Statistical Downscaling of Future Temperature in Tianshan Mountains Based on Batch Gradient Descent Nonlinear Regression

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Temperature is a key variable in alpine regions such as the Tianshan Mountains, which affects the population and economic development in lowlands by regulating the melting of snow and glaciers. The climate change over the Tianshan Mountains may have a strong climate impact.

A Joint Inversion Algorithm of GNSS and InSAR for Continuous 3‐D Surface Velocities and Associated Horizontal Strain Rate Field

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Simultaneous analyses of complementary GNSS and InSAR measurements may lead to breakthroughs in our understanding of crustal deformation. We present an algorithm that combines InSAR with GNSS measurements, in which the GNSS data can be used either as original station velocities or as an interpolated and smoothed velocity field, to estimate ...

Fault Stability Assessment in Tectonically Active Geothermal Fields Through Integrated Stress Analysis

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The Tulu Moye geothermal field in the actively deforming Main Ethiopian Rift presents substantial potential for renewable energy production, where interactions between fault systems, hydrothermal fluids, and tectonic activity require careful management for sustainable development. Here we present a first‐order assessment of fault stability and

Improved land cover mapping using aerial photographs and satellite images

Open Geosciences, 2014
Manual Land Cover Mapping using aerial photographs provides sufficient level of resolution for detailed vegetation or land cover maps. However, in some cases it is not possible to achieve the desired information over large areas, for example from ...

Sensitivity of Flood Extent and Population Exposure to Variations in Bathymetry Across a Shallow Continental Shelf Lagoon

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Bathymetry is a critical input to storm surge models on coastlines fronted by lagoon systems, yet few studies explore how variations in bathymetry influence flood impacts, flooded extent, and exposed population across these globally widespread morphologies.

An evaluation of EU-DEM in comparison with ASTER GDEM, SRTM and contour-based DEMs over the Eastern Mecsek Mountains

Hungarian Geographical Bulletin, 2014
The availability of global coverage digital surface models (like ASTER GDEM or SRTM) and the variation of fused models based on these (like EU-DEM) still has a great impact on scientific researches, as they provides a fairly good base dataset with a low ...

Radio Propagation in Railway Corridors Through Dense Forests–Measurement and Modeling at 460 MHz

Radio Science, Volume 61, Issue 3, March 2026.
Abstract Current train signaling systems are being replaced by advanced systems like Communications‐Based Train Control, European Rail Traffic Management System, and Positive Train Control, which rely on radio networks. However, railways operating in dense forest environments face unique challenges for wireless systems due to high levels of signal ...
