QUALITY ASSESSMENT OF SEA LEVEL DATA by the UH SEA LEVEL CENTER/NATIONAL OCEANOGRAPHIC DATA CENTER JOINT ARCHIVE FOR SEA LEVEL Updated: 27 Nov 2019 Station : Muscat-B Latitude: 23 37.7N Country : Oman Longitude: 058 33.9E JASL # : 110B Time Meridian: 060E (GMT + 4 hr) GLOSS # : none Originator #: 110 NODC #: 12053801 Contributor : UH Sea Level Center 1000 Pope Rd. MSB 317 Honolulu, Hawaii 96822 Originator : UH Sea Level Center in collaboration with Director of Meteorology CIVAIR SEEB International Airport P. O. Box 204 Muscat, Sultanate of Oman As of the 2019 JASL update, UHSLC no longer maintains this station, though are still receiving the data via satellite and providing to JASL. Original Data: digital Instrmnt Type: 1. 12/2009- radar (RAD) gauge (Vega Vegapuls 62) 2. 12/2009- 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 : three-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 : 10 Dec 2009 - 31 Dec 2018 Gaps > 1 mon : 06 Oct 2011 - 01 Jan 2012 Time Refernce: GMT (hours 00-23) Space-filler Flag :-9999 Units : millimeters Missing Data Flag : 9999 Existing : Yes Operational : Yes Sat. Trans. : No 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. 110B is unique from 110A since it does not have the same reference zero. The benchmarks from 110A were not recovered when 110B was established. Comment : The daily and monthly values do not reveal any obvious reference level shifts or trends. JASL Nov 2019 update replace 2016- 05 Sep 2017. No switch calibration data from 2016 on. However, comparisons with altimeter suggest stable reference level.
