Dr. Rebecca Berkoh-Oforiwaa

Rebecca Berkoh-Oforiwaa uses observational, Satellite Altimetry and sea-level reconstructions datasets to understand how and how sea level has changed along the Gulf of Guinea from the early twentieth century to the present.
Rebecca received her PhD in Atmospheric Physics from the University of Ghana, where she investigated the influence of large-scale ocean-atmosphere interactions—including the El Niño–Southern Oscillation, the North Atlantic Oscillation, and the Indian Ocean Dipole—on rainfall variability across West Africa. Her doctoral research combined reanalysis datasets, precipitation observations, and machine learning methods such as Self-Organizing Maps to examine the seasonal and extreme rainfall responses to oceanic and atmospheric drivers.
As a postdoctoral researcher, Rebecca is focused on using reconstructed sea-level datasets to explore long-term trends, variability, and the physical drivers of sea-level change along the West African coast. She compares reconstructed sea level with tide gauge observations and satellite altimetry, and conducts attribution studies to better understand regional drivers of change. Her work contributes to efforts aimed at improving sea-level projections and supporting coastal adaptation planning in cities such as Accra, Lagos, and Abidjan.
