Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 1, March 2025.Abstract Complex nonlinear relationships exist between the permafrost thermal state, active layer thickness, and terrestrial carbon cycle dynamics. In Arctic and boreal Alaska, significant uncertainties characterize the spatiotemporal rate and magnitude of permafrost degradation and the permafrost carbon feedback, with increasing recognition of the ...

Astronomische Nachrichten, Volume 346, Issue 1, January 2025.ABSTRACT Observations show that the x‐ray emission of the accreting weakly magnetized neutron stars (WMNSs) is polarized. In this article, we summarize the analytical models for the polarized emission of various components of the WMNSs. We introduce a missing theoretical model, where we assume the emission comes from the spreading layer, the extension ...

Modelling real‐world effects in near‐field SAR collections for compressive sensing
IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.This paper develops previously published work on using compressive sensing techniques to suppress sidelobes in SAR images to develop a higher‐fidelity measurement model. Using Cranfield University's GBSAR System a series, experimental measurements are conducted, and image estimation techniques are applied to this real data.

Speckle effect on polarimetric target scattering decomposition of SAR imagery
Canadian Journal of Remote Sensing, 2007 Target scattering decompositions have become the standard tools for scattering classification and for target geophysical parameter extraction from polarimetric synthetic aperture radar (SAR) data. Incoherent decompositions are based on the characteristic decomposition of the target coherency matrix and the use of its eigenvalues and eigenvector ...
