Global Monitoring of the Vegetation Dynamics from the Vegetation Optical Depth (VOD): A Review
Remote Sensing, 2020 Vegetation is a key element in the energy, water and carbon balances over the land surfaces and is strongly impacted by climate change and anthropogenic effects. Remotely sensed observations are commonly used for the monitoring of vegetation dynamics and

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 ...

SMOS-IC: An Alternative SMOS Soil Moisture and Vegetation Optical Depth Product
Remote Sensing, 2017 The main goal of the Soil Moisture and Ocean Salinity (SMOS) mission over land surfaces is the production of global maps of soil moisture (SM) and vegetation optical depth (τ) based on multi-angular brightness temperature (TB) measurements at L-band. The

Estimating Gravimetric Water Content of a Winter Wheat Field from L-Band Vegetation Optical Depth
Remote Sensing, 2019 A considerable amount of water is stored in vegetation, especially in regions with high precipitation rates. Knowledge of the vegetation water status is essential to monitor changes in ecosystem health and to assess the vegetation influence on the water ...

Assessing the sensitivity of multi-frequency passive microwave vegetation optical depth to vegetation properties [PDF]
Biogeosciences, 2023 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 ...
