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.
