At the Leibniz Institute of Atmospheric Physics (IAP), a full-time position (100%) in the Department “Radar Remote Sensing” is available as

PhD Student, atmosphere and ionosphere investigations over the Baltic Sea area (f/m/d)

The position is initially offered for three years with a start date in April 2025. The salary is according to class EG 13 TV-L. The fixed-term contract is based on § 2 WissZeitVG.

Take part in cutting-edge research with real-world impact!

This position is part of the collaborative project “Atmospheric Impact on the R-Mode Positioning System,” involving the IAP, the University of Greifswald, the DLR Institute for Solar-Terrestrial Physics, the DLR Institute of Communications and Navigation, and the Leibniz Institute for Baltic Sea Research Warnemünde.

Satellite-based navigation systems (GNSS) are critical for accurate positioning and time synchronization; however, natural and human-made interferences can disrupt GNSS signals, particularly in the Baltic Sea region. Such disruptions pose significant risks for air and maritime traffic. This project seeks to develop a reliable backup system utilizing medium wave R-Mode (Ranging Mode) technology, capable of delivering accurate position and time data when GNSS signals fail.

R-Mode transmitters emit waves that travel along Earth’s surface and reflect off the E region of the ionosphere (90–130 km altitude). The interaction of these waves—affected by both reflection and absorption in the D region—presents analytical challenges. To address these, the project focuses on improving the understanding of ionization processes and dynamic conditions within this atmospheric region through detailed observations and analysis.

Your Tasks:

• Develop/adapt techniques for ionization measurements (Faraday rotation, absorption) in the D region using an existing 3~MHz radar.
• Analysis of the dynamical situation of the relevant altitude region employing various radar wind data over the Baltic Sea region.
• Association of derived parameters to other data sources (Lidar, model) and large scale atmospheric processes.

This role is ideal for a candidate passionate about radar and radio technology, atmospheric dynamics, and exploring the intersection of data science and atmospheric physics.

Your Qualifications / Experience:

• A Master’s degree (or equivalent) in physics, engineering, or a related field.
• A strong interest in atmospheric dynamics, radar techniques, radio propagation, and data processing.
• Solid communication skills and an ability to work independently and responsibly.
• Proficiency in English for collaboration and documentation.

What we offer:

• A vibrant research environment near the beautiful Baltic Sea (German Riviera).
• Access to modern research facilities and tools, alongside collaborative opportunities in international settings.
• Flexible working hours and options for remote work (where applicable).
• Competitive benefits including participation in the German public sector pension scheme (VBL).
• Support for work-life balance, including family-friendly policies and services.
• An opportunity to be part of a renowned institute within the Leibniz Association, known for its commitment to equality, flexibility, and professional growth.
