Reimagining Multifunctional Green Space Design Approaches in Climate Resilient Cities
Published: 2026-09-04
Subjects: Environmental Health and Protection, Environmental Sciences, Sustainability
Urban landscapes exacerbate the impacts of extreme temperatures and weather, and are hotspots for air pollution, flooding, and temperature spikes. Natural systems such as multifunctional green spaces can play a key role in protecting vulnerable urban landscapes while also improving urban livability.
Automated identification, industrial attribution and conditional emission-rate quantification of recurrent CO enhancement source regions from TROPOMI observations
Published: 2026-09-03
Subjects: Atmospheric Sciences, Remote Sensing
The TROPOspheric Monitoring Instrument (TROPOMI) repeatedly measures global carbon monoxide (CO) total columns, but industrial CO studies generally begin with known cities or facilities; a general method is therefore needed to discover where enhancements recur globally. We developed an automated workflow that searches without facility coordinates. A weakly supervised model screens scenes for [...]
Simulation analysis method of drainage system of tideland paddy zone
Published: 2026-09-03
Subjects: Physical Sciences and Mathematics
The tideland paddy zone drainage system plays an important role in preventing flood damage and protecting the tideland paddy zone by draining the rainwater from the paddy zones and the surrounding catchments in good time. Therefore, scientific design of drainage system and accurate assessment of drainage capacity in tideland paddy zones are important for sustainable development in agricultural [...]
Modelling Winter Atmospheric River Frequency over the Western Himalayas Using Large-Scale Climate Modes Via Statistical Approach
Published: 2026-09-03
Subjects: Engineering, Physical Sciences and Mathematics
Winter Atmospheric Rivers (ARs) contribute substantially to precipitation in the Western Himalayas, but how large-scale climate modes jointly influence their frequency remains unclear. In this study, we use a statistical method that combines correlation, phase-composite analysis of Integrated Vapor Transport (IVT), and predictive models such as linear regression, Generalized Linear Models (GLMs), [...]
The importance of ice shelf melt rate distributions in modelling of Antarctic ice loss
Published: 2026-09-03
Subjects: Environmental Sciences, Glaciology, Oceanography, Physical Sciences and Mathematics
Ocean-induced basal melting of ice shelves is a major cause of Antarctic ice loss. It is well known that the magnitude of this melt is an important factor to consider when modelling the future evolution of the ice sheet, and values of total melt volume or mean melt rates are often quoted for ice shelves. The finer detail of the distribution of this melt is usually given less attention. Here we [...]
Evaluating forecast baselines and network representativeness for daily PM2.5 in the Kathmandu Valley, Nepal
Published: 2026-09-03
Subjects: Atmospheric Sciences, Climate, Environmental Indicators and Impact Assessment, Environmental Monitoring, Meteorology
An order-fair attribution of daily PM2.5 predictability in the Kathmandu Valley assigns 72% of achievable error reduction to persistence, 19% to meteorology and 9% to day-of-year climatology, with the latter two largely redundant; no fitted model, including random forests and gradient boosting tuned by nested chronological cross-validation, outperforms an unfitted lag-1 forecast (11.22 µg m-3). [...]
Multi-Sensor Satellite-Based Retrospective Early-Warning Assessment of the 26 August 2026 Flood Event in the Langtang Region of Nepal
Published: 2026-09-03
Subjects: Earth Sciences, Environmental Sciences
Rapid-onset floods in high-mountain environments can be difficult to anticipate because their triggering mechanisms may involve interactions among precipitation, glacierized terrain, surface-water dynamics, and sudden geomorphological disturbances. This study presents a retrospective multi-sensor satellite assessment of the flood event reported in the Langtang region of Nepal on 26 August 2026. [...]
Fault roughness as a driver of rupture complexity in fluid-induced microearthquakes
Published: 2026-09-03
Subjects: Physical Sciences and Mathematics
Subsurface fluid-injection can induce microearthquakes whose rupture complexity and arrest mechanisms remain poorly understood, limiting our ability to assess the seismic hazard associated with geo-energy applications. We investigate how fault roughness modulates the response of fluid-pressurized faults using an ensemble of 1395 3D dynamic rupture simulations on self-similar rough faults, varying [...]
The Elastic Stiffness C13 in Transversely Isotropic Shales
Published: 2026-09-03
Subjects: Earth Sciences, Physical Sciences and Mathematics
Shales are often anisotropic due to fine-scale layering and preferred alignment of clay particles with bedding. They may be approximated as transversely isotropic (TI) media with symmetry axis (x3) perpendicular to bedding. TI media have five independent elastic stiffnesses C11, C33, C55, C66 and C13, with C12 = C11−2C66. While C11, C33, C55 and C66 may be estimated from velocities measured [...]
ENSO, weather regimes, and U.S. heating degree days
Published: 2026-09-03
Subjects: Oceanography and Atmospheric Sciences and Meteorology
Heating degree days (HDDs; the number of degrees by which average daily temperature falls below 65°F) quantify heating demand and are used to manage weather-related financial risk. Here we examined the relation of El Niño–Southern Oscillation (ENSO) with U.S. cold-season HDDs over the period 1979–2026 in NOAA Climate Division data and observations from stations that are used to settle publicly [...]
Airborne Metal Toxin Particulate Signatures and Legacy at Wildland–Urban Interface
Published: 2026-09-03
Subjects: Medicine and Health Sciences, Physical Sciences and Mathematics
Wildland–urban interface (WUI) fires burn urban materials together with soil and vegetation, generating air pollution as smoke during active burning and as resuspended dust during recovery. Here, we combine size-resolved sampling of the Eaton Fire (Altadena, CA) with controlled resuspension of materials collected from properties affected by the Eaton and Palisades (Pacific Palisades, CA) fires. [...]
A Framework for Experiential Environmental Health Through Theater
Published: 2026-09-03
Subjects: Education, Life Sciences, Physical Sciences and Mathematics, Social and Behavioral Sciences
Extreme weather events, including wildfires, are becoming more frequent, intense, and consequential for human health. Scientific advances have improved our ability to characterize hazards and the socioeconomic constraints shaping exposure, but these dimensions are not always integrated throughout the development of environmental health knowledge. Meanwhile, broader publics, although often not [...]
Sea-Level Change in Asia since the Last Glacial Maximum
Published: 2026-09-03
Subjects: Earth Sciences, Environmental Sciences, Physical Sciences and Mathematics
As a ‘far-field’ area, distal from former ice sheets, Asia is minimally influenced by the glacial isostatic adjustment process. Therefore, Relative sea-level (RSL) data from Asia, recorded by various geological proxies, provide essential constraints on the history of ice-equavilent sea-level changes. The global mean sea-level has risen over 130 m on average since the Last Glacial Maximum (LGM), [...]
