Measurement and Analysis of Multiband Bistatic and Monostatic Radar Signatures of Wind Turbines [PDF]

This paper presents the results of recent measurements taken with two radar systems to measure the simultaneous monostatic and bistatic signature of wind turbines, at S-band and X-band.

A Simple Method of Estimating Wave Height Based on Shadowing in X-Band Radar Images

Journal of Marine Science and Engineering
X-band marine radar shadow features are widely applied to wave height estimation. Since the shadow fraction rises with the distance from the radar antenna, wave slope estimation is sensitive to the selected analysis region.

From Surface to Depth: SWOT Altimetry and Glider Observations of a Cuddy in the Northeast Pacific

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract California Undercurrent Eddies (Cuddies) transport heat, salt, and biogeochemical properties from coastal regions to the open Northeast Pacific, but their three‐dimensional structure, lateral exchange mechanisms and complete life‐cycle are still not fully understood.

3D Architecture of Kodiak Butte as Evidence of Fluvial or Shoal‐Water Environments in Jezero Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The Mars 2020 mission has explored depositional environments recorded in a fan‐shaped deposit on the western side of Jezero crater. Kodiak butte is an isolated outcrop of sedimentary rock ∼1 km south of the western fan scarp and may be an erosional remnant of said fan.

Relating Monthly to Yearly Morphological Changes in Embryonic Coastal Dune Systems

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Embryonic coastal dunes are dynamic morphological features shaped by wind, waves, sediment availability, and vegetation. Temporal variability in these drivers controls embryo dune dynamics at short timescales (hours–days), while accreting dune systems often show gradual change over longer timescales (years–decades).

The SARTOM Project; Tomography for enhanced target detection for foliage penetrating airborne SAR [PDF]

, 2008
The SARTOM project addresses a key area of defence interest, namely the detection and identification of targets hidden in foliage. The project has provided a rich source of data obtained from a series of flight trials that were conducted in September ...

Enhancing Significant Wave Height Simulations Using Distribution‐Aware Deep Learning and Environmental Predictors

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Numerical wave models are widely used for wave forecasting and hindcast data set construction; however, their outputs frequently exhibit systematic biases stemming from uncertainties in wind forcing, physical parameterizations, and bathymetry. To address this issue, a deep learning–based bias correction approach is applied to significant wave ...

Diffusion‐Based Reconstruction of Western North Pacific Surface Winds From CYGNSS for Tropical Cyclone Analysis

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 10, October 2026.
Abstract Sea surface wind retrieval under extreme weather conditions is constrained by the sparse and irregular spatiotemporal sampling of Global Navigation Satellite System Reflectometry (GNSS‐R). This study presents a probabilistic wind field reconstruction framework for the Western North Pacific using Score‐Based Data Assimilation (SDA). A diffusion

Observation of Shortwave Fadeout Events Using Chinese Dual Auroral Radar Network (CN‐DARN) During the Severe Solar Storm in May 2024

Space Weather, Volume 24, Issue 10, October 2026.
Abstract Shortwave fadeout (SWF) is a typical dayside high‐frequency radio disturbance caused by solar flare‐induced ionospheric ionization enhancement. Using newly built Chinese Dual Auroral Radar Network (CN‐DARN) observations, we investigate two X‐flare‐driven SWFs during the May 2024 geomagnetic superstorm (SYM‐H = −518 nT), on 10 May (pre‐storm ...
