Mixing Patterns of River Deltas Obtained From Remotely Sensed Rouse Number

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 12, December 2025.
Abstract River deltas have complex vertical sediment dynamics within their distributary channel networks. These dynamics suggest that remotely sensed suspended sediment concentration (SSC), which captures surface conditions, is insufficient for investigating delta mixing.

Imaging Spectroscopy for Enhancing Regional Coastal Wetland Extent Monitoring

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 10, October 2025.
Abstract Coastal wetland habitats contribute to important ecosystem services, including improved water quality, carbon sequestration, and flood mitigation, but they are difficult to be monitored in situ due to their inaccessibility. This research aims to explore the potential and limitation of monitoring coastal wetland habitats in the Greater Cape ...

Space-based remote imaging spectroscopy of the Aliso Canyon CH_4 superemitter [PDF]

, 2016
The Aliso Canyon gas storage facility near Porter Ranch, California, produced a large accidental CH_4 release from October 2015 to February 2016. The Hyperion imaging spectrometer on board the EO-1 satellite successfully detected this event, achieving ...

Using imaging spectroscopy and elevation in machine learning to estimate soil salinity in intermittently tidal wetlands

Ecosphere, Volume 16, Issue 8, August 2025.
Abstract Coastal soil salinization patterns are changing due to drought, sea level rise (SLR), and changing freshwater inflow. These changes are expected to impact coastal wetland plant health and ecosystem function, such as changes to biomass and productivity.

Neural network for aerosol retrieval from hyperspectral imagery [PDF]

Atmospheric Measurement Techniques, 2019
We retrieve aerosol optical thickness (AOT) independently for brown carbon, dust and sulfate from hyperspectral image data. The model, a neural network, is trained on atmospheric radiative transfer calculations from MODTRAN 6.0 with varying aerosol ...

High spatial resolution imaging of methane and other trace gases with the airborne Hyperspectral Thermal Emission Spectrometer (HyTES) [PDF]

, 2016
Currently large uncertainties exist associated with the attribution and quantification of fugitive emissions of criteria pollutants and greenhouse gases such as methane across large regions and key economic sectors.

Can Imaging Spectroscopy Divulge the Process Mechanism of Mineralization? Inferences from the Talc Mineralization, Jahazpur, India

Remote Sensing, 2023
Talc deposits of Jahazpur, Rajasthan, hosted by dolomite, are one of the largest high-quality talc deposits in India. In the present study, we use AVIRIS-NG datasets to study the link between the spatial pattern of talc mineralization, associated ...

Controlling Factors on Water and Sediment Partitioning at Deltaic Bifurcations

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 7, July 2025.
Abstract Bifurcations in river‐dominated deltas are the main actors in the routing of water and sediments throughout the fluvial network. In spite of previous acknowledgments of their importance, we still lack a comprehensive framework on how bifurcation geometry affects water and sediment partitioning.

Performance of Airborne Imaging Spectrometers for Carbon Dioxide Detection and Emission Quantification

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 7, 16 April 2025.
Abstract Carbon dioxide (CO2) emissions from strong point sources account for a significant proportion of the global greenhouse gas emissions, and their associated uncertainties in bottom‐up estimates remain substantial. Imaging spectrometers provide a capability to monitor large point source CO2 emissions and help reduce the uncertainties.
