on the research topic

The retrieval of cloud, aerosol and surface parameters from HSI/EnMAP instrument

The time limitation is subject to the scientific qualification according to the Act of Academic Fixed-Term Contract, §2 (1) (WissZeitVG – Wissenschaftszeitvertrags-gesetz). Therefore, candidates may only be considered if they dispose of the respective scope of qualification periods according to §2 (1) WissZeitVG.


Job description

The post is embedded into the new project ‘XBAER4EnMAP: XBAER derived aerosol - cloud - surface - climate parameters from HSI/EnMAP’, funded by the German Aerospace Center starting from October 1st, 2022. The overall project aims to derive surface and atmospheric (cloud and aerosol) parameters for the recent launched instrument – HSI (Hyper Spectral Imager) onboard the German hyperspectral satellite mission EnMAP (Environmental Mapping and Analysis Program) (

One of the key scientific objectives of the task is to apply and further develop the sophisticated retrieval algorithm - eXtensible Bremen Aerosol/cloud and surfacE parameters Retrieval (XBAER). The XBAER algorithm is a retrieval algorithm developed at the Institute of Environmental Physics, University of Bremen, to derive surface and atmospheric parameters from satellite observations. The XBAER algorithm is currently being applied to various instruments (e.g. MERIS/OLCI onboard EnviSAT, AATSR/SLSTR onboard Sentinel-3) and provide global aerosol, cloud and surface data products. The other key scientific objective of the task is to explore the created HSI/ EnMAP surface & atmospheric dataset to improve our understanding on complex environmental/ecosystem-related processes.

The activities are carried out within the aerosol group at the Institute of Environmental Physics, University of Bremen. The institute provides a very good working atmosphere and facilities in an international working environment. Further general information can be found here: Information about the specific workgroup can be found here:


  • A scientific degree (diploma or master of science) in computer science, geographic information science, remote sensing, geophysics, environmental physics or closely related fields. The overall average grade should be better than 2.0 (according to German grading system) or be better than B (Anglo-Saxon grading system).
  • Very good computer skills to deal with big data and very good programming skills in at least one high level programming language.
  • Already existing basic knowledge in dealing with satellite data is a plus.
  • A creative and independent research and excellent communication and presentation skills in written and spoken English.

General hints

The university is family-friendly, diverse and sees itself as an international university. We therefore welcome all applicants regardless of gender, nationality, ethnic and social origin, religion/belief, disability, age, sexual orientation and identity.

As the University of Bremen intends to increase the proportion of female employees in science, women are particularly encouraged to apply.

In case of equal personal aptitudes and qualification priority will be given to disabled persons.

Please send your application documents including a cover letter stating the research interest, a master degree certificate, a curriculum vitae with research and technical background as they relate to the position, transcripts and contact information of, at least, two referees until December 9th, 2022 by indicating the job id A311/22 to:
