Abstract:
Since 2013, the SARAL is delivering high quality sea surface topography measurements including during its drifting phase, started in July 2016,.
We present the current Cal/Val status of the SARAL/AltiKa mission over ocean, mainly from GDR data using Patch 2 version, and IGDR data over the drifting phase. The main data quality metrics are presented (data availability, SSH differences at cross-overs) and demonstrate that the mission is still in excellent shape.
The results of efforts to improve SARAL/AltiKa data are also presented. We estimated a preview of SARAL’s future Patch 3 performance. This Patch-3 like data will feed the next generation of multi-mission products (CMEMS/AVISO). Investigations were also performed on the Ka ability to map differently the oceanic content, notably influencing the relations between significant wave height and topography measurements.
