The real-time quality controls performed on Coriolis floats data (and other types of platforms) are described in the "Argo quality control manual".
Coriolis DAC recently changed its implementation of the test 14: density inversion.
Since 2001, we used in-situ density. On October 10th, we started to:
- Use potential density instead of in-situ density
- Apply a tolerance of 0.01 kg/m3 to detect an anomaly inversion
The 0.01 kg/m3 tolerance applied by Coriolis DAC is not an Argo rule. A work is underway to define accurately the density inversion test 14 and its tolerance; it should be presented during the Seoul data-management meeting.
