Estimating accuracies of tidal datums from short term observations

This paper develops multiple curvilinear regression equations that estimate the accuracy of computed 19 year equivalent tidal datums at tide stations with one or more months of data. These regression equations are simple to use, quantitative, and consider individual station characteristics. The parameters affecting the accuracy of the computed tidal datums are discussed along with the relative accuracy of the standard method and the alternate method of simultaneous comparison. A. Nicholas Bodnar. "This report is the culmination of applied research in datum error estimation performed by former NOAA employee, A. Nicholas Bodnar in 1981. The methodology developed in this work for estimating errors has been operationally adopted to estimate individual tide station datum errors by NOAA/CO-OPS for several applications. It has been used in identifying gaps in the National Water Level Observation Network for estimating datum errors in the tidal models used in the NOAA VDatum tool and will be used to provide users information on datum uncertainty on the NOAA web site. We are publishing the final draft report in its original form provided by the author back in 1981"--Page iii. "March 1981." "Published August 2014"--PDF cover page.
