Additional information
Other relevant informationBackup gauge on site: Handar encoder ADR (Nov 82-)
Daily values calculated using 119-point convolution filter (Bloomfield, 1976) centred on noon applied to the hourly data with respective periods of the 95, 50 and 5% amplitude points at 124.0, 60.2 and 40.2 hours.
PSMSL also hold data from another gauge 710/030.
