=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 2002Sep24 : A description of the sea level network in Finland can be found in 'Operational Oceanography: Implementation at the European and Regional scales. 2002 (pp.129-137)'. 1883-1921 FCODE=01 1922-1970 FCODE=06 =========================== FOLLOWING PSMSL DOCUMENTATION ADDED 11-JUN-91 : Vaasa/Vasa 060/051 RLR(1964) is 8.0m below BM1139G =========================== BENCHMARK INFORMATION UPDATE ADDED 12-JUL-93 : Vaasa/Vasa 060/051 RLR(1964) is 8.0m below BM1139G =========================== FOLLOWING PSMSL DOCUMENTATION ADDED 09-Jan-2012 : Levelling information recently supplied by the Finnish Meteorological Institute confirms that previous benchmark 1139G is no longer used. From 2000 onwards Primary benchmark is 00003 3.294 above gauge datum. While this was being reviewed it was noticed that data for the period Jan1919-Dec1921 was not included as RLR leaving a gap in the RLR dataset. Although this was investigated no reason was found for this anomaly. This data period has now been included in the RLR dataset. =========================== FOLLOWING PSMSL DOCUMENTATION ADDED 31-Jan-2017 : Following the 2016 levelling exercise some adjustments have been made to the benchmark reference heights - at Vaasa this was +1mm for BM 00003. 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.
