Sea Level Monthly

Name: Ghana Sea Level Monthly
Creator: Permanent Service for Mean Sea Level

Monthly mean sea level measured at Ghana's two tide gauges — Takoradi from 1929 to August 2012 and Tema from 1963 to September 1982 — in millimetres, with the number of days missing from each month and the quality flag the record carries. Heights are on each station's own Revised Local Reference datum, set roughly seven metres below mean sea level so values stay positive: the trend at a station is meaningful, a comparison of absolute heights between stations is not. Both are closed records: no quality-controlled Ghanaian tide-gauge data after 2012 is published under terms that allow reuse (the IOC's raw near-real-time feed from the gauges forbids commercial use). Sourced from the Permanent Service for Mean Sea Level, freely available with acknowledgement. 1027 records.
