Delayed-Mode Quality Control (DMQC) - Australian Argo
What we do
CSIRO Marine & Atmospheric Research are the operators for
Argo Australia, which is a component of the Integrated Marine Observing
System IMOS. Argo floats
are deployed, real-time processed, and delayed-mode processed at CMAR.
Delayed-mode processing is carried out at least 6 months after data
has been collected. Under the direction of the lead scientist, a
rigourous and internationally standardised treatment is applied to
ensure the data is free of all detectable errors and biases.
What is here
The pages here are of most relevance to other members of the
international Argo community. They contain our processing diagnostic
materials and final reports for each float. Documentation of our
processing procedures will be added as it becomes available.
- QC material
- DMQC Notes contains Processing Reports
for each Australian float.
- CSIRO Float Manuals
links to the different float format types (with float serial numbers for each type) and electronic versions of the float user manuals.
- Check Plots leads to many different
categories of diagnostic plots. This material is not set up for browser
navigation - but is online for use by local staff and so that collegues can
be directed to material to share and discuss. However, a large portion of these
plots are available in the Processing Reports for each float, accessed via the

As well as usual analysis, new lists provide allow identification of files
with particular format problems, such as in PRES_ADJUSTED fields.
- 25 Nov 2011
Captures all progress made prior to ADMT12. Highlights problem
of missing or invalid ADJUSTED fields, especially in RealTime files. Also
identifies remaining problems with surface pressure parameter names in tech files.
- 1 Nov 2011
First audit based on Coriolis GDAC rather than GODAE. Also, now PROVOR
auto-correcting floats are expected to use a name indicating that condition, rather than
- 6 August 2011
Makes temproary allowance for PROVOR floats which are actually auto-correcting but use
- 22 Feb 2011
This version highlights remaining invalid surface pressure parameter names.
- 15 Jan 2011
Allowed different treatment of SOLO floats (for some just a temporary
allowance until parameter names resolved.)
- 18 December 2010
Audit code now detecting where more than one SP value is supplied for any
profile (a simple preference scheme determines which is to be used to
pressure correction.) Also using improved SP spike filter.
- 20 November 2010
Late Nov 2010 audit of tech and meta file formats, and treatment of
Surface Pressure correction and TNDP. Plots now indicate profiles where
PRES_ADJUSTED has not been loaded (black
instead of pink DM profile indicators.) Also, TNPD criterion modified slightly.

Surface Pressure correction and TNDP:

Oct 2010 audit, prior to ADMT-11, but using GDAC state as at mid September 2010:
