Carte biomasse Afrique

This dataset gives estimates of the woody above-ground biomass (AGB) of the savannahs and woodlands of continental Africa and Madagascar at a resolution of 50m x 50m, obtained through a bayesian inversion of an L-band SAR mosaic from ALOS PALSAR (HH and HV polarizations), with the help of 144 reference plots.

AGB is estimated between 0 and 85 Mg.ha-1, and dense forests, flooded forest, mangroves, urban areas and water bodies are masked out using the ESA CCI Land Cover.
