DACCIWA aims to quantify the influence of human-caused and natural emissions on air quality, clouds and rainfall over southern regions of West Africa and assess their impact on human and ecosystem health and agricultural productivity.
Massive economic and population growth and urbanisation are expected to lead to a tripling of anthropogenic emissions in southern West Africa (SWA) between 2000 and 2030, the impacts of which on human health, ecosystems, food security and the regional climate are largely unknown.
An assessment of these impacts is complicated by:
DACCIWA will also quantify the coupling between aerosols and clouds and identify controls on the formation and persistence of low-level clouds. Further it will identify meteorological controls on precipitation, focusing the transition from stratus to convective clouds and the forcing from weather systems. DACCIWA will quantify the two way cloud and aerosol impacts on the radiation and energy budgets from the cloud scale to the scale of the West African monsoon circulation.
State-of- the-art meteorological, chemistry and air-quality models, satellite retrievals of clouds, precipitation, aerosols and radiation will be assessed in close collaboration with operational centres and research findings will be communicated to policy-makers, scientists, operational centres, students, and general public using a graded communication strategy.
