Documentation - date unknown

1937 - 1956 VALUES BASED ON HIGH AND LOW WATER READINGS

Documentation added 1991-06-11

Aden 485/001 RLR(1962) is 9.1m below BM PEO

Documentation added 2009-03-10

2007/8 one minute sea level data downloaded from the IOC Sea Level Station Monitoring Facility Ostend. This is then converted to 15min. data for processing. 2008 monthly and annual mean sea level values have now been extracted from the data. As the relationship for the prime bench mark remains the same there is no need to alter RLR. Details of the bench marks has been derived from site installation information. Copies of these have been included in the port files and RLR file for reference.

The historic data for Aden (1879-1933) has been reviewed. As a result the RLR factor for all of that period has been set to 5.141m

Documentation added 2016-01-22

A value of MTL-MSL=16 mm has been applied to the RLR data for the period 1937-1956 using harmonic constituents from the GESLA2 (high-frequency tide gauge) dataset.
