Originator: Same
Original Data: Unconfirmed
Instrument Type: FUESS (1963-1972), LFT-4 (1973-1986)
Digitized Interval: Unconfirmed
Present Data: Hourly, daily, and monthly values obtained by:
Hourly: Unconfirmed
Daily: 119-point convolution filter (Bloomfield, 1976) centred on noon applied to the hourly data with respective periods of the 95, 50, and 5% amplitude points at 124.0, 60.2, and 40.2 hours
Monthly: Simple average of all daily values; calculated if 7 or fewer days are missing
Span of Data: 01 January 1963 - 31 December 1986
Gaps > 1 Month: 01 January - 31 December 1964, 31 Auguat - 02 December 1982
Time Reference: GMT (hours 00-23)
Space-filler Flag: -9999
Units: Millimeters
Missing Data Flag: 99999
Reference Level: All data are referred to tide gauge zero and linked to historic fixed bench marks.
Comment: The daily or monthly means do not reveal any obvious reference level shifts. The data contain significant energy of 1 to 5 day periods related to atmospheric and oceanographic events. The monthly means show a linear increase of about 1 cm per year.
