Quality The hourly data, as received from the tide stations, are inspected and
obvious errors such as data spikes and time shifts are corrected.
Gaps less than 25 hours are interpolated. Reference level problems are
referred back to the originator. If the originators can not resolve
the reference level shift, comparisons with neighboring sites or
examination of the hourly residuals may warrant an adjustment.
Descriptive station information and quality assessments are prepared.
