9 years ago CDIP Quality Control Procedure Examples
CDIP’s Quality Control procedures have been written up here. http://cdip.ucsd.edu/?nav=documents&sub=index&units=metric&tz=UTC&pub=public&map_stati=1,2,3&xitem=proc#quality Please note that our QC procedures have been an evolution for over 35 years and in it’s current form you can consider it as going though several layers/stages.
- Realtime QC tests are listed in http://cdip.ucsd.edu/?nav=documents&sub=index&xitem=proc&xdoc=qc_table
- This table has descriptions associated with each test and some have pictures and examples.
- Depending on the sensor type some tests apply some do not. The table should help clarity.
- All errors are logged, some emailed, and depending on the severity, some events are paged to someone who’s on call 24/7.
- Attached you should find some documents on our NetCDF qc and flagging.
- Also attached is an actual error log from one of our buoy stations.
- Once a month all our station data is automatically reprocessed. Visual inspections are also performed.
- When a buoy’s logger card is recovered the data is reprocessed again, visual inspections are performed, and netcdf files generated with qc flags.
All exceedances of thresh hold errors receive visual (human) inspections daily, if needed, not just at the end of the month.

The RA DAC managers are collectively discussing quality control test and procedure implementations, and thus I have been looking at some of the links you have sent me previously. The team is looking for how qc tests have been applied by others. The following comments represent examples from different organizations, federal and regional, of different applied quality control procedures.
