Originator:
Same
Original Data:
Analog
Instrument Type:
Stevens Model A float and well gauge with a Telog Instruments Model R-2108 potentiometric recorder connected to the sprocket wheel.
Digitized Interval:
1 second
Present Data:
Hourly, daily, and monthly values obtained by:
Hourly:
Average of 3600 1-sec samples per hour.
Daily:
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.
Monthly:
Simple average of all daily values; calculated if 7 or fewer days are missing.
Span of Data:
23 March 1992 - 23 April 1993
Gaps > 1 Month:
None
Time Reference:
GMT (hours 00-23)
Space-filler Flag:
-9999
Units:
Millimeters
Missing Data Flag:
99999
Reference Level:
The sea level heights are relative to a local (arbitrary) datum.
Comment:
The gauge is located on Lee Stocking Island. The daily and monthly means do not reveal any obvious reference level shifts. The timing of the hourly values is good.
