Reference level

All heights have been referred to the station Tide Gauge Zero which is linked to fixed bench marks. However, further analysis of the data has lead to adjustments of the reference level in separate segments. The following adjustments were justified by obvious shifts in the hourly residuals. These adjustments are uncertain to a few centimeters.

Period ((hour)day/month/year) Value Added to Original(mm)
(15)31/12/67 - (14)29/02/68 -300
(02)06/03/72 - (06)12/03/72 300

The station was relocated to latitude 28° 22.9' N, longitude 129° 29.8' E on 16 December 1980. However, the bench marks of the original and new locations have been linked by levelling.

Quality assesment

Comment

The daily or monthly means do not reveal any obvious reference level shifts and agree well with a neighboring station Naha except for a possible datum shift of +25cm on 30 April 1969. Most questionable fluctuations are related to timing problems with the gauge.
