PRIOR TO 1977 GAUGE AT 64 42 N, 24 30 E CLAIMED CONNECTABLE
This station was formerly known as Hornankallis in the Publication Scientifique.

Documentation added 2012-01-04

From levelling information supplied by the Finnish Meteorological Institute
gauge site lat. and long and BM details as follows:
1922-1976 64 42 24 30 1294Y
1977-1996 64 39 24 25 83151
The above two benchmarks refer to the old tide gauge.
1997- 64 40 24 24 92409 (1992)
95403 (1995)
It was decided to refer to 92409 (1992) as the Primary Benchmark as it also
appears in the levelling report for 2006 whereas 95403 (1995)does not.

Documentation added 2017-01-31

Following the 2016 levelling exercise some adjustments have been made to the benchmark reference heights - at Raahe this was -1mm for BM 95403. The adjustments are a result of more accurate measuring and calculations using the N2000 height system. The RLR diagram has been re-drawn because of this.
