Survey of Transverse Range Fire Scars in 10 Years of UAVSAR Polarimetry [PDF]

open access: yesEarth and Space Science, 2021
Because cross‐polarized radar returns are highly associated with volume scatter, radar polarimetry returns tend to show strong evidence of wildfire scars and recovery in forest and chaparral.

Principal Component Analysis In Radar Polarimetry [PDF]

open access: yesAdvances in Radio Science, 2005
Second order moments of multivariate (often Gaussian) joint probability density functions can be described by the covariance or normalised correlation matrices or by the Kennaugh matrix (Kronecker matrix).

Advancing Earth System Science With the NASA Plankton, Aerosol, Cloud, Ocean Ecosystem (PACE) Satellite Mission [PDF]

open access: yesGlobal Change Biology, Volume 32, Issue 4, April 2026.
The Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission extends and improves upon NASA's 30+ years of satellite observations of Earth's living ocean, atmosphere, and land. Its unprecedented, high‐resolution data support critical research in climate forcing, ecosystem health, and biogeochemical cycling, while aiding socioeconomic applications such ...

Polarimetric Wide‐Angle Radar Detects Competing Signatures of Ice Fabric and Structural Firn Anisotropy

open access: yesGeophysical Research Letters
Ice is mechanically and dielectrically anisotropic. The degree of anisotropy evolves dynamically as ice crystals align during deformation into macroscopic patterns termed ice fabric.

Graphene‐based metasurface: dynamic optical control in ultrathin flat optics [PDF]

open access: yesNanophotonics, Volume 14, Issue 12, Page 2103-2132, June 2025.
Abstract Graphene hosts massless Dirac fermions owing to its linear electronic band structure. This distinctive feature underpins its extraordinary electronic properties, correlating to strong light–matter interactions on an extreme subwavelength scale. Over the past decade, intensive investigations have transitioned from fundamental graphene’s optical

Application of Microwave Polarimetry to the Characterization of Fiber Misalignment in Composites

open access: yesIEEE Open Journal of Instrumentation and Measurement, 2022
In this paper synthetic aperture radar (SAR) polarimetry techniques are applied to detect and characterize fiber misalignment in both carbon fiber sheets and glass fiber reinforced polymer (GFRP) composites. The principle behind SAR polarimetry technique

Dual-Polarization Radar Fingerprints of Precipitation Physics: A Review

open access: yesRemote Sensing, 2022
This article reviews how precipitation microphysics processes are observed in dual-polarization radar observations. These so-called “fingerprints” of precipitation processes are observed as vertical gradients in radar observables.
