attribute NC_GLOBAL quality_control_level String Research Quality
attribute NC_GLOBAL quality_control_method String The quality assessment is mostly based on the residuals (observed data minus predicted tides) of the hourly data. This assessment also applies to the daily and monthly data since they were derived from the quality-controlled hourly data. The following corrections are made to the hourly data prior to this assessment: 1) Gaps or obviously wrong data points in a span less than 25 hours are filled by the predicted tide method*. 2) Timing errors of exact increments of an hour are corrected by shifting the data. 3) Reference level shifts are only corrected after information from tide staff readings or comparative readings with a fixed bench mark are checked to verify that the shift was not a natural event. If comparative readings are missing or incomplete, comparisons of the data with nearby stations may warrant the adjustment of some obvious shifts. 4) Data with unresolved datum shifts are not disseminated. However, if sufficient time spans of data are available before or after the year(s) with the unresolved shift(s), a subset of quality assured data is made available. Thus, the Span field in the Quality Assessment may not match the span of the distribution data set. As the questionable datum shifts are resolved, the data set will be updated. Although this policy adds some complexity, it allows more rapid dissemination of at least the quality assured years. Note : If the predicted tides poorly model the observed heights due to the inability of the tidal analysis to completely resolve the non-linear shallow water effects, the residuals are not (observed data minus predicted tides) of the hourly data. This assessment also applies to the daily and monthly data since they were derived from the quality-controlled hourly data. *The predicted tides are obtained with the use of a harmonic analysis program (Foreman, 1977) which is executed on a year of apparently good data for a given station. The Predicted Tide Method for filling gaps consists of statistically comparing the predicted tides to the observed data and shifting the predicted tides in time to correct for timing differences. Then the linear interpolation between hourly values at the end points of the gap in the residual series is added to the corresponding corrected predicted tide data to obtain interpolated values over the span of the gap.
