CORA (standing for Coriolis Ocean database ReAnalysis) is a global oceanographic temperature and salinity dataset produced and maintained by the French institute IFREMER. Most of those data are real-time data coming from different types of platforms such as

research vessels A research vessel (RV or R/V) is a ship or boat designed, modified, or equipped to carry out research at sea. Research vessels carry out a number of roles. Some of these roles can be combined into a single vessel but others require a dedicated ...

. The latest version of CORA product is v3.3, it covers the years 1990 up to 2011 and has been released in July 2012. Observations are profiles distributed on measured levels (pressure or depth) and organized by dates of measurement and type of platform. Main users of CORA dataset are ocean modelers who needs to constraint and initialize their model. CORA is free of access and can be download via CORIOLIS website in netCDF file format. The main different of CORA dataset with other available datasets is that CORA provides data at depth levels where measurements were made rather than at standard levels such as in World Ocean Atlas o
ENACT3
In addition data in CORA are retrieved from Coriolis database where each profile is visually checked by specialist operators if suspicious.

Validation procedure

Validation in database

* duplicate observation check * automatic checks (spikes, climatology, monotonic depth, valid date/position,...) * objective analysis (ISAS software with 21 days, 300 km covariance ray): suspicious observations are visualized by an operator

Validation post extraction

* second duplicate observation check (detection and choice parameters tuned) * refined climatological test * XBT depth correction * second objective analysis with tuned parameters: anomalies are visualized * ARGO special diagnostics

Data sources

The CORA dataset is designed for operational oceanography, so most global real time monitoring networks are plugged into this database. The data sources are the following: * ARGO (autonomous drifting profilers) * The global network of moored buoys comprising the TAO/TRITON, PIRATA and
