Response of costal upwelling to stratospheric geoengineering in the Eastern Gulf of Guinea

Project summary
Dr Casimir Da-Allada and his team extends previous research on Stratospheric Aerosol Geoengineering (SAG) in the Northern Gulf of Guinea to the Eastern Gulf of Guinea (EGoG), focusing on the Angola-Namibia upwelling system, a key region for climate and fisheries. Using Geoengineering Large Ensemble (GLENS) simulations, the study will assess how SAG and climate change affect sea surface temperature (SST) variability and the underlying physical processes. Model outputs will be validated with observational and oceanographic data, and changes will be analysed through heat budget diagnostics and statistical testing. By comparing future climate scenarios with and without SAG, the project aims to determine whether geoengineering could mitigate warming impacts in this region. The findings will enhance understanding of SAGs regional effects, inform climate risk management, and strengthen local capacity and leadership in climate geoengineering research in West Africa.
