CORA dataset

CORA3.2 2012 July Sea Surface Temperature

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 (research vessels, profilers, underwater gliders, drifting buoys, moored buoys, sea mammals, opportunity ships, ...).

Description

This MERCATOR-océan[1] is a privileged partner of CORA dataset since feedbacks from models assimilation (meteorology) are used to check suspicious profiles found thanks to innovation computing. CORA[2] is free of access and can be download via CORIOLIS website[3] in netCDF file format. The main different of CORA dataset with other available datasets is that CORA gives the data on the levels where measurements have been done rather than standard levels such in World Ocean Atlas or 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)
  • raffined climatological test
  • XBT depth correction[4]
  • 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:
