QUALITY ASSESSMENT OF SEA LEVEL DATA by the UH SEA LEVEL CENTER/NATIONAL OCEANOGRAPHIC DATA CENTER JOINT ARCHIVE FOR SEA LEVEL updated: 13 Dec 1999 Station : Belize Latitude: 17 30.0N Country : British Honduras Longitude: 088 11.0W JASL # : 781A Time Meridian: 090W (GMT - 6 hr) GLOSS # : none TOGA #: none NODC #: 71087801 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 : 01 Jan 1964 - 02 Oct 1967 Gaps > 1 mon : 01 Feb 1964 - 01 Mar 1964;31 Mar 1964 - 01 May 1964 01 Jan 1967 - 06 Feb 1967 Time Refernce: GMT (hours 00-23) Space-filler Flag :-9999 Units : millimeters Missing Data Flag : 9999 Existing : No Operational : No Sat. Trans. : No Distribution : 1964-1967 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. Comment : The reference level stability of this series is of good quality. There is good agreement with the nearest station, Puerto Cortes, Honduras.
