Hi John,
We have now constructed a real netCDF file for you to check. QC flag
variables have been added in. The QC flagging method is based on the
proposed IODE scheme in (1) below.
Attached are the sample .nc file, text (ncdump) of same and a document
specifying the CDL.
Thanks and Regards,
Andrew Walsh
