During the last 20 years, altimeter high quality near real time and delayed time Level3 (along-track cross-calibrated SLA) and Level4 products (merging multiple sensors) were developed in parallel with Level2 (a.k.a [O/I]GDR) processing improvements. Directly usable and easier to manipulate, L3/4 products are vastly used and contribute to various studies in different fields, from climate and meteorological phenomena, to geophysics and biology.
In early 2014, many changes have been implemented in the products and processing, impacting both along-track and gridded products. A full reprocessed dataset of the 20 years of altimeter measurements, including all of these changes, has been delivered in April 2014.
The quality of these datasets was estimated in different part of the ocean by comparison with independent measurements. We present here the reprocessed dataset and its consistancy with independant measurements.
