Benchmarks

Reference Level

All heights have been referred to the station Tide Gauge Zero (TGZ) which is linked to fixed bench marks.

Tide Gauge Benchmark (TGBM) Description

Japan Meteorlogical Agency Benchmark bolt inside tide gauge hut, adjacent to stilling well

Auxiliary Benchmarks

Tide station Benchmark 3.3006m above Tokyo Peil (1969).

Parameter Code

ASLVZZ01 - The elevation of the sea surface to a known datum, measured in metres.

Quality Assessment

The daily or monthly means do not reveal any obvious reference level shifts. Prior to 2001 most questionable fluctuations are related to timing problems with the gauge. Data spikes of about 10cm or less have not been corrected.

Completeness index (CI)

Sea level data from Japan is processed for each year. Occasionally data is missing from the data sets, either because the data set does not cover the whole year or because data has been flagged null. The number of cycles in a year with no missing data is calculated (based on the sample interval and whether a leap year). The completeness index calculates what proportion of the data expected in a year is present and not flagged null.

Quality index (QI)

During processing cycles considered suspect within a series are flagged M. The quality index calculates what proportion of the data available is not considered suspect.
