Review of GNSS-R Technology for Soil Moisture Inversion

open access: yesRemote Sensing
Soil moisture (SM) is an important parameter in water cycle research. Rapid and accurate monitoring of SM is critical for hydrological and agricultural applications, such as flood detection and drought characterization.

Soil Moisture Content from GNSS Reflectometry Using Dielectric Permittivity from Fresnel Reflection Coefficients

open access: yesRemote Sensing, 2020
Global Navigation Satellite Systems-Reflectometry (GNSS-R) has shown unprecedented advantages to sense Soil Moisture Content (SMC) with high spatial and temporal coverage, low cost, and under all-weather conditions.

Similar locomotor patterns across Quarter Horse disciplines inform lameness assessment

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Lineage‐based selection is central to the Quarter Horse industry and is often justified by the assumption that morphology determines locomotor function. However, objective evidence linking static conformation to discipline‐specific locomotor behaviour under standardised conditions remains limited.

Heel movement and foot biomechanics in aluminium nail‐on and indirect glue‐on fabric cuff shoes in horses

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Heel movement is critical to shock absorption and vascular perfusion of the equine digit. Conventional horseshoeing techniques are suspected to restrict natural hoof deformation, affecting hoof biomechanics. Several studies have explored the effects of shoeing on hoof function, though many have been limited to artificial conditions,

UAV-Based GNSS-R for Water Detection as a Support to Flood Monitoring Operations: A Feasibility Study

open access: yesApplied Sciences, 2019
Signals from global navigation satellite systems (GNSS) can be utilized as signals of opportunity in remote sensing applications. Geophysical properties of the earth surface can be detected and monitored by processing the back-scattered GNSS signals from

Analysis of Spaceborne GNSS-R Delay-Doppler Tracking

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2014
For spaceborne Global Navigation Satellite System-Reflectometry (GNSS-R), the delay and Doppler frequency conditions dynamically change, so the compensation of the delay and Doppler errors using tracking is important to the altimetric and scatterometric performances.

Retracking considerations in spaceborne GNSS-R altimetry

open access: yes, 2012
The European Space Agency Passive Reflectometry and Interferometry System In-orbit Demonstrator (IoD) aims to perform mesoscale altimetric observations by measuring the Global Navigation Satellite System (GNSS) opportunity signals reflected over the ...

New constraints on the postglacial evolution of Lago Maggiore, Northern Italy

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Lago Maggiore is situated in an overdeepened valley reach at the southern margin of the European Alps, and its thick sediment infill allows the reconstruction of the postglacial valley and lake evolution. We study here the sedimentary succession in the lower Ossola Valley, which is infilled by ~500 m of deposits. In a marginal position, a core

Late Quaternary lake filling and drying in northern Australia's largest freshwater lake

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Lake Woods, Jurrkulu, is northern Australia's largest freshwater lake filled today in strong Indo–Australian summer monsoons (IASM) to maximum depths of ~5 m. On the western margins of the lake, two large arcuate ridges occur 20 to 40 m above the lake floor and inset within these are other mid‐elevation lake deposits, such as depositional ...
