Sentinel-3A & 3B Corrected Sea Surface Heights product

The products, called L2P SLA in short, 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.

They are mono-mission products containing 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. The product format is netCDF.
