QUALITY ASSESSMENT OF SEA LEVEL DATA by the UH SEA LEVEL CENTER/NATIONAL OCEANOGRAPHIC DATA CENTER JOINT ARCHIVE FOR SEA LEVEL updated: 25 Sep 2019 Station : San Felix Latitude: 26 17.5S Country : Chile Longitude: 080 06.5W JASL # : 035A Time Meridian: 060W (GMT - 4 hr) GLOSS # : 177 Originator #:0285 NODC #: 52086001 Contributor : Servicio Hidrografico y Oceanografico de la Armada (SHOA) Casilla 324 Valparaiso CHILE Originator : same Original Data: analog and digital (PTX) Instrmnt Type: Metercraft bubbler gauge 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. 3) Vega Vegapuls 62 radar (RAD) (04/2011-) Digitzd Intvl: one hour (Bub); 2 minutes (PTX) 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 Nov 1987 - 31 Dec 2018 Gaps > 1 mon : 24 May 1994 - 14 Sep 1994;28 Sep 1995 - 05 Oct 1996 06 Sep 1997 - 01 Nov 1997;01 Feb 1998 - 21 Jun 1998 28 Feb 1999 - 09 Apr 1999;01 Dec 1999 - 01 Jan 2000 01 Jul 2000 - 01 Sep 2000;12 May 2002 - 14 Jun 2002 26 Sep 2002 - 28 Dec 2002;11 Feb 2006 - 03 Jul 2006 07 Feb 2007 - 15 Mar 2007;01 Jan 2012 - 23 Apr 2012 Time Refernce: GMT (hours 00-23) Space-filler Flag :-9999 Units : millimeters Missing Data Flag : 9999 Existing : Yes Operational : Yes Sat. Trans. : Yes Distribution : 1987-2018 Refernce Levl: The originators have related the data to the primary bench mark, BM#03, established in 1987. Comment : The originators re-examined the historic data and applied a thorough calibration and correction for January 1989 onward. These years in the JASL archive were replaced in March 2004 with the originator's updated series. Comparison with AVISO altimeter suggests better level stability 2010 onward. Tsunami signal is evident in the hourly residuals beginning 27 February, 2010. BUB or PTX data received by satellite 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 12Z 2007/10/05 11Z 2007/12/21
