QUALITY ASSESSMENT OF SEA LEVEL DATA by the UH SEA LEVEL CENTER/NATIONAL OCEANOGRAPHIC DATA CENTER JOINT ARCHIVE FOR SEA LEVEL updated: 08 Mar 2023 Station : Burnie Latitude: 41 03.0S Country : Australia Longitude: 145 54.9E JASL # : 344A Time Meridian: 150E (GMT + 10 hr) GLOSS # : none Originator #: ID071005 NODC #: 34141501 Contributor : National Tidal Centre, Bureau of Meteorology PO Box 421 Kent Town SA 5071 South Australia AUSTRALIA Originator : same; Australian Baseline Sea Level Monitoring Project Original Data: digital Instrmnt Type: (1992-24/Jul/2009) Aquatrak acoustic gauge, Sutron Logger (SL) 24/Jul/2009- acoustic gauge Telmet T320 Aquatrak Controller (TAC); Digitzd Intvl: TAC: Weighted average of 4, 1-minute readings; 1-minute reading is average of 60, 1-sec samples SL: used 6-minute samples average of 181, 1-second samples. Present Data : Hourly, daily, and monthly values obtained by: Hourly : filter with a cut-off of 2 hours Daily : 119-point convolution filter (Bloomfield, 1976) centered 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 : 03 Sep 1992 - 31 Dec 2018 Gaps > 1 mon : none Time Refernce: GMT (hours 00-23) Space-filler Flag :-9999 Units : millimeters Missing Data Flag : 9999 Existing : Yes Operational : Yes Sat. Trans. : Yes Distribution : 1992-2018 Refernce Levl: Vertical Reference Frame is Tide Gauge Zero (TGZ). TGBM Name/Number: 11090 RMI SEAFRAME sensor benchmark (NT Levelling fixtue afer July 2008) TGBM Elevation relative tothe vertical reference: 4.597m Australian Height Datum or 6.535m TGZ Comment : The hourly resdiuals (observations minus predicted tides) show large fluctuations at times within the tidal cycle frequency bands. It is assumed this is due to the inability of the tidal analysis to resolve well all the tidal constituents. The timing of the instrument is assumed of high quality. SPECIAL NOTE TO USERS OF NAT.
