Type of employment


In the framework of different atmospheric missions (cf. GOME-2, and the EU Copernicus Missions Sentinel-5 Precursor (S5P), Sentinel-4, Sentinel-5) DLR’s Remote Sensing Technology Institute develops algorithms for the accurate derivation of ozone and other trace gases (e.g. NO2, SO2, HCHO, CHOCHO) as well as aerosol and cloud properties from satellite data obtained with GOME- and OMI-type atmospheric spectrometers. These algorithms are used operationally in near-real-time processing systems of ESA, EUMETSAT and the DLR AC-SAF. At the end of 2017, the TROPOMI instrument was launched on board the EU/ESA Copernicus satellite S5P, followed in 2018 by the third GOME-2 sensor on EUMETSAT's MetOp-C platform.

The Remote Sensing Technology Institute has many years of experience in deriving atmospheric products from satellite measurements ranging from GOME/ERS-2, SCIAMACHY/ENVISAT, GOME-2/METOP to TROPOMI/S5P and continuing in the future with the Copernicus Sentinel missions Sentinel-4 and Sentinel-5 (see e.g. https://atmos.eoc.dlr.de/tropomi/  and https://atmos.eoc.dlr.de/gome2/ ).

The work is performed in close cooperation with national and international partners. We offer an excellent working environment and the opportunity to collaborate with the leading scientists in the field of satellite-based remote sensing of the atmosphere.

The holder of the position will be responsible for the following tasks:

  • development of novel and refinement of existing scientific algorithms for the retrieval of aerosol properties in the UV/VIS/NIR spectral range or ozone profiles in the UV/VIS spectral range using GOME- and TROPOMI-type instruments, here especially for the EU Copernicus Sentinel-5 atmospheric sensor
  • integration of the algorithms in pre-operational software and operational processors  
  • verification, validation and documentation of the results
  • publication of results in peer-reviewed journals
  • presentation of results in project meetings and at international conferences

Your qualifications:

  • completed scientific university studies (university diploma/master's degree) in physics or a related field
  • PhD in physics or a related field
  • several years of experience in the field of atmospheric remote sensing, esp. using data from the sensor types GOME-2, OMI and TROPOMI
  • very good knowledge in the retrieval of atmospheric properties using UV/VIS/NIR spectrometers in at least one of the following areas: i) retrieval of aerosol properties (optical depth, aerosol UV index) in the UV/VIS/NIR spectral range, or, ii) retrieval of ozone profiles in the UV/VIS spectral range, as demonstrated by scientific publications
  • solid knowledge in methods of numerical mathematics
  • very good programming experience with C/C++, Fortran or Python under Linux/Unix
  • good command of English
  • team spirit

Your benefits:

Look forward to a fulfilling job with an employer who appreciates your commitment and supports your personal and professional development. Our unique infrastructure offers you a working environment in which you have unparalleled scope to develop your creative ideas and accomplish your professional objectives. Our human resources policy places great value on a healthy family and work-life-balance as well as equal opportunities for persons of all genders (f/m/x). Individuals with disabilities will be given preferential consideration in the event their qualifications are equivalent to those of other candidates.
