文摘
- •
A Long-term VOD dataset is evaluated against NDVI and in situ biomass observations.
- •
Both VOD and NDVI reflect the spatio-temporal patterns of biomass in West Sahel.
- •
VOD captures variations of woody plant foliage biomass better than NDVI.
- •
VOD and NDVI seasonal metrics differ for optimal long-term monitoring of biomass.
