Toward Constraining Ocean Estimates in Ice‐Covered Regions Using Sea Level Altimetry Data
Earth and Space Science, Volume 13, Issue 5, May 2026.Abstract Estimates of ice‐covered oceans are difficult to constrain using in situ observations, particularly if one needs broad spatiotemporal coverage of subsurface properties. Here we explore the value of sea level (ζ $\zeta $) data from the laser altimeter on ICESat‐2 and multi‐mission radar altimeter products distributed by the Archiving ...

Application of ALOS and Envisat Data in Improving Multi-Temporal InSAR Methods for Monitoring Damavand Volcano and Landslide Deformation in the Center of Alborz Mountains, North Iran [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013 InSAR capacity to detect slow deformation over terrain areas is limited by temporal and geometric decorrelations. Multitemporal InSAR techniques involving Persistent Scatterer (Ps-InSAR) and Small Baseline (SBAS) are recently developed to compensate the ...

Adaptive Temporal Decorrelation of State Estimates
2024 27th International Conference on Information Fusion (FUSION)Many commercial and defense applications involve multisensor, multitarget tracking, requiring the fusion of information from a set of sensors. An interesting use case occurs when data available at a central node (due to geometric diversity or retrodiction) allows for the tailoring of state estimation for a target. For instance, if a target is initially

Temporal decorrelation of collective oscillations in neural networks with local inhibition and long-range excitation [PDF]
, 2007 We consider two neuronal networks coupled by long-range excitatory interactions. Oscillations in the gamma frequency band are generated within each network by local inhibition.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract This study evaluates the performance of ALOS‐2 ScanSAR time series for resolving tectonic, volcanic, hydrologic, and geomorphic deformation across Northern California. Beginning in 2021, ALOS‐2 acquired ScanSAR data with a 14‐day repeat interval over the region, providing the closest available analog to the recently launched NISAR mission. The

Impacts of Temporal-Spatial Variant Background Ionosphere on Repeat-Track GEO D-InSAR System
Remote Sensing, 2016 An L band geosynchronous synthetic aperture radar (GEO SAR) differential interferometry system (D-InSAR) will be obviously impacted by the background ionosphere, which will give rise to relative image shifts and decorrelations of the SAR interferometry ...

Two-Particle Dispersion in Model Velocity Fields
, 1999 We consider two-particle dispersion in a velocity field, where the relative two-point velocity scales according to $v^{2}(r)\propto r^{\alpha}$ and the corresponding correlation time scales as $\tau (r)\propto r^{\beta}$, and fix $\alpha =2/3$, as ...
