Category: News of the other missions

New Along-track Sea Surface Heights Level-2+ (L2P) products are now available for Copernicus Sentinel-3B.

We are pleased to inform you that the Along-track Sea Surface Heights Level-2+ (L2P) products are now available for Sentinel-3B. These mono-mission products contain along-track corrected sea surface heights with respect to a mean sea surface, corrections and geophysical parameters. The last versions of altimetric standards are used and there is a homogenized format for all satellites.

These new products are processed by the Sentinel-3 L2P/L3 Marine Altimetry Service (CNES/CLS), in the frame of a EUMETSAT contract, part of the COPERNICUS Programme funded by the European Union. 

The products are available in Near-Real Time, Short Time Critical and Non Time Critical, and the service is operational. 


Sentinel-3B L2P are disseminated by AVISO+ (via ftp or AVISO+ CNES Data Center) and NRT/STC products will also be disseminated in the near future by EUMETSAT via EUMETCast.
