How accurately does L band vegetation optical depth predict aboveground biomass?
International Journal of Applied Earth Observations and GeoinformationL-band Vegetation Optical Depth (L-VOD) has emerged as a critical remote sensing proxy for monitoring global aboveground biomass (AGB) dynamics. Persistent methodological ambiguities, including the absence of standardized protocols for deriving AGB from ...
