Trends of land surface phenology derived from passive microwave and optical remote sensing systems and associated drivers across the dry tropics 1992–2012 [PDF]

, 2019
Changes in vegetation phenology are among the most sensitive biological responses to global change. While land surface phenological changes in the Northern Hemisphere have been extensively studied from the widely used long-term AVHRR (Advanced Very High ...

Ecohydrological Land Reanalysis: Vegetation Water Content and Soil Moisture Data by Land Data Assimilation

Geoscience Data Journal, Volume 12, Issue 4, October 2025.
ECoHydrological Land reanalysis (ECHLA) realises the long‐term spatiotemporally continuous data set of water and vegetation by integrating microwave satellite observations and an ecohydrological model. ABSTRACT The accurate estimation of terrestrial water and vegetation is a grand challenge in hydrometeorology. Many previous studies developed land data

Enhanced Satellite Monitoring of Dryland Vegetation Water Potential Through Multi‐Source Sensor Fusion

Geophysical Research Letters
Drylands are critical in regulating global carbon sequestration, but the resiliency of these semi‐arid shrub, grassland and forest systems is under threat from global warming and intensifying water stress.

A Multimodal Deep Learning Approach for Soil Moisture Downscaling Using Remote Sensing and Weather Data

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Understanding soil moisture (SM) dynamics is crucial for environmental and agricultural applications. While satellite‐based SM products provide extensive coverage, their coarse spatial resolution often fails to capture local SM variability.

Soil moisture and vegetation optical depth retrievals over heterogeneous scenes using LEWIS L-band radiometer

International Journal of Applied Earth Observations and Geoinformation, 2021
The Soil Moisture and Ocean Salinity (SMOS) satellite has been providing global data for more than 11 years. The algorithm to retrieve surface soil moisture (SM) and vegetation optical depth (VOD) from Brightness Temperatures (TB) has constantly evolved ...

Designing of Self‐Dispersing Soft Dendritic Microcleaners for Microplastics Capture and Recovery

Advanced Functional Materials, Volume 35, Issue 34, August 22, 2025.
The capture and recovery of microplastics from open aquatic systems is a complex problem, which necessitates nontrivial solutions. The principles of a comprehensive multistage process based on sustainably sourced microcleaners with hierarchical morphology are demonstrated.

A carbon sink-driven approach to estimate gross primary production from microwave satellite observations [PDF]

, 2019
Global estimation of Gross Primary Production (GPP) - the uptake of atmospheric carbon dioxide by plants through photosynthesis - is commonly based on optical satellite remote sensing data.

Plant Water Storage Optimality Across Hydroclimatic Landscapes

Ecohydrology, Volume 18, Issue 5, July‐August 2025.
ABSTRACT A quantification of the mechanisms underlying plant water use strategies is central to understanding plant stress vulnerability, productivity and subsequent responses to hydroclimatic shifts. To explore such dynamics, we developed a dynamical model for the changes of internal plant water storage (PWS) and soil moisture given a set of coupled ...

L-Band Vegetation optical depth and effective scattering albedo estimation from SMAP [PDF]

, 2017
Over land the vegetation canopy affects the microwave brightness temperature by emission, scattering and attenuation of surface soil emission. Attenuation, as represented by vegetation optical depth (VOD), is a potentially useful ecological indicator ...

Higher Sensitivity of L‐Band Vegetation Optical Depth to Foliage Than Total Aboveground Biomass

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract L‐band vegetation optical depth (VOD) has been widely used to estimate spatiotemporal variations of forest biomass. However, the sensitivity of L‐VOD to different vegetation components, such as foliage and stems, remains poorly understood despite their distinct interannual variations.
