Abstract:
In 2012, ENVISAT mission was interrupted, after 10 years of altimetric measurements over ocean.
Five years later, the mission’s historical database is still maintained, studied and used as a reference. After a first reprocessing (V2.1 in 2012), data are reprocessed once more to remain in line with the current altimetric missions such as AltiKa, Jason-2 and 3 or Sentinel 3.
Improved at several levels, the new data set include a tenth of algorithm improvements: instrumental corrections, SWH look up tables, improved wet tropospheric correction, GDR-E orbits, new tide models…
Level 2 production started in July 2017 and the whole dataset will be delivered to users after complete validation, in early 2018. At almost mid way of the complete series validation, this poster gives an overview of the future dataset and anticipates the expected impacts on data for several scales : climate, mesoscales, coastal areas, high latitudes,...
