QUALITY ASSESSMENT OF SEA LEVEL DATA by the UH SEA LEVEL CENTER/NATIONAL OCEANOGRAPHIC DATA CENTER JOINT ARCHIVE FOR SEA LEVEL updated: 03 Nov 2000 Station : Puerto Cortes-A Latitude: 15 50.0N Country : Honduras Longitude: 087 57.0W JASL # : 780A Time Meridian: 090W (GMT - 6 hr) GLOSS # : none TOGA #: none NODC #: 71085701 Contributor : National Ocean Service (NOS) National Ocean. and Atmos. Administration (NOAA) N/OES22 SSMC4, STATION 7109 1305 East West Highway Silver Spring, MD. 20910-3233 Originator : US Coastal Geodetic Survey Original Data: analog Instrmnt Type: standard float and well gauge Digitzd Intvl: hourly Present Data : Hourly, daily, and monthly values obtained by: Hourly : original digitized interval was 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 : 05 Feb 1948 - 31 Dec 1968 Gaps > 1 mon : none Time Refernce: GMT (hours 00-23) Space-filler Flag :-9999 Units : millimeters Missing Data Flag : 9999 Existing : No Operational : No Sat. Trans. : No Distribution : 1948-1968 Refernce Levl: The data have been linked to tide staff zero by the contributors. Information on geodetic surveys of benchmarks can be obtained from the originators. The hourly data were key entered at the Univ. of Hawaii. Tide staff readings were provided and analysed, but no corrections were applied. It appears that the paper tables of hourly values had received the adjustments from the tide staff readings. In comparison with holdings of the PSMSL, the long-term mean agrees well with only some short-term differences on the order of 1 inch in 1950 and 1952-54. Comment : Differences of monthly means with Puerto Castilla and Belize, British Honduras show reasonable agreement.
