Quality Assessment by the UH Sea Level Center

Comment

The daily and monthly values do not reveal any obvious reference level shifts or trends and agree well with Acapulco except for a possible shift of about -8cm between 08 June - 06 July 1955 and also between 29 October - 19 November 1955. These questionable level shifts do not appear to affect the long term reference level stability. The timing is good for most of the series.
