African Monsoon Region

Impact of Aerosols on Shortwave Flux Retrieval
The goal of the AMMA program is to improve understanding of the West African monsoon (WAM) and the factors that determine its variability on daily to inter-annual timescales. Radiative fluxes are needed for addressing the regional-scale processes of the WAM, where land-surface feedbacks are important. The AMMA region is frequented by dust outbreaks over Africa. It is important to incorporate the effects of dust on the radiative fluxes that reach the surface and control the hydrological cycle.
