Comments
The daily or monthly means do not reveal any obvious reference level shifts except for the following:
- A slow drift in datum upwards over the months August to October 1989. Possible datum shift of approximately -100cm on 13 October 1989.
- From 01 January 1990, datum of data seems to have been shifted by approximately +100cm.
- Possible datum shift of approximately -50cm between the gap 12 May and 27 June 1991.
- Possible datum shift of approximately +20cm on 17 September 1993.
Time shift of +17 hrs applied to 03/06/92(02) - 08/06/92(10). Most questionable fluctuations are related to timing problems with the gauge.
