Session: Science IV: Altimetry for Cryosphere and Hydrology

Presentation type: Type Poster

With the launch of Sentinel-3A (2016) and Sentinel-3B (2018), the Copernicus programme has a constellation of two SAR altimeters, which provides an operational access to inland Water Surface Height (WSH) data (i.e., lakes and rivers), with outstanding product performance and data coverage.
To further improve the performance of the Sentinel-3 Altimetry LAND products, ESA is developing dedicated and specialized Level-1 and Level-2 processing chains for all S3 Altimetry Land surfaces, i.e., over Inland Waters and Cryosphere. The so-called Thematic Instrument Processing Facilities (T-IPF) are developed by ESA for the processing of (1) Inland Waters, (2) Sea-Ice, and (3) Land Ice areas.
The new T-IPFs are currently under development with an intended deployment by Q4 2021. The T-IPF’s will include specific evolutions, with in particular the implementation of Hamming and Zero Padding to the Delay Doppler processing for inland water surfaces. These evolutions will improve water level accuracy in the Level-2 Inland Water data product. The coverage of the respective Thematic Data Products will be limited to the respective thematic area, defined by S3 land thematic mask.
The Sentinel-3 Validation Team (S3VT) is an international team of leading scientists and engineers – regularly meeting every year – that works in the assessment and the Cal/Val of the Sentinel-3 data products, through field experiments and comparisons. In this frame, all valuable and relevant activities made over inland waters are presented and discussed. The benefits for experts interested in joining the Sentinel-3 Validation Team community will be explained, as well as the procedures to become a member of this dynamic community. Proposals of new validation activities are very welcome and can be submitted.
