[CRYOLIST] PhD position at University of Bremen, Germany open

The Institute of Environmental Physics (IUP) at the University of Bremen invites in the context of the new DFG-funded Transregional Collaborative Research Center 172 (SFB/Transregio) Arctic Amplification: Climate Relevant Atmospheric and Surface Processes, and Feedback Mechanisms (AC)3) applications for a
3-year Ph.D. position in

Remote Sensing of Sea Ice:
Retrieval of spectral surface reflection properties from satellite and airborne observations

In order to quantitatively better understand the increased global warming in the Arctic, it is important to assess optical surface properties of the ice covered Arctic Ocean on the global scale from satellite data. Such satellite based retrievals need to be validated against field and airborne observations, taking into account the differences in method, sensors, and observing and atmospheric conditions. The main focus of the research will be to analyze the sources of uncertainties (e.g. different spectral or angular resolution, varying cloud cover, varying surface properties) and use existing radiative transfer models (SCIATRAN, MCARATS) to evaluate the uncertainty when comparing data from satellite sensor and field or airborne campaigns. Such analyses and evaluations have to be done for various measurement methods, surface and atmospheric conditions. For the most common and important sources of uncertainty, an empirical correction can be developed using radiative transfer (RT) models. The task assumes not only running, but also improving the RT models (both models are written in Fortran), and bulk processing of satellite data (suggested to use Python).

Requirements

  • M.Sc. degree or equivalent in physics, oceanography, meteorology, remotesensing, geophysics, or related fields.

  • Skills in scientific computer programming (e.g., Python, IDL, Matlab or similar) and a strong interest to work in the field of satellite remote sensing

  • Expertise in sea ice research will be viewed favorable. We seek a candidate who is a team worker yet can conduct independent research.

General

Screening of applications will start within two week after publication, and the position will remain open until filled. The application should include details of relevant qualifications and experience, CV, copies of transcripts, and names of max two references. For more details see
