Quality Assessment by the UH Sea Level Centre

Comment

The tidal analysis was unable to resolve all the harmonic constituents in the data thus the hourly residuals contain uncertain periodic signatures. The daily and monthly means reveal no apparent changes in the reference level and agree well with Majuro. The data quality is good. This series is distinguished from Pohnpei-A because the two series are not linked to the same tide staff zero.
