (50% TV-L E13) is awarded for up to 4 years. We offer a productive and interdisciplinary working atmosphere including several possibilities for career development.

Qualification requirements
For the PhD positions (A) – (G) we expect strong interest in atmospheric science, in particular in cloud physics, remote sensing, radiative transfer, and climate dynamics. Applicants should have a Master in Meteorology or a related field. Experience in high-level scientific programming for data analysis is desirable. Experience in cloud, aerosol, and/or radiation physics and atmospheric modeling would be advantageous for positions (C) – (G) , and scientific programming (Fortran, python) as well as experience with Unix/Linux is required for these positions. Candidates must possess excellent communication skills in written and spoken English.

Candidates should have very good English skills, both written and spoken.
Applications
Interested candidates should send a cover letter describing background and motivation; a CV, training and research interests; certificates; and the contact information of two referees as a single PDF to m.brueckner[at]uni-leipzig.de.
Please clearly indicate which position(s) you apply for. Review of applications will begin 15 January 2024 and continue until the positions have been filled.
Selection

PhD Position (m, f, d) on the Satellite-based Characterization of Cloud Evolution in Arctic Cold Air Outbreaks
The Leibniz Institute for Tropospheric Research (TROPOS) is an internationally renowned research institute in the field of aerosol and cloud research, and a member of the Leibniz Association. Its remote sensing department is offering a 4-year PhD position within the transregional collaborative research center TR172: Arctic Amplification, Climate relevant Atmospheric and SurfaCe Processes and Feedback Mechanisms (AC)³. The planned work shall be carried out in close collaboration with national project partners and in particular the
Universities of Leipzig and Cologne.

The PhD student (m, f, d) will carry out the following tasks:

• Characterization of cloud properties, structure and evolution including their radiative effects during Arctic Cold Air Outbreaks (CAO) with satellite observations and other complementary data sources
• Comparison of operational satellite products with observations data collected from aircraft during field campaign for CAO
• Long-term analysis of satellite products and reanalysis datasets to investigate natural variability and potential trends in the occurrence frequency and strength of CAO as reflected in the associated cloud properties and radiative effects

We are looking for an excellent scientist with a University degree in Meteorology or a related subject such as Physics, Mathematics or Geosciences. Prior experience in analyzing large-volume observational data and with programming in Python or similar computer languages are highly desirable. Fluency in English and the ability to clearly present research results both in spoken and written form are also essential.
