Consistency checks of DM salinity corrections
An additional review of basin-wide data quality has been regularly performed at the regional level (North Atlantic-ARC and then Atlantic ARC) since 2013. One of the objectives is to ensure that the delayed mode salinity corrections are consistent within the basin. These checks are necessary because delayed mode analyses are conducted by different operators from different national data centres and because procedures, knowledge, and reference datasets have evolved since the beginning of the Argo project.
Method
For each float processed in delayed mode in the A-ARC region, we use a modified OW method using four different sets of configuration parameters and the latest available reference data set. Compared to the original OW method (Owens and Wong, 2009), our modified method better takes into account interannual variability and provides more realistic error bars (see Cabanes et al., 2016).
We only check the DM salinity correction of a float if the results obtained for the four configurations differ significantly from the correction applied by the float's PI. We are then able to isolate a small number of floats for which salinity profiles are examined in more detail: sections along the float path, comparison of some profiles with the closest reference data or with the closest real-time argo data, if necessary. Finally, when we consider it necessary, we warn the PI or DM operator of the float and suggest that they modify the salinity corrections. The reports are available here.
