Sentinel-3 Hydrologic Altimetry Processor prototypE

The SHAPE project aims to prepare for the exploitation of Sentinel-3 data over the inland water domain (water heights and discharge)

• Characterise CryoSat-2 SAR data over inland water.
• Assess the performances, in Hydrology, of applying the Sentinel-3 IPF to CryoSat-2 data and emulating repeat-orbit Alti-Hydro Products (AHP).
• Analyse weaknesses of the Sentinel-3 IPF at all levels.
• Assess the benefits of assimilating the SAR/RDSAR derived AHP into hydrological models.
• Design innovative techniques to build and refine the L1B-S and assess their impact onto L1B and AHP.
• Improve SAR/RDSAR retracking over river and lakes.
• Provide improved L2 Correction (troposhpheric, geoid) for Sentinel-3 over land and inland water.
• Specify, prototype, test and validate the Sentinel-3 Innovative SAR Processing Chain for Inland Water.
