Dear all,

the DLR Institute of Remote Sensing (Oberpfaffenhofen & Berlin, Germany) is looking for a PhD candidate to work on the SO2 cloud height retrieval based on Sentinel-5p data.


Research Topic:

Determination of volcanic SO2 cloud layer heights based on satellite UV measurements


DLR Institute:

Remote Sensing Technology Institute (IMF) at DLR Berlin-Adlershof and Oberpfaffenhofen



Doctoral Fellow (DAAD Fellowship)


Job Specification:           

The institute's Atmospheric Processors section conducts research on atmospheric remote sensing with infrared and ultraviolet spectrometers. Research on the mathematical and physical basics of atmospheric remote sensing is focused on radiative transfer modelling, mathematics of inversion, and electromagnetic scattering.


Volcanic eruptions can have a major impact on local population, aviation as well as on a global scale. DOAS techniques allow the determination of the amount of volcanic SO2 in the atmosphere; however the retrieval of the plume height requires computationally expensive direct fitting techniques.

The new generation of hyper-spectral atmospheric composition sensors (e.g. Sentinel-5 Precursor) has unprecedented high spatial resolution paired with enhanced radiometric sensitivity resulting in large data volumes that are needed to be processed in a real time mode. This necessitates  new approaches based on high-performance computing, hyper-spectral content analysis and machine learning.


This PhD-project will be focused on the development and validation of an algorithm to retrieve SO2 layer heights from Sentinel-5 Precursor measurements. In order to validate and intercompare with the results from other satellite sensors and ground stations, a dispersion model has to be applied to investigate the movement of the volcanic plume.


We are striving to increase the proportion of female employees and therefore particularly welcome applications from women. Disabled applicants with equivalent qualifications will be given preferential treatment.


Earliest Start Date:         

September 2019
