HYDROCOASTAL

Home | FAQ | Documents | Software | Products | Publications

HYDROCOASTAL is a project funded by ESA to maximise exploitation of SAR and SARin altimeter measurements in the coastal zone and inland waters, by evaluating and implementing new approaches to process SAR and SARin data from CryoSat-2, and SAR altimeter data from Sentinel-3A and Sentinel-3B.

New SAR and SARin processing algorithms for the coastal zone and inland waters will be developed and implemented and evaluated through an initial Test Data Set for selected regions. From the results of this evaluation a processing scheme will be implemented to generate global coastal zone and river discharge data sets. Case studies will assess these products in terms of their scientific impacts.
All the produced data sets will be available on request to external researchers, and full descriptions of the processing algorithms will be provided.

Latest news

First Test Data Set now available
The First Test Data Set is now freely available on request. It contains L2 outputs from the different candidate algorithms over the 18 test regions, and L3 time series for nine inland water regions. For more details go to the products page

Mid Term Review: 20/21 April 2022
The Mid Term Review was held as a hybrid face to face and online meeting at isardSAT offices in Barcelona.

Highlights were

  • Presentation of  SAR altimeter processing algorithms
  • Review and presentation of validation results to assess base performing algorithms for the coastal zone and inland water

Following this meeting, and after acceptance of the necessary deliverables (see documents page), Milestone 2 was successfully achieved.

Study examples

University of Bonn are working on CZ validation in this test site over the German Bight and Baltic Sea, showing Sentinel-3A ground tracks and locations of fiducial reference data from operational tide gauges of the BfG network (green triangle) and wave buoys (squares) and GPS stations (red dots):
