Digital elevation models and their use for assessing soil erosion rates on arable lands

Учёные записки Казанского университета: Серия Естественные науки, 2018
The paper presents the results of assessing the accuracy of global digital elevation models (GDEMs), SRTM and ASTER GDEMs, based on a small catchment located on the eastern slope of the Central Russian Upland in the upper reaches of the Veduga River ...

Strategic Roadmap for Addressing Microplastic Pollution in the Global South: Bridging Monitoring Gaps, Harmonizing Methods, and Building Analytical Capacity

Environmental Quality Management, Volume 35, Issue 4, Summer 2026.
ABSTRACT Microplastic (MP) pollution represents a growing environmental challenge, especially in tropical and subtropical coastal regions of the Global South, where methodological fragmentation, funding discontinuity, and dependence on external analytical infrastructure limit the production of comparable data and the formulation of evidence‐based ...

Controls on Valley‐Floor Width in the Western Andes

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract River‐valley floors are low relief, confined parts of the landscape that store sediment en route from mountains to lowlands. Transient sediment storage influences sediment budgets, biogeochemical cycles, and the preservation of environmental signals. The controls on valley‐floor width remain poorly understood, limiting the ability to reproduce

The Decline of a Caldera‐Filling Glacier at Volcán Sollipulli, Chile

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Southern Andean glaciers have undergone fast retreat in recent decades. This results in reduced freshwater storage, contribution to sea‐level rise, and locally to the formation of glacial lakes, that may pose the risk of glacial lake outburst floods (GLOFs).

Multi‐Model Ensemble Knowledge Distillation With Physics Constraints for Numerical Weather Prediction Bias Correction

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Accurate Numerical Weather Prediction (NWP) is of paramount importance for global climate change response and sustainable development. Although numerical models such as the Weather Research and Forecasting (WRF) model are widely applied in operational forecasting, they exhibit significant systematic biases under complex atmospheric conditions,

DEM based examination of pediment levels: a case study in Bükkalja, Hungary

Hungarian Geographical Bulletin, 2011
Bükkalja is the southern pediment of Bükk Mountains. According to the geographic literature this area is divided into two pediment (geomorphic) levels.

Reconstructing Digital Elevation Models From Single Synthetic Aperture Radar Images

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Traditional radar‐based methods of generating topography involve complex dual‐antenna or formation‐flying satellite configurations, interferometric processing, and specialized expertise. We present an approach for reconstructing digital elevation models (DEMs) from single Synthetic Aperture Radar (SAR) images using deep learning.

Structural Recovery of Overlooked Shrublands Drives Asymmetric Restoration in Dryland Ecosystems

Earth's Future, Volume 14, Issue 6, June 2026.
Abstract Current remote sensing of dryland ecosystems is fundamentally limited by a reliance on vegetation indices (“greenness”), which struggle to disentangle mixed pixel signals and fail to capture the non‐photosynthetic structural components critical for resilience.

Resampling SRTM 03”-data with kriging

, 2017
The purpose of this article is to present the steps necessary to improve the resolution of a DEM us- ing variogram modelling and kriging, as well as a brief comparison of the results with those obtained with interpolation by Regularised Splines with Ten- sion (RST).

No safe refuge? Contrasting effects of hunting on rainforest mammal persistence and (re)colonisation

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Our results imply that hunting not only targets areas used as refuges by wildlife, but also reduces recolonisation potential and may therefore alter source–sink dynamics. We recommend spatially targeted community‐led actions to limit hunting where wildlife still persists through the creation of no‐hunting areas to ensure the long‐term persistence of ...
