12.07.2023 New on AVISO+: Barystatic and manometric sea level changes from satellite geodesy
The barystatic and manometric sea level changes represent the mass component of sea level changes at global and regional scales respectively. They are estimated here using two different approaches: from satellite gravimetry and...

The Cruise LGD2308 left Taiwan onboard the ship Legend to measure sea surface heights and detecting oceanic eddies using GNSS for Swot validation (June 23 -July 3, 2023)[more]
30.06.2023 SWOT L2_NALT_O/IGDR and L2_RAD_O/IGDR Release
The Surface Water and Ocean Topography (SWOT) project is pleased to announce the public release of Level 2 science data products from the onboard nadir altimeter (NALT) and advanced microwave radiometer (AMR). [more]
22.06.2023 El Niño’s back in 2023
Altimetry sea level anomalies have been showing an elevation all along the Equator in the Pacific for the past four months.[more]
22.06.2023 Monitoring of the Kakhovka reservoir/river by altimetry
The Hydroweb database – https://hydroweb.theia-land.fr/ – is monitoring changes in water levels over time on large lakes, reservoirs and rivers, from altimetry measurements. Hydroweb was not originally designed to monitor...[more]
