QUALITY ASSESSMENT OF SEA LEVEL DATA by the UH SEA LEVEL CENTER/NATIONAL OCEANOGRAPHIC DATA CENTER JOINT ARCHIVE FOR SEA LEVEL updated: 01 Nov 2019 Station : Lautoka Latitude: 17 36.3S Country : Fiji Longitude: 177 26.3E JASL # : 402A Time Meridian: 180E (GMT + 12 hr) GLOSS # : none Originator #: ID070004 NODC #: 31177701 Contributor : National Tidal Centre, Bureau of Meteorology PO Box 421 Kent Town SA 5071 South Australia AUSTRALIA Originator : same Original Data: digital Instrmnt Type: Aquatrak acoustic gauge (SEAFRAME) Digitzd Intvl: 6 minute (average of 181 one minute samples) Present Data : Hourly, daily, and monthly values obtained by: Hourly : Cosine-Lanczos filter with cutoff of 120 min. 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 : 24 Oct 1992 - 31 Dec 2018 Gaps > 1 mon : 27 Sep 1995 - 11 Nov 1995 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: All heights have been referred to the station Tide Gauge Zero (TGZ), which is linked to fixed bench marks. Reduced Levels based on Mean Sea Level derived from the Wharf Pillar in the 1992 survey are available. Height of Seaframe Sensor Bench Mark (SSBM) above TGZ is 4.4326m. Comment : High resolution coordinates are: Lat: 17 deg 36 min 19 sec S Lon: 177 deg 26 min 17 sec E The daily and monthly values are reasonable and do not reveal any obvious reference level shifts. Cyclones near Fiji caused the short-lived anomalies of Dec 1992-Jan 1993. SPECIAL NOTE TO USERS OF NAT.
