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.
