Postdoc in the field of InSAR, applied to Ice Velocity measurement - DTU Space

Updated: 3 months ago

Do you want to work within the field of Synthetic Aperture Radar Interferometry (InSAR) for the measurement of Ice Velocity (IV) at the Microwaves and Remote Sensing division? Then we have an opening as postdoc at DTU Space, Technical University of Denmark (DTU).

We offer you an opportunity to be part of a broader project, concerning an improved modelling of polar ice-sheets, based on a variety of satellite data, and their contribution to sea-level rise. The project is funded by a grant awarded by the Novo Nordisk Foundation to Prof. S. Abbas Khan, which has led to the establishment of the Center for Ice-sheet and Sea-level Predictions (CISP) at DTU. 

You will be a part of the CISP team, and will be involved in InSAR-based IV measurements for several areas of interest, both in Greenland and in Antarctica, and in their subsequent interpretation and modelling.  You will also contribute to other ongoing projects in the division, such as the ESA-funded Greenland- and Antarctic Ice Sheet Climate Change Initiative projects, and the Danish PROMICE (Programme for the Monitoring of the Greenland Ice Sheet).

Your main tasks will be

  • To design, develop and validate methods for InSAR phase-unwrapping error characterization, using Artificial Intelligence approaches;
  • To design, develop and validate procedures to fuse IV measurements derived using different techniques and sensors, for ice-sheet wide mapping applications;
  • To collaborate with the CISP team, concerning interpretation and modelling of IV measurements;
  • To contribute to the international research community in this field, by presenting relevant results at international conferences and workshops and by publishing in high-impact peer-reviewed journals.

Your qualifications must include a PhD degree (or equivalent) within a relevant research area, as well as a two-year master's degree (120 ECTS points) in Engineering or Physics, or a similar degree with an academic level equivalent to a two-year master's degree.

Furthermore, we require that you have experience with InSAR.

More about InSAR
Synthetic Aperture Radar Interferometry (InSAR) provides more accurate Ice Velocity (IV) measurements, and a higher spatial resolution, compared to the routinely used amplitude-based and optical data processing methods. The systematic use of InSAR has not only the potential of improving the quality of current IV products, but it also has recently been proven to be a formidable tool to observe sub-glacial drainage events, which can in turn improve our understanding of ice-sheet hydrology, and thus our ability to model ice-flow. 

The EU/ESA Sentinel-1 SAR missions are generating an unprecedented data archive for polar applications, making it possible to systematically generate Ice Velocity (IV) maps for both Greenland and Antarctica, and further contributions are expected from forthcoming missions, such as the NASA/ISRO NISAR satellite.

Despite InSAR being a well-established technique, its operational use for routine IV measurements is currently limited, and further research is required to reliably fuse InSAR-based retrievals, with those available from other techniques and sensors.
