QUALITY ASSESSMENT OF SEA LEVEL DATA by the UH SEA LEVEL CENTER/NATIONAL OCEANOGRAPHIC DATA CENTER JOINT ARCHIVE FOR SEA LEVEL updated: 14 Nov 2019 Station : Palmeira,Cape Verde Latitude: 16 45.3N Country : Portugal Longitude: 022 59.0W JASL # : 235A Time Meridian: 015W (GMT - 1 hr) GLOSS # : 329 Originator #:235 NODC #: 71026201 Contributor : UH Sea Level Center 1000 Pope Rd. MSB 317 Honolulu, Hawaii 96822 Originator : Dept. of Oceanography University of Hawaii 1000 Pope Rd. MSB 317 Honolulu, Hawaii 96822 Original Data: digital Instrmnt Type: 1) Aquatrak acoustic gauge, Sutron 9000 DCP (primary 2000-2/2007) (ECS) 2) radar (RAD) (Vega Vegapuls 62) 3) pressure transducer (PRS) primary: ECS 2000-2/2007 RAD 10/2007 - Digitzd Intvl: 6 min (ECS), 3 min (RAD), 2 min (PRS) 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 : 12 Mar 2000 - 31 Dec 2018 Gaps > 1 mon : 05 Jan 2001 - 27 May 2001;13 Oct 2001 - 20 Nov 2001 23 Feb 2007 - 13 Oct 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 : 2000-2018 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 : New site established on the island of Sal replaces the site at Praia, Cape Verde. Daily values agree well with AVISO altimeter. JASL Nov 2019 update replaces 2016- 05 Sep 2017.
