Abstract
The analysis of sea-level variability along West Africa has been hampered by the limited length and
quality of tide-gauge records. Ghana is the only country along the West African coast with relatively
long sea-level records available.
In this study we aim on characterizing the large-scale climate forcing that drive mean sea-level
variability at and off the coast of Ghana and study its decadal variability and long-term trends in the
observational period.
For this purpose, available sea-level information (referred from tide gauges, satellite altimetry,
gridded reconstructions and ocean model simulations) will be statistically analyzed together with
meteorological data from reanalysis products and climate model simulations. The main large-scale
climate factors driving regional mean sea level at these timescales will be identified and quantified.
