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.

Be aware that these data have not undergone any quality control. For standard engineering practise please use the full quality-controlled data available for download from the QC Data tab.

These wave files contain the full range of parameters available from a Datawell DWR MkIII wave buoy and an additional two wave parameters Energy Period (Te) and Wave Power (P).

A description of each of the wave parameters provided is available in the Wave Parameter Handbook on the Resources Page.
