L2P products are netcdf homogenous along-track mono-mission inter-calibrated products, providing as much as possible the same updated corrections and models for all processed missions, in order to facilitate inter-mission comparisons. 

A new version 04_00 is disseminated by AVISO+ via FTP/SFTP and TDS (connect to MY AVISO+) for all missions and also on EUMETSAT Data center for Sentinel-6 MF mission.
