Demonstration of Spaceborne Multi-static SAR Tomography and Forest Height Estimation

Leida xuebao
Synthetic Aperture Radar Tomography (TomoSAR), by virtue of its three-dimensional (3D) resolution capability, can be used to study the 3D structure of semitransparent targets, such as forests, icebergs, and snowpacks.

Time‐resolved XPCS analysis across broad time‐scales using multi‐tau two‐time correlations

Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 698-707, May 2026.
A scalable multi‐tau two‐time correlation framework enables efficient, time‐resolved XPCS analysis of long duration high‐frame‐rate modern synchrotron data while preserving sensitivity to non‐stationary dynamics.We present a multi‐tau two‐time correlation (MT‐2TC) analysis for X‐ray photon correlation spectroscopy that enables efficient analysis of ...

ENSO Recharge Oscillator Theory Integrating the Southward Wind Shift

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The El Niño–Southern Oscillation (ENSO) is one of the most‐well understood climate phenomena, and the Recharge Oscillator (RO) theory is widely used to conceptualize its physics in observations and models. ENSO‐associated equatorial zonal wind anomalies shift southward in boreal winter, contributing to ENSO termination.

Inversion of Boreal Forest Height Using the CRITIC Weighted Least Squares Three-Stage Temporal Decorrelation Iterative Algorithm

Remote Sensing
The inversion of forest height using the RVoG (Random Volume over Ground) model is susceptible to overestimation or underestimation due to three error sources, propagating inaccuracies to the estimated forest height. Furthermore, variations in the height

Comparison of L-band and X-band differential interferometric synthetic aperture radar for mine subsidence monitoring in central Utah

International Journal of Mining Science and Technology, 2017
Differential interferometric synthetic aperture radar (DInSAR), a satellite-based remote sensing technique, has potential application for measuring mine subsidence on a regional scale with high spatial and temporal resolutions.

Atmospheric Adjustments to In Situ Cirrus Formation in Ice Supersaturated Regions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract High‐level ice clouds exert a net warming on the climate system because their greenhouse effect outweighs their albedo effect. Focusing on in‐situ cirrus, their formation involves the conversion of upper‐tropospheric water vapor into ice crystals.

StaMPS Improvement for Deformation Analysis in Mountainous Regions: Implications for the Damavand Volcano and Mosha Fault in Alborz

Remote Sensing, 2015
Interferometric Synthetic Aperture Radar (InSAR) capability to detect slow deformation over terrain areas is limited by temporal decorrelation, geometric decorrelation and atmospheric artefacts.

Stochastic dynamics of active swimmers in linear flows

, 2014
Most classical work on the hydrodynamics of low-Reynolds-number swimming addresses deterministic locomotion in quiescent environments. Thermal fluctuations in fluids are known to lead to a Brownian loss of the swimming direction.
