These wave data have undergone full quality control. Poor data is flagged, not removed. A summary of the flagging system is included in the table below.
Full details of the flagging and quality control procedures can be found in the Quality Assurance and Quality Control of Waves Data handbook.

| Flag | Suspect Parameters | Not Suspect Parameters | Description |
|---|---|---|---|
| 0 | Hs, Tz, Tp, Direction, Spread, SST | All data pass | |
| 1 | Hs, Tz, Tp, Direction, Spread | SST | Either Hs or Tz fail, so all data fail, except SST |
| 2 | Tp, Direction, Spread | Hs, Tz, SST | Tp fail + derivatives |
| 3 | Direction, Spread | Tp, Hs, Tz, SST | Direction fail + derivatives |
| 4 | Spread | Direction, Tp, Hs, Tz, SST | Spread fail |
| 5 | Not used | ||
| 6 | Direction, Spread | Hs, Tz, Tp, SST | Re-processed due to breaking waves |
| 7 | Hs, Tz, Tp, Direction, Spread, SST | Buoy off location | |
| 8 | SST | Hs, Tz, Tp, Direction, Spread | SST fail |
| 9 | Hs, Tz, Tp, Direction, Spread, SST | Missing data | |
