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 : Valparaiso Latitude: 33 01.6S Country : Chile Longitude: 071 37.6W JASL # : 081A Time Meridian: 060W (GMT - 4 hr) GLOSS # : 175 Originator #:0370 NODC #: 53073101 Contributor : Servicio Hidrografico y Oceanografico de la Armada (SHOA) Valparaiso CHILE Originator : SHOA and 1993-2012, in collaboration with UH Sea Level Center University of Hawaii at Manoa Honolulu, HI 96822 Original Data: analog (bub,std); digital (others) Instrmnt Type: 1) standard float/well (std) 1a) Bristol bubbler (8/1982 - 12/1985) 2) Metercraft bubbler (12/1985 - 1999) *primary gauge 12/1985-19/AUG/1997 2b) Metercraft bubbler attached to Handar 540 *primary gauge 01/OCT/1998-08/NOV/1998 After 08/NOV/1998, attached to Handar 555 3) Handar Encoder (12/1985 - 1996) (backup) 4) Aquatrak acoustic gauge (AAG) with Sutron recording platform (1993-08/NOV/1998) then with Handar 555 platform (08/NOV/1998-) *primary gauge 20/AUG/1997-30/SEP/1998 and 09/NOV/1998-AUG2006 5) Druck PTX 1830 Pressure Sensor (2000-) PRS 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. 6) 08/2005-05/2006, 07/2010- radar (RAD) Vega Vegapuls 62 Primary channel used in JASL set (mm/dd/yyyy): 1944-7/1982: std 8/1982-11/08/1998: bub 11/09/1998-08/2006: AAG 08/2006-02/2010: PRS 02/2010-2014: RAD *short gaps in primary channel filled with other channels as available; see UHSLC for specific dates Digitzd Intvl: 1 hour (bub), 15 minutes (enc), 2 min (PTX), 6 min (AAG).

Trans. : Yes Distribution : 1944-2018 Refernce Levl: The originators have related the data to the primary bench mark, BM#2, established in 1941. 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. The mean level from July 1971 - 1978 is suspiciously low. Select gaps in the originators data were replaced by data received via satellite at the UHSLC. Only gaps where the mean difference between the originators and the UHSLC series were constant on either side of the gap were filled. * below indicates gaps filled with Encoder data, # for Bubbler data, $ for AAG, % for PRS. Tsunami signal is evident in the hourly residuals beginning 27 February, 2010 and again in 12-14 March 2011. 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 23Z 2007/10/05 10Z
