About us

Advancing research and monitoring of upper ocean processes and dynamics by synergetic use of satellite and in situ data.

Research Objectives

  • Strengthen the use of available satellite and in situ ocean observations for ocean monitoring, model validation, data assimilation, and prediction.
  • Support the development of future observing platforms by advancing the interpretation of satellite data in terms of geophysical quantities (like wind, wave, and current).
  • Exploit synergetic (complementary and overlapping) observational coverage to understand upper ocean processes and dynamics across all available time and space scales.

 

Targets and Priorities

  • Advance the understanding of  sea level variability: combined use of altimetry, gravimetry, in-situ data and modelling
  • Develop innovative radial surface currents estimation based on Doppler shift measurements from Sentinel-1
  • Advance the understanding of the mesoscale upper ocean dynamics based on satellite sensor synergy
  • Improve the sea ice classification
  • Develop techniques for thermal noise removal in SAR images
  • Improve data handling, visualization and analyses tools (include AI & ML)
