5 CREWSS Flagging Criteria “Quality Control is half science and half art.” - Scott Prosise “Quality Control is half science and half art.” - Scott Prosise

6 History file shows 77.7W entered instead of 7.7W

7 Update from OPC

9 Future Opportunities Anthony.Siebers@noaa.gov Christine.Schultz@noaa.gov

10 Auxilliary Slides

11 The following slides were generated by Scott Prosise, OPC Senior Marine Forecaster and step through the QC process

12 Starting the QC Session – Global view

13 Menu Options

14 Going to the first observation …

15 Observed Model Difference

16 Keep or Reject Parameters QC Progress

17 History file shows 77.7W entered instead of 7.7W

18 10 day history

19 Most common human error: Geographical 37N became 77N !

20 Means Another digit transposition 42.6N instead of 24.6N

21 Observation “repaired” and data saved

22 Ship GBTT is flagged for being 4.3 mb too high, … but is it?

23 NO! The history file reveals that the Queen Elizabeth 2 is a reliable observer. So…

24 The QE2 gets a “keep” flag and the model is told to analyze for the data.

25 Data from buoys … Not always perfect, but usually very reliable Average 40+ obs per day Mean of < 1.0
