Quality Assessment

Comment

The daily and monthly means do not reveal any obvious reference level shifts. Residuals are extremely noisy. Hence only spikes over 25cm have been flagged. Most questionable fluctuations are related to timing problems with the gauge.

The residual for the 1998 series is quite clean but the residual for 1999 reveals some minor timing errors throughout this year. The standard deviation channel (ESSSSS01) for 1998 and 1999 has been flagged suspect where values are over 30 m/s.

The completeness index (CI) is calculated for the primary sea level channel only.
