| Popis: |
Since the launch of the Sentinel-3A satellite in February 2016, a new long-term series of Delay-Doppler/SAR altimetry SSH measurements over global ocean has begun with better spatial resolution of the signal in the along-track direction and improved noise reduction through multi-looking. Data from an experimental mode, the so-called LR-RMC mode, are also available from the CNES S3PP prototype with a processing of the S3A data that differs from the classical SAR-mode processing in numerous ways. In-parallel, Jason-3 and now Sentinel-6/MF missions continue the long-term record of SSH measurements started in 1992 by the Topex-Poseidon satellite in the conventional low-resolution mode (LRM). In support of these various high-precision SSH measurements, SSB corrections need to be computed/adapted to each of these specific measurement modes to accurately correct all these range measurements for the sea-state effects because of its empirical nature. In this poster, we will compare the different SSB solutions to document the range/sea-state relationships from these different measurement modes. |
