African Center of Meteorological Applications for Development (ACMAD)The fAPAR Anomaly dataset maps deviations in vegetation health and photosynthetic activity across Africa. fAPAR measures the proportion of solar radiation absorbed by plants for photosynthesis, making it a robust biophysical indicator of vegetation status. The anomaly product highlights areas where vegetation activity is significantly below or above the long-term average, serving as a primary proxy for agricultural production and biomass availability. Unlike simple greenness indices (like NDVI), fAPAR is physically related to the energy and mass exchange processes of the canopy. Negative anomalies in this dataset are strong indicators of vegetation stress caused by drought, pests, or disease, making it a critical input for yield forecasting and food security analysis.acmad-fapar-anomalyHumanitarian Data ExchangePublicAfrica - Fraction of Absorbed Photosynthetically Active Radiation (fAPAR) AnomalyDatasetsAngolaBurundiBeninBurkina FasoBotswanaCentral African RepublicCôte d'IvoireCameroonDemocratic Republic of the CongoCongoComorosCabo VerdeDjiboutiAlgeriaEgyptEritreaWestern SaharaEthiopiaGabonGhanaGuineaGambiaGuinea-BissauEquatorial GuineaKenyaLiberiaLibyaLesothoMoroccoMadagascarMaliMozambiqueMauritaniaMauritiusMalawiNamibiaNigerNigeriaRwandaSudanSenegalSierra LeoneSomaliaSouth SudanSao Tome and PrincipeEswatiniSeychellesChadTogoTunisiaUnited Republic of TanzaniaUgandaSouth AfricaZambiaZimbabwe2012-01-01 to 2026-03-31
