Expanding the Spatial Reach and Human Impacts of Critical Zone Science

open access: yesEarth's Future, Volume 12, Issue 3, March 2024.
Abstract Two major barriers hinder the holistic understanding of subsurface critical zone (CZ) evolution and its impacts: (a) an inability to measure, define, and share information and (b) a societal structure that inhibits inclusivity and creativity. In contrast to the aboveground portion of the CZ, which is visible and measurable, the bottom boundary

The European Space Agency BIOMASS mission: Measuring forest above-ground biomass from space [PDF]

open access: yes, 2019
The primary objective of the European Space Agency's 7th Earth Explorer mission, BIOMASS, is to determine the worldwide distribution of forest above-ground biomass (AGB) in order to reduce the major uncertainties in calculations of carbon stocks and ...

Pearl Millet Crop Biophysical Parameter Retrieval From Space Borne Polarimetric SAR Data Using Machine Learning

open access: yesEarth and Space Science, Volume 11, Issue 1, January 2024.
Abstract The potential of single date fully Polarimetric RADARSAT‐2 data in retrieving crop biophysical parameters using Machine Learning techniques was investigated. Various polarimetric parameters along with coherent and incoherent decomposition techniques were assessed for its sensitivity toward crop parameters like Wet and Dry Biomass, Crop Height,

A MTInSAR‐Based Early Warning System to Appraise Deformations in Simply Supported Concrete Girder Bridges

open access: yesStructural Control and Health Monitoring, Volume 2024, Issue 1, 2024.
This paper presents an early warning system to investigate deformations in simply supported concrete girder bridges over time, using the information content provided by satellite data, integrated with other available sources. The safety of the existing bridges is a priority for transportation management companies, which should carry out continuous and ...

Estimating mangrove canopy height and above-ground biomass in the Everglades National Park with airborne LiDAR and TanDEM-X data [PDF]

open access: yes, 2017
Mangrove forests are important natural ecosystems due to their ability to capture and store large amounts of carbon. Forest structural parameters, such as canopy height and above-ground biomass (AGB), provide a good measure for monitoring temporal ...

Addressing Forest Change by means of Pol-InSAR Measurements at L- and P-band [PDF]

open access: yes, 2023
By coherently combining interferometric SAR acquisitions at different polarization states, Polarimetric SAR Interferometry (Pol-InSAR) [1] allows to locate in height different scattering mechanisms present in the resolution cell. Together with the use of

Assessment of Paddy Rice Height: Sequential Inversion of Coherent and Incoherent Model

open access: yes, 2018
This paper investigates the evolution of canopy height of rice fields for a complete growth cycle. For this purpose, copolar interferometric Synthetic Aperture Radar (Pol-InSAR) time series data were acquired during the large across-track baseline (>1 km)

4D Characterization of Short- and Long-term Height-varying Decorrelated Forest SAR Backscattering [PDF]

open access: yes, 2015
Pol-InSAR and 3D multibaseline SAR Tomography (Tomo-SAR) can extract rich information on complex scenarios with multiple scatterers mapped in the SAR cell, in particular for forest remote sensing. However, forest scenarios are characterized by a temporal
