Published: 2026-02-28
Subjects: Engineering
This research integrates existing cyberinfrastructure tools and modeling workflows to support application of the Next Generation Water Resources Modeling Framework (NextGen) for research-scale subdomains across the U.S. We linked the CUAHSI HydroShare data and model repository to the CIROH 2i2c-JupyterHub cloud computing platform to establish a flexible, scalable collaborative environment for [...]
Evaluation of high-resolution gridded climate products in reproducing spatial and temporal variation in precipitation in central Panama
Published: 2026-02-28
Subjects: Earth Sciences, Environmental Sciences
Tropical forests vary widely in their precipitation regimes and seasonal water availability, but high-quality in-situ (ground-based) meteorological data are rare, and few studies have evaluated the performance of global gridded climate products in the tropics. We compared the performance of eleven high-resolution gridded climate products against in-situ datasets spanning high rainfall variation [...]
From Roots to Canopy: An Evolving Framework for Critical Zone Education and Outreach
Published: 2026-02-28
Subjects: Education, Educational Methods, Higher Education, Science and Mathematics Education
Critical Zone (CZ) science provides an integrative framework for understanding the Earth as an interconnected system spanning from the vegetation canopy through soils and weathered rock to groundwater. While the CZ concept has become foundational within earth and environmental sciences, it remains unfamiliar to many educators, students, and community audiences. This paper presents the evolution [...]
Multi-Parametric Assessment of Avian Biodiversity and Anthropogenic Disturbance for Conservation Prioritization in Belize
Published: 2026-02-28
Subjects: Life Sciences, Physical Sciences and Mathematics
Background: Anthropogenic climate change and rising levels have accelerated global warming, causing severe disruptions to Belizean ecosystems through sea-level rise and habitat fragmentation. To mitigate these impacts, identifying high-value land for protected status is a critical conservation priority for maintaining medicinal biodiversity and preventing zoonotic disease spillover. Objective: [...]
Mutual interactions between aquifer thermal energy storage and groundwater extraction: global sensitivity insights
Published: 2026-02-27
Subjects: Hydrology
Aquifer Thermal Energy Storage (ATES) is increasingly deployed in groundwater protection zones, motivating a quantitative assessment of thermal impacts on public-supply wells and the influence of supply-well pumping on ATES performance. In the Campine Basin (Belgium), we simulate three settings: balanced operation, seasonal imbalance, and multi-system deployment. Using a groundwater flow and [...]
Declining Snowpack in the Presence of Stable Precipitation May Not Negatively Impact Baseflow or Floodplain Vegetation in the Middle Fork Rock Creek Watershed, Montana, USA
Published: 2026-02-27
Subjects: Earth Sciences, Environmental Monitoring, Environmental Sciences, Hydrology, Natural Resources and Conservation
In the age of snow droughts and megafires, water availability and changes in precipitation, snowpack, and baseflows are active areas of research. Headwater streams are where all large rivers begin, but their seasonal water availability is difficult to measure because they are so abundant and remote. Remote sensing can help monitor small streams semi-arid areas if there is an appropriate proxy for [...]
Dynamic critical groundwater depth as a predictor of irrigation-intensified salinization in lowland Hungary
Published: 2026-02-27
Subjects: Agriculture, Hydrology, Soil Science
Shallow groundwater in continental lowland environments sustains upward capillary fluxes that transport dissolved salts to the land surface. However, the depth below which this capillary-driven contribution becomes negligible, often parameterized as the extinction depth in groundwater model ET packages, has been treated as a static, soil-dependent parameter. We argue that salinization risk is [...]
Structural Shifts in Urban Air Pollution Patterns in Trinidad After COVID-19: Evidence from Diurnal and Weekday/Weekend PM Profiles, 2022-2024
Published: 2026-02-27
Subjects: Physical Sciences and Mathematics
The COVID-19 pandemic temporarily reduced air pollution by disrupting human mobility. This study tests whether particulate pollution patterns in Trinidad and Tobago underwent lasting structural change during the post-pandemic period 2022-2024. We analyse continuous PM₂.₅ and PM₁₀ observations from four Environmental Management Authority monitoring sites representing distinct source environments: [...]
SpecFWAT: Specfem3D-based Full-waveform Adjoint Tomography Package for High-resolution Lithospheric Imaging
Published: 2026-02-27
Subjects: Geophysics and Seismology
We present SpecFWAT, a high-performance, open-source software package designed for full-waveform adjoint tomography at the lithospheric scale using multiple data types. Building upon the spectral-element forward solver SPECFEM3D, SpecFWAT introduces a modernized inversion framework featuring an object-oriented Fortran design and a CMake-based build environment. To enhance usability and [...]
High-resolution agent-based modelling of non-exhaust emissions reveals the limits of urban fleet electrification
Published: 2026-02-26
Subjects: Environmental Health and Protection
As exhaust emissions decline, non-exhaust emissions (NEEs) from brake and tyre wear are emerging as the dominant source of traffic-related particulate matter. This transition is complicated by the increasing mass of electric vehicles and the push toward high-capacity public transport. We introduce a high-resolution, moving-observer agent-based model calibrated against hyperlocal Google Air View [...]
Error-aware surrogate modeling for accelerated three-dimensional probabilistic inversion of controlled-source electromagnetic data
Published: 2026-02-26
Subjects: Education, Physical Sciences and Mathematics
We present a workflow for three-dimensional probabilistic inversion of controlled-source electromagnetic data that effectively balances accuracy and computational efficiency. The approach mitigates the high computational cost of forward modeling by employing a surrogate model derived from a mesh coarsening strategy. To account for the modeling errors inherent to this approximation, we implement a [...]
Foreshock Acceleration Linked to Slow Earthquakes Before a Large Earthquake: Implications for Two-Stage Aseismic Processes
Published: 2026-02-26
Subjects: Physical Sciences and Mathematics
Foreshocks are important for understanding the initiation process of large earthquakes. It has long been suggested that the acceleration of foreshock activity is driven by precursory aseismic fault slip. However, observational evidence supporting this relationship remains limited. Furthermore, while slow earthquakes—diverse low-velocity fault slip phenomena—frequently occur at plate boundaries, [...]
Paleo- and Neo-Tethyan subducted slabs below the Eastern Mediterranean region
Published: 2026-02-25
Subjects: Earth Sciences, Physical Sciences and Mathematics
The late Paleozoic to recent Alpine-Himalayan orogen contains the geological remnants of subducted lithosphere of the Paleotethys and Neotethys oceans and of microcontinents within these. This orogenic belt is segmented by abrupt along-strike changes that according to plate reconstructions coincide with paleo-transform faults across which oceanic opening and subduction histories changed. Here, we [...]
