Use IQuOD data in place of WOD data

[BecCowley]

Currently all our build is done on the WOD dataset. Eventually, we aim to use IQuOD in place of WOD.

IQuOD is the WOD but with uncertainties, QC flags output from a community agreed QC toolkit and intelligent metadata that improves guesses of XBT probe types where this metadata is missing.

For CARS, the biggest benefit is the QC flags and potentially uncertainties.
As of September, 2023, the IQuOD files with AQC flags are not available publicly, but some files have been produced for testing by myself. They are available on an S3 bucket and for download.

Issues:

• Reading from the s3 bucket is slow (operating out of the Bowen storage area)
• Downloading the files is possible - where best to do that to?
• Would it be quicker to download and operate from local files, perhaps to Bowen storage, perhaps the NCI virtual desktop?

Have downloaded the IQuOD files to /oa-decadal-climate/work/observations/CARSv2_ancillary/IQuOD
Installed aws cli to my local directory
command to copy:
aws s3 cp s3://wod-collaboration/iquod/netcdf . --recursive --no-sign-request

Have also copied to gadi scratch/er50 to practice using the NCI interactive session tools.
