Abstract:
CORA (Coriolis Dataset for ReAnalysis) is a delayed mode validated global temperature and salinity dataset provided by the Coriolis data center. This dataset provides measurements from 1950 to 2014 and is used for the model reanalysis provided by the copernicus marine service (http://marine.copernicus.eu/).

Various new datasets have been added to CORA to enhance the ocean data coverage in the 4.2 version. Among them, the french SHOM (Service OceanorapHique de la Marine) have provided more than 3 million original profiles on the period 1950-2009.

The delayed mode data validation is based on two sets of tests. Airst, an automatic test set able to detect and flag obvious erroneous measurements. A second set of tests is based on the comparison of measurements with a minimum and a maximum temperature and salinity reference field. A warning is associated to each suspicious profile which is manually checked by an oceanographer.

The next objective of CORA is to produce a copernicus CMEMS dataset by merging the best features of the CORA dataset and EN.4 datasets (www.metoffice.gov.uk/)
