Sažetak
The retrieval of the three geophysical parameters – sea surface height above the reference ellipsoid (SSH), significant wave height (SWH) and wind speed at 10 m above the sea surface (U10) – is the main goal of satellite altimetry and of primary importance for climate research. The Synthetic Aperture Radar (SAR) altimetry is expected to provide improved precision and along- track resolution compared to the conventional low- resolution mode (LRM) radar altimetry. CryoSat-2 enables a quantitative comparison of SAR and Pseudo-LRM (PLRM) data derived respectively from a coherent and an incoherent processing of the same SAR echoes. In this paper we perform their cross- validation and validation against in situ and model data to derive precision and accuracy at 1 Hz in open ocean, at distances larger than 10 km from the coast. The analysis is performed in the German Bight during 2011 and 2012.
