Links from RLR data to geocentric heights

5 December 2016

As a result of our ongoing work with Système d'Observation du Niveau des Eaux Littorales (SONEL) we are now able to offer information about the geocentric height and vertical rate of movement of some tide gauges. These estimates are dependent on linking the tide gauge's primary benchmark with the GNSS receiver through levelling. As a result, these are currently only available at small subset of stations.

The details of the link are shown on the station's RLR diagram page (for example, at Newlyn). A fuller description of the work is available here.
