QUALITY ASSESSMENT OF SEA LEVEL DATA by the UH SEA LEVEL CENTER/NATIONAL OCEANOGRAPHIC DATA CENTER JOINT ARCHIVE FOR SEA LEVEL Station : Puerto Armuelles-A Latitude: 08 16.4N Country : Panama Longitude: 082 51.6W JASL # : 304A Time Meridian: 075W (GMT - 5 hr) GLOSS # : none TOGA #: none NODC #: 70088201 Contributor : Instituto Geografico Nacional Apartado 5267 Panama 5, PANAMA (obtained via Scripps Oceanographic Institute) Originator : same Original Data: analog Instrmnt Type: standard mechanical float and well gauge Digitzd Intvl: hourly Present Data : Hourly, daily, and monthly values obtained by: Hourly : spot sampled 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 Jul 1955 - 31 Dec 1968 Gaps > 1 mon : 05 Nov 1960 - 05 Dec 1960;13 Nov 1962 - 01 Feb 1963 01 Apr 1964 - 01 Jun 1964 Time Refernce: GMT (hours 00-23) Space-filler Flag :-9999 Units : millimeters Missing Data Flag : 9999 Existing : Yes Operational : Yes Sat. Trans. : No Distribution : 1955-1968 Refernce Levl: The data have been linked to tide staff zero by the originators. One short obvious shift was adjusted by adding 400 mm to the original data: (18) 28 Jan - (15) 01 Feb 1964. This series is distinguished from 304B because they have not been linked to a common datum. Comment : The daily and monthly means do not show any signs of reference level shifts agree well with the neighboring stations (Balboa, Quepos, and Acapulco). Notable episodic events: 23-25 May 1960: Tsunami from S.C. Chile 28 Mar 1964: Tsunami from Alaska CI MISSING REPLACED GAPS QUESTIONABLE YEAR (%) DATA OR BAD DATA FLUCTUATIONS ---- --- -------------------- --------------- -------------------- 1955 47 none none none 1956 100 none none 240,281 1957 100 none none none 1958 100 none none 362-365 1959 100 none none 1-5,225-227 1960 91 310-340 (00)002-(14)002 276-281 (01)033-(22)033 1961 97 104-106,110-119 none 48,93-97,178,255, 278 1962 80 10-17,83-99,317-365 (22)053-(05)054 137-138 1963 91 1-32 (04)308-(15)308 112,142,172-177 1964 83 92-153 none 193-195 1965 100 none (03)061-(22)061 314-315,342-343 1966 94 1-4,9-10,13-15,75-91 (22)006-(21)007 101-102,257 (08)033-(16)033 (05)034-(17)034 (18)345-(17)346 1967 100 none none 219-226 1968 100 none none 113,133-135,278
