Hello, the data is now available for CCI-v4 !
30+ years of satellite data (from altimeters and SARs), with most of it retracked (lower noise, better coastal coverage), inter-calibrated (values consistent across the dataset) and denoised! (or not, the original values are still there with noise included)
You can find it here on ftp:

NB: for some altimeters (J3, S6), completion is under way in this version 4 and files will be added in the coming weeks.
We know it is a bit cludgy so a subsetting interface will be available soon.
There will be a version 5 next year (which will include much lower noise for ERS1 and ERS2, and also Sentinel-6).
All the best,
Fabrice
