QUALITY ASSESSMENT OF SEA LEVEL DATA by the UH SEA LEVEL CENTER/NATIONAL OCEANOGRAPHIC DATA CENTER JOINT ARCHIVE FOR SEA LEVEL updated: 26 Sep 2019 Station : Antofagasta Latitude: 23 39.2S Country : Chile Longitude: 070 24.3W JASL # : 080A Time Meridian: 060W (GMT - 4 hr) GLOSS # : 174 Originator #:0265 NODC #: 52073001 Contributor : Servicio Hidrografico y Oceanografico de la Armada (SHOA) Casilla 324 Valparaiso CHILE Originator : same Original Data: analog except digital (PTX,RAD) Instrmnt Type: standard mechanical (01/1945 - 02/1987) Metercraft bubbler (03/1987-) Druck PTX 1830 Pressure Sensor (2000-) vented for atmospheric pressure providing a continuous correction for changes in atmospheric pressure (differential pressure transducer). Druck measures the same level as a conventional float/well gauge. Vega Vegapuls 62 radar (07/2010-) Digitzd Intvl: one hour for analog; 2 minutes for PTX,RAD Present Data : Hourly, daily, and monthly values obtained by: Hourly : spot hourly 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 Dec 1945 - 31 Dec 2018 Gaps > 1 mon : 01 Jun 1949 - 01 Jul 1949;01 May 1967 - 01 Jun 1967 01 Dec 1970 - 05 Apr 1971;01 Sep 1977 - 03 Nov 1977 29 Sep 1978 - 01 Jun 1979;01 Oct 1980 - 31 Dec 1980 01 Jan 1982 - 20 Aug 1982;01 Apr 1984 - 01 Jun 1984 09 Nov 1988 - 16 Dec 1988;02 Aug 1993 - 20 Sep 1993 01 Nov 2008 - 08 Aug 2009 Time Refernce: GMT (hours 00-23) Space-filler Flag :-9999 Units : millimeters Missing Data Flag : 9999 Existing : Yes Operational : Yes Sat. Trans. : No Distribution : 1945-2018 Refernce Levl: The originators have related the data to the primary bench mark, BM#8, established in 1945. Comment : The originators re-examined the historic data and applied a thorough calibration and correction. All years in the JASL archive were replaced in January 2004 with the originator's updated series. Tsunami signal is evident in the hourly residuals beginning 27 February, 2010. Residuals are noisy Jan 2010 - 13 Nov 2010. PTX data received by satellite communications at the UHSLC were used to fill gaps in the original SHOA series for the following periods: yyyy/mm/dd hh yyyy/mm/dd hh 2007/10/02 11Z - 2007/10/05 10Z
