Trans. : No Distribution : 1984-2004 Refernce Levl: The sea level heights are referred to the zero point assigned to the tide staff, which is 3.073 m under bold on building. Several reference level shifts were identified. They were temporarily adjusted based on analysis of hourly residuals, daily plots, and comparison of daily values with regional stations. The originators may provide more precise corrections if supporting information is available, at which time the series will be updated. yyyymmddhh - yyyymmddhh added to original (mm) ----------------------- ---------------------- 1984010100 - 1988123123 1250 1986103116 - 1987022616 300 1987123117 - 1988033118 -800 Comment : The timing quality is good for most of the record. The mean level appears about 200 mm high during Jun-Dec 1988. This feature is under investigation by the originators.
