Contrasting Responses of Winter Wheat to Waterlogged and Non‐Waterlogged Coal Mining Subsidence Revealed by Integrated DInSAR and UAV Red‐Edge Remote Sensing

Food and Energy Security, Volume 15, Issue 6, November/December 2026.
ABSTRACT This study aimed to clarify the spatiotemporal differences in the growth responses of winter wheat (Triticum aestivum L.) to mining subsidence across different growth stages and hydrological conditions in high‐groundwater‐level Coal–Grain Composite Areas (CGCAs).

Multibaseline Polarimetric SAR Interferometry Coherence Optimization [PDF]

, 2008
This letter analyzes different approaches for polarimetric optimization of multibaseline (MB) interferometric coherences. Two general methods are developed to simultaneously optimize coherences for more than two data sets. The first method provides every

All‐Sky Interferometric Meteor Radar Observations of Zonal Structure and Drifts of Low‐Latitude Ionospheric E Region Irregularities

Earth and Space Science, 2019
All‐sky interferometric meteor radar has been operated worldwide for the measurements of neutral winds in the mesopause region. In this paper, we employ an all‐sky meteor radar and an ionospheric radar, which are situated at Ledong (18.4°N,109°E) and ...

Do Shallow Slip Deficits Reflect Fault Structural Maturity or Modeling Choices? A Comparative Analysis of Tibetan Strike‐Slip Earthquakes

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract InSAR‐constrained finite fault slip models are often used to characterize fault geometries and slip distributions of large continental earthquakes. A common feature of these models is a decrease in slip near the surface, commonly expressed as a percentage shallow slip deficit (SSD).

Acoustic‐Seismic Coupling Signals From Aircraft Reveal Firn‐Ice Transition and Near‐Surface Elastic Structure of Antarctic Ice

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Predicting the response of Antarctic ice to climate change requires detailed knowledge of its shallow structure, but direct measurements are challenging. Traditional seismic surveys are logistically demanding, and surface remote sensing provides limited information about subsurface layers.

Interferometry of ionospheric E-region irregularities based on Kunming VHF radars

Frontiers in Astronomy and Space Sciences
There is a long history of using VHF radar systems to detect ionospheric irregularities based on the theory of coherent scattering. According to previous work, there is a high occurrence of field-aligned irregularities (FAIs) in the ionospheric E-region ...

The Buckland Park MF radar: routine observation scheme and velocity comparisons [PDF]

Annales Geophysicae, 2004
This paper describes the routine observations scheme implemented for the Buckland Park medium frequency (BPMF) radar. These observations are rare among current MF/HF radar observations in that they are made using a relatively narrow transmit polar ...
