The Copernicus Marine Service provides regular and systematic reference information on the physical state and on marine ecosystems for the global ocean and the European regional seas (temperature, currents, salinity, sea surface height, sea ice, marine optics, nutrients, etc.). Products are built using Satellite and In situ observations as well as ocean numerical models including the description of the current situation (analysis), the prediction of the situation a few days ahead (forecast), and the provision of consistent retrospective data records for recent years (re-analysis).
We provide here with global and regional on-line validation of sea surface height and derived data from altimetry observation by satellite, for products developed in the frame of the Sea Level Thematic Assembly Center contract.
