Global Monitoring of the Vegetation Dynamics from the Vegetation Optical Depth (VOD): A Review [PDF]

open access: yesRemote 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?

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
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 ...

Challenges and Limitations in Comparing Satellite Microwave Vegetation Optical Depth (VOD) Against in-Situ Tree Hydraulics in the Canadian Boreal Forest

open access: yesCanadian Journal of Remote Sensing
Microwave remote sensing can be used to estimate vegetation optical depth (VOD), a measure of the attenuation of microwave radiation by vegetation. VOD is tightly linked to vegetation properties such as water content and above-ground biomass.

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

open access: yesBiogeosciences, 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 ...

Monitoring post-fire recovery of various vegetation biomes using multi-wavelength satellite remote sensing [PDF]

open access: yesBiogeosciences, 2022
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 ...
