Scientist (m/f/d) Working in Remote-sensing of Sea-ice Thickness

AWI - Alfred Wegener Institute for Polar and Marine Research

Bremerhaven, Germany

The Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) is a member of the Helmholtz Association (HGF) and funded by federal and state government. AWI focuses on polar and marine research in a variety of disciplines such as biology, oceanography, geology, geochemistry and geophysics thus allowing multidisciplinary approaches to scientific goals.

Background

Remote sensing of sea-ice thickness is gaining importance in polar climate assessments and operational sea ice forecasting. The evolving observational capability is based on an expanding number of satellite altimeter missions with a variety of altimeter implementations (pulse-limited radar, synthetic aperture radar, and laser altimeter). The main objective of the position is to take advantage of this unprecedented altimeter data coverage of the global sea ice cover and to develop the next generation sea-ice thickness retrieval algorithm for operational and completed satellite missions. Advances in sea-ice thickness remote sensing will result in improved process understanding of sea ice both hemisphere, enable more reliable sea ice forecasts and improve evaluation of numerical sea ice models. Open and free access to remote sensing data sets is our priority and essential for advancing climate research. Therefore, all results will contribute to decadal climate data records generated in collaboration with international colleagues in the ESA Climate Change Initiative sea ice project and the Copernicus Climate Change Services.

Tasks

  • Improving sea-ice thickness retrieval algorithms based on data of satellite radar and laser altimeter mission (ERS-1/2, Envisat, ICESat, CryoSat-2, AltiKA, Sentinel-3A/B, ICESat-2) using physical and machine-learning approaches;
  • Implementation of algorithm improvements in the python sea ice radar altimetry toolbox (pysiral);
  • Quality control of remote sensing data with validation data sets from research aircraft and moored/tethered sensor platforms;
  • Support production and quality control of sea-ice thickness climate data records within ESA CCI sea ice project and Copernicus Climate Change Services (C3S);
  • Evaluation of variability of sea-ice volume and trends in the past 3 decades;
  • Presentation of results in scientific journals and international conferences.

Requirements

  • PhD in natural sciences, mathematics, informatics or computing (very good or excellent marks);
  • Experience in computing environments and processing of large data sets;
  • Proficiency in the python programming environment;
  • Good English in written and spoken form;
  • Proven experience in publishing papers in the peer-reviewed scientific literature;
  • Proven ability to work in teams.

Additional advantageous knowledge and skills

  • Background in sea ice remote sensing and/or data science;
  • Hands-on experience in machine-learning methods;
  • Experience with Unix environments;
  • Experience with project management;
  • Willingness to participate in field-going expeditions with the aim of collecting ground truth data for algorithm development and quality control of remote sensing products.
