Assessment of the Impact of Spatial Heterogeneity on Microwave Satellite Soil Moisture Periodic Error [PDF]

An accurate temporal and spatial characterization of errors is required for the efficient processing, evaluation, and assimilation of remotely-sensed surface soil moisture retrievals.

Estimating Vegetation Optical Depth With Mobile GNSS Transmissiometry in Temperate Forests During SMAPVEX22

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
This study investigates the potential of mobile global navigation satellite system (GNSS) transmissometry (GNSS-T) measurements for estimating vegetation optical depth (VOD) in temperate forests, focusing on the Soil Moisture Active Passive (SMAP ...

Vegetation optical depth as a key predictor for fire risk escalation

Ecological Informatics
Excluding direct consideration of vegetation dynamics reduces the accuracy in fire risk estimation. Satellite retrievals of vegetation dynamics can enhance the fire risk prediction when used as indicators of fuel water status and fuel load.

Estimating canopy interception water storage with GNSS-transmissometry [PDF]

Storage of interception water in the canopy (S c ) heavily affects measurements of vegetation optical depth (VOD) from rain, dew and fog, impeding the direct retrieval of tree physiological parameters such as biomass and plant water content.

Emerging Methods to Validate Remotely Sensed Vegetation Water Content

Geophysical Research Letters
Satellite‐retrieved vegetation optical depth (VOD) has provided extensive insights into global plant function (such as, carbon stocks, water stress, crop yields) because of VOD's ability to monitor plant water stress and biomass at near daily temporal ...

Intraseasonal variability of vegetation water content in India driven by monsoon hydrometeorology

Environmental Research Letters
Understanding how Indian vegetation during the summer monsoon (June–September) responds to intraseasonal variability, with hydrometeorological stressors like vapor pressure deficit (VPD) and soil moisture (SM), is crucial and yet it is not well-explored.

Analyzing satellite and airborne Ka-band passive microwave observations over land for temperature and vegetation monitoring

Frontiers in Remote Sensing
Passive microwave observations at Ka-band (36‐37 GHz) have been widely available for decades, but their full potential for land applications has been hardly exploited. This study analyzed Ka‐band observations at different spatial scales.

SMAP Validation Experiment 2019–2022 (SMAPVEX19–22): Field Campaign to Improve Soil Moisture and Vegetation Optical Depth Retrievals in Temperate Forests

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Satellite-based retrieval of forest soil moisture (SM) and vegetation optical depth (VOD) are two long-standing unresolved issues hindering advances in hydrology, ecology, and Earth system science. A key obstacle is the lack of adequate reference data in
