Data usefull for operational oceanography, are obtained by diverse means including in-situ (ships, drifters, floats, moorings, , etc) and satellites. They come in very different forms, from a single variable measured at a single point to multivariate, four dimensional collections of data that can represent data volumes from a few bytes to gigabytes. In past 10 years, we have seen the emergence of assembly centres that:
- integrate data coming from a wide variety of platforms and providers (including scientists, national data centres, satellite data centres and operational agencies),
- get enough information from the originators to be able to know exactly how the data have been acquired and processed (documented and commonly agreed QC procedures, history of the processing),
- and then distribute them in an agreed standard (speaking the same language).
Coriolis is one of these Data Assembly Centers that has originally been designed to provide the French ocean forceasting centers, MERCATOR-Océan and French Hydrographic Service ( SHOM), with real-time qualified and integrated products, first for assimilation and then for validation purposes. With the arrival of re-analysed products, such as CORA, Coriolis is also able to serve the research community.
