Quality Assessment

Comments

All data have been compared with the current Harmonic Constants Library, and residuals checked. Records have been visually inspected for spikes, datum shifts and timing errors.

The data series contain many one hour gaps, usually once every seven days, but sometimes as often as one gap a day. Only gaps of over one hour are listed below.
