Our Institute of Atmospheric Physics in Oberpfaffenhofen near Munich offers a


DLR-DAAD Doctoral Fellowship

Nr. 549: Lidar for Wind and Aerosol: Setup, Operation and Analysis of a Dual-Color Direct-Detection Doppler system


What to expect:

The Institute of Atmospheric Physics investigates the physics and chemistry of the global atmosphere from the Earth's surface up to the upper boundary of the middle atmosphere at about 120 km height. The department “Lidar” develops ground-based, airborne and spaceborne lidar systems. It applies them for active remote sensing of key meteorological parameters and atmospheric trace gases enabling research in weather and climate as well as increasing air traffic safety.


The department has developed and validated a prototype of a Doppler Wind lidar based on a novel direct-detection design, namely the use of fringe-imaging from a field-widened Michelson interferometer (project AEROLI). By design, the operation of this interferometric spectrometer (currently in UV, 3rd harmonic of laser wavelength) may be extended to the green (2nd harmonic). This shall allow the acquisition of further atmospheric data besides the wind, i.a. the aerosol-to-molecular backscatter ratio.


This capability is of high relevance for future validation of spaceborne wind and aerosol lidars as well as future evolutions of these.The proposed PostDoc project is centred around the optical setup and test of this extension to the existing lidar, its operation in a ground-based system and the analysis of the retrieved data. A rough timetable is foreseen as this:


  • Year 1: Introduction to this lidar’s theory and base lidar measurement equipment. Design of green channels extension.Integration, test and operation in ground-based lidar. Iterative setup improvements. Measurements including reference validation instrumentation.
  • Year 3: Data evaluation regarding atmospheric properties and systematic error analysis. Publication of results.


If you are passionate about advancing electrochemical systems and meet the qualifications, we would be delighted to receive your application.
