QUALITY ASSESSMENT OF SEA LEVEL DATA by the UH SEA LEVEL CENTER/NATIONAL OCEANOGRAPHIC DATA CENTER JOINT ARCHIVE FOR SEA LEVEL Updated: 08 Nov 2019 Station : Prigi Latitude: 08 16.8S Country : Indonesia Longitude: 111 43.8E JASL # : 125A Time Meridian: 105E (GMT + 7 hr) GLOSS # : none Originator #: 125 NODC #: 30118101 Contributor : University of Hawaii Sea Level Center (UHSLC) 1000 Pope Rd. MSB 317 Honolulu, HI 96822 Originator : UHSLC in collaboration with BAKOSURTANAL J1. Raya Jakarta Bogar Km 46 P. O. Box 46 Cibinong, Indonesia Original Data: digital Instrmnt Type: 1) radar (RAD) gauge (Vega Vegapuls 62) 2) Handar Encoder 436-A (ENC), float/well 3) pressure transducer (PRS) Primary channel used in JASL set: 2007-11/2011: RAD 11/2011-03/2012: ENC 03/2012-: RAD *short gaps in primary channel filled with other channels as available; see UHSLC for specific dates Digitzd Intvl: 3 min (RAD); 2 min (PRS); 15 min (ENC) Present Data : Hourly, daily, and monthly values obtained by: Hourly : 3-point 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 : 25 Feb 2007 - 31 Dec 2018 Gaps > 1 mon : 21 Apr 2007 - 14 Jul 2007 Time Refernce: GMT (hours 00-23) Space-filler Flag :-9999 Units : millimeters Missing Data Flag : 9999 Existing : Yes Operational : Yes Sat. Trans. : Yes Distribution : 2007-2018 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 data are of good quality. Numerous short gaps daily during 24 Nov 2010 - 15 Jan 2011 and 2017. JASL Nov 2019 update replaces 2016- 04 Sep 2017.
