How accurately does L band vegetation optical depth predict aboveground biomass?
L-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 ...

Assessing the sensitivity of multi-frequency passive microwave vegetation optical depth to vegetation properties [PDF]
Vegetation attenuates the microwave emission from the land surface. The strength of this attenuation is quantified in models in terms of the parameter vegetation optical depth (VOD) and is influenced by the vegetation mass, structure, water content, and ...

Monitoring post-fire recovery of various vegetation biomes using multi-wavelength satellite remote sensing [PDF]
Anthropogenic climate change is now considered to be one of the main factors causing an increase in both the frequency and severity of wildfires. These fires are prone to release substantial quantities of CO2 into the atmosphere and to endanger natural ...
