Description
Summary:The picture of continent areas that meteorological satellites provide daily is interpreted in terms of chlorophyll activity thanks to an ecological model adapted to global studies. This model simulates the monthly phenological rhythm of the vast and complex vegetation systems of the African continent; results are shown as digitized maps. The paper aims to provide a better understanding and interpretation of satellite measurements. Partial validations through correlations between simulated maps and satellite images can ease the monitoring of the intertropical belt and lead to greater understanding of the global ecological changes that are taking place as a result of growing human impact.
