QUALITY ASSESSMENT OF SEA LEVEL DATA by the UH SEA LEVEL CENTER/NATIONAL OCEANOGRAPHIC DATA CENTER JOINT ARCHIVE FOR SEA LEVEL updated: 19 Nov 2019 Station : Barbers Point,HI Latitude: 21 19.2N Country : USA Longitude: 158 07.2W JASL # : 547A Time Meridian: 150W (GMT - 10 hr) GLOSS # : none Originator #: 547 NODC #: 72151801 Contributor : UH Sea Level Center 1000 Pope Rd. MSB 317 Honolulu, Hawaii 96822 Originator : same Original Data: digital Instrmnt Type: 1. 6/2009- radar (RAD) gauge (Vega Vegapuls 62) 2. 6/2009- pressure transducer (PRS) Primary channel used in JASL set: 2009-2018: RAD *short gaps in primary channel filled with other channels as available; see UHSLC for specific dates Digitzd Intvl: 2 min Present Data : Hourly, daily, and monthly values obtained by: Hourly : Hanning filter centered on the hour 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 : 06 Jun 2009 - 31 Dec 2018 Gaps > 1 mon : 01 Nov 2011 - 16 May 2012;17 Jul 2017 - 25 Sep 2017 Time Refernce: GMT (hours 00-23) Space-filler Flag :-9999 Units : millimeters Missing Data Flag : 9999 Existing : yes Operational : yes Sat. Trans. : yes Distribution : 2009-2018 Refernce Levl: Heights are referred to the station tide staff zero, which is linked to land-based benchmarks. This reference zero is unique to this station and is not an official datum (chart, national, etc.) and is not relative to local tidal parameters, such as mean lower low water. See the Originators for benchmark descriptions, maps, and the geodetic levelling history. Comment : The location is on the SW corner of Oahu, Hawaii. Some years have large daily gaps that have been filled. JASL Nov 2019 update replaces 2016- 17 Jul 2017.
