QUALITY ASSESSMENT OF SEA LEVEL DATA by the UH SEA LEVEL CENTER/NATIONAL OCEANOGRAPHIC DATA CENTER JOINT ARCHIVE FOR SEA LEVEL updated: 29 Sep 2015 Station : Aden Latitude: 12 47.3N Country : Yemen, P.D.R Longitude: 044 58.5E JASL # : 172A Time Meridian: 045E (GMT + 3 hr) GLOSS # : 003 Originator #: NODC #: 11042401 Contributor : National Oceanography Centre Joseph Proudman Building 6 Brownlow Street Liverpool L3 5DA United Kingdom Originator : Port of Aden Aden, Yemen, P.D.R. Original Data: digital Instrmnt Type: OTT Kalesto radar sensor 2 x OTT ODS4-K pressure sensor (backup) Digitzd Intvl: 1 or 3 min Present Data : Hourly, daily, and monthly values obtained by: Hourly : Data provided to JASL at 15-minute intervals. Spot readings on the hour were made. 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 : 09 Oct 2007 - 31 Dec 2014 Gaps > 1 mon : 14 Jul 2013 - 21 Aug 2013 Time Refernce: GMT (hours 00-23) Space-filler Flag :-9999 Units : millimeters Missing Data Flag : 9999 Existing : Yes Operational : Yes Sat.

Benchmark Description ADEN-BM-CEO Main Benchmark at Chief's Engineers Office ADEN-BM01 Benchmark at Tide Gauge ADEN-BM01-old Old Tide Gauge Benchmark ADEN-BM02 Benchmark at Electrical office ADEN-BM03 Benchmark at Pier (north side) ADEN-BM04 Benchmark in the wall of the Technical Department ADEN-BM05 Benchmark in Christ Church at Ras Morbat Datum Relationships: TGZ = Chart Datum TGZ = 4.134m below ADEN-BM-CEO TGZ = 3.350m below ADEN-BM01 TGZ = 2.803m below ADEN-BM01-old TGZ = 4.066m below ADEN-BM02 TGZ = 3.018m below ADEN-BM03 TGZ = 3.996m below ADEN-BM04 TGZ = 4.318m below ADEN-BM05 Comment : 1) BODC notes: Amplitudes and phases of main tidal constituents have been compared with previously calculated values. Records have been visually inspected for spikes, datum shifts and timing errors. 2) JASL: gaps 24 hour or less were interpolated at the JASL. Daily means agree well with Djibouti suggesting steady reference level. The tide gauge is located at Pilots Pier in the district of Tawihi. The area around the tide gauge hut is used by the Technical Department of the Gulf of Aden Ports Corporation. One-minute data 2015-2016 were received in June 2017. The signal is exceptionally noisy with numerous short gaps. The data are withheld from the research quality set.
