TXT file format for REFMAR tide gauge data available on http://data.shom.fr

TXT is one of 3 REFMAR tidal data dissemination formats available on data.shom.fr. This format is the simplest of the 3. It is composed of a header summarizing the essential information about the tidal observatory and the observations and data as such (one sea level measurement per line).

 

Header:

This block contains all the information regarding the sea level observations. Each line starts with a "#" symbol. The following example shows the information for the port of Brest.
