Observations from spaceborne radar contain considerable information about vegetation
dynamics. The ability to extract this information could lead to improved soil moisture …

The satellite based passive (radiometer) and active (radar) microwave sensors enhanced
our ability to retrieve soil moisture at global scales. It has been almost four decades since …

Abstract Climate Data Records of soil moisture are fundamental for improving our
understanding of long-term dynamics in the coupled water, energy, and carbon cycles over …

A frequently expressed viewpoint across the Earth science community is that global soil
moisture estimates from satellite L‐band (1.4 GHz) measurements represent moisture only …

Backscatter measured by scatterometers and Synthetic Aperture Radars is sensitive to the
dielectric properties of the soil and normally increases with increasing soil moisture content …

The presence of surface water on the canopy affects radar backscatter. However, its
influence on the relationship between radar backscatter and crop biophysical parameters …

Active microwave measurements have the potential to estimate vegetation optical depth
(VOD), an indicator related to vegetation water content and biomass. The Advanced …

This work describes the first global scale assessment of a Global Navigation Satellite
Systems Reflectometry (GNSS-R) experiment performed on-board the Soil Moisture Active …

At the global scale, the uptake of atmospheric carbon dioxide by terrestrial ecosystems
through photosynthesis is commonly estimated through vegetation indices or biophysical …

The main objective of this study is to analyze the potential use of L-band radar data for the
estimation of soil moisture over tropical agricultural areas under dense vegetation cover …
