From Level 2 to higher level water height products for hydrological applications
Event: 2016 Ocean Surface Topography Science Team Meeting
Session: Science III: Two decades of continental water's survey from satellite altimetry - From nadir low-resolution mode to SAR altimetry, new perspectives for hydrology
Presentation type: Type Oral
This paper aims at showing the preparatory activities which have already been initiated at CLS and LEGOS. At the different levels of the chain, processing algorithms are evaluated, compared and their performances are assessed. Several datasets (Jason-1, Jason-2, Jason-3, Cryosat-2, Saral and Sentinel-3) are integrated in order to enable efficient cross-calibration of the various missions and merging all measurements into densified higher level products. Additional information derived from the exploitation of the water masks are also used in the processing chain.
In this context, we propose to give an illustrated overview of potential of the altimeter constellation and its performances for hydrological applications, taking benefit of the synergy and complementarity between the different altimeter missions.
