Rethinking Collinearity in Self‐Organizing Maps: Evidence From Geophysical Data Classification

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract This study examines the impact of collinearity on unsupervised machine learning algorithms (UMLAs), specifically Self‐Organizing Maps (SOMs), for detecting lithological boundaries in geophysical data. Using a multi‐scale experimental framework that includes bivariate isotropic clusters, geologically complex Noddy simulations, and real‐world ...

Daily multi-time monitoring of SLST jointly using FY-3 dawn-dusk and afternoon orbit satellite data with 250 m resolution

International Journal of Digital Earth
Snow/land surface temperature (SLST) has a significant impact on snow melting, metamorphism, and land-atmosphere energy exchange. It is also an important factor that affects outdoor skiing during the Olympic Winter Games (OWG).

U/Th Dating of Secondary Carbonate Deposits in Underground Galleries of Fourvière Hill (Lyon, France) Reveals a Water Supply System in Operation From the Roman Period to the Middle Ages

Archaeometry, Volume 68, Issue 2, Page 286-295, April 2026.
ABSTRACT The recent discovery of a water draining structure known as the Antiquaille galleries in Fourvière hill, in the center of Lyon, France (ancient Lugdunum), sheds light on the water drainage system built by the former inhabitants of this area for their water needs.

Estimating Net Sediment Fluxes in Tidal Systems Using Sporadic Data Sets: Implications for Using Remote Sensing to Assess Saltmarsh Resilience

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Sediment budgets are diagnostic of saltmarsh resilience, yet quantifying net sediment fluxes remains constrained by limited, asynchronous observations of suspended sediment concentration (SSC) and water flux. Using high‐frequency observations from 15 U.S.

Monte Carlo Simulation of 3D Cloud Radiance Distributions Affected by Ground‐Based Lighting

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Satellite observations of artificial light sources at night are increasing. Clouds, as the most important radiative modulators in the Earth‐atmosphere system, significantly influence the observed values and spatial distribution of the artificial light coming from the ground.
