Oxygen real-time quality control
Since November 2012, a real-time QC is applied to Argo floats oxygen data
Argo floats report oxygen in an homogeneous way as– DOXY : micromole/kg
– The oxygen calculation is documented on :http://www.argodatamgt.org/Documentation
Groom-gliders Trieste data-management meeting
Trieste, June 2013
Oxygen real-time quality control
An equivalent quality control will be tested on Glider oxygen data
According to that study, the following settings may be applied for oxygen real-time QC– Global range : -0,5 to 600 micromole/kg– Spike : 100 micromole/kg– Gradient : 100 micromole/kg
