Ultra Wide Swath Imaging With Multi-Channel SAR Systems [PDF]

, 2008
Multi-channel radar systems allow for overcoming the inherent limitation of conventional synthetic aperture radar (SAR). An example is the combination of digital beamforming on receive in elevation with multi-aperture SAR signal reconstruction in azimuth

Deep Learning‐Based MultiSource Satellite Data Fusion and Downscaling for Tropical Cyclone Wind Fields

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract High‐resolution observations of ocean surface wind (OSW) are crucial for analyzing and forecasting tropical cyclones; however, current data are insufficient. While data sets such as the Cross‐Calibrated Multiplatform (CCMP) and ERA5 provide gap‐free wind fields, their 25 km resolution and tendency to underestimate cyclone wind speeds limit ...

Analysis of synthetic aperture radar imagery [PDF]

The author has identified the following significant results. Average radar response for L-band like polarized system appeared to be related to the watershed runoff coefficients when the viewing angle was approximately 42 deg off nadir.

Physically Guided GAN‐Based Super Resolution of Buoy Observations for Internal Solitary Waves

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Accurate monitoring of internal solitary waves (ISWs) is crucial for understanding their influence on ocean mixing and energy transfer. Satellite observations offer a powerful tool for large‐scale ISW monitoring, but they mainly detect surface signatures and thus require nearby in situ measurements for validation and amplitude estimation ...

Self‐Supervised Learning Based Clustering Workflow for Exploring Seismological Data From Dense Networks

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract A key challenge in environmental seismology is processing seismic data to study source physics, natural and human‐induced forcings, and geological structures such as landslides, glaciers, and volcanoes. Seismic arrays with dozens of stations have expanded data set sizes, and this, combined with signal complexity and high noise levels, makes it

ORCHIDEE‐MAN: Incorporating Mangrove Processes in the Global Vegetation Model of ORCHIDEE

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 12, December 2025.
Abstract The mangrove ecosystem is characterized by high carbon sequestration rates and plays a crucial role for the exchange of carbon between land and ocean. Understanding the carbon dynamics of mangroves under climate change and human disturbances is therefore essential for quantifying their contributions to global carbon cycle.
