Argo delayedmode salinity QC procedures

Argo delayed-mode salinity QC procedures
Float salinity that are deemed by RT to have a
good relative vertical profile (ie. PSAL_QC
1, 2, 3) are put through the DM process. Float
salinity that are deemed bad by RT (ie. PSAL_QC
4) are not adjustable, and thus do not go
through the DM process.
Manual evaluation to detect anomalies on the
relative profile, such as spikes, that are not
detected in RT.
Adjustable float salinity.
Unadjustable float salinity.
PSAL_ADJUSTED original value PSAL_ADJUSTED_ERROR
FillValue PSAL_ADJUSTED_QC 4
