Classifying cumulatively disadvantaged communities in California: A quantitative comparison of environmental justice screening tools
Published: 2025-01-11
Subjects: Environmental Health and Protection, Environmental Studies
Background: Government agencies at the state and federal levels have developed screening tools to classify disadvantaged communities, which are cumulatively burdened by social marginalization and environmental hazards. Status as a recognized disadvantaged community can determine access to public funding and protections associated with environmental justice policies. In California, multiple [...]

An updated version of the SZ-plugin: from space to space-time data-driven modeling in QGIS
Published: 2025-01-15
Subjects: Geology, Geomorphology, Software Engineering, Statistical Models
The geospatial community usually makes use of GIS environments to handle databases and pre-process their information. Actual analyses, especially data-driven ones, are performed outside GIS platforms. This interrupts the flow of information and the processing chain in a number of I/O operations that inevitably slow down the overall analytical protocols. The first version of the SZ-plugin [...]
Increasing risk of mass human heat mortality if historical weather patterns recur
Published: 2025-01-15
Subjects: Physical Sciences and Mathematics
The potential death toll of severe extreme heat events is crucial for climate risk analysis and adaptation planning but may not be captured by existing projections. We estimate this quantity for Europe using machine learning to calculate the intensity of historical heat waves if they occur at present or future global temperatures, combined with empirical exposure-response functions to quantify [...]
Climate change impacts on compound renewable energy droughts under evolving infrastructure in the Western United States
Published: 2025-01-14
Subjects: Oil, Gas, and Energy, Power and Energy, Sustainability
If renewable energy resources continue to become a larger part of the generation mix in the United States (U.S.), so does the potential impact of prolonged periods of low wind and solar generation, known as variable renewable energy (VRE) droughts. In such a future, naturally occurring VRE droughts need to be evaluated for their potential impact on grid reliability. This study is the first of its [...]
UrbanTALES: A Comprehensive LES Dataset for Urban Canopy Layer Turbulence Analyses and Parameterization Development
Published: 2025-01-15
Subjects: Physical Sciences and Mathematics
The urban canopy layer (UCL) exhibits complex, heterogeneous flow patterns shaped by urban geometry. Traditionally, research has relied on microscale simulations over limited and often idealized building arrays, leaving a need for more extensive datasets to capture the dynamics across diverse urban neighborhoods. Responding to this gap, we developed an extensive dataset, known hereafter as [...]
On the Definition of an Independent Stochastic Model for InSAR Time Series
Published: 2025-01-16
Subjects: Engineering, Physical Sciences and Mathematics
InSAR enables the estimation of displacements of (objects on) the Earth’s surface. To provide reliable estimates, both an independent stochastic and functional model are re- quired. However, the intrinsic problem of InSAR is that both are unknown. Here we propose an independent definition of the stochastic model, via an approximation scheme for the variance- covariance matrix for [...]
Hypereutrophication, Hydrogen Sulfide, and Environmental Injustices: Mechanisms and Knowledge Gaps at the Salton Sea
Published: 2025-01-16
Subjects: Earth Sciences, Environmental Studies, Physical and Environmental Geography, Physical Sciences and Mathematics
The Salton Sea, California’s largest lake, is undergoing significant environmental degradation, which has adverse health effects on nearby rural communities, who are primarily Latinx and Torres Martinez Desert Cahuilla Indian. Over the past two decades, the lake’s water levels have steadily dropped. Water conditions in the Sea, characterized by low oxygen and high nutrient levels, favor the [...]
Acoustic Doppler Current Profiler Measurements from Saildrones, with Applications to Submesoscale Studies
Published: 2024-10-25
Subjects: Oceanography
Characterizing submesoscale ocean processes requires high-resolution observations in both space O(1 km) and time O(1 hr). One way to resolve submesoscale features is to deploy multiple mobile platforms, such as Saildrones (SDs), to achieve high-resolution synchronous measurements, but this requires velocity accuracies of O(1 cm/s) to resolve submesoscale velocity gradients. In this study, we [...]
Influence and Prediction of Planetary Orbital Changes on Earth's Atmospheric Water Vapor Variations
Published: 2025-01-17
Subjects: Education, Physical Sciences and Mathematics
A few people have gradually realized that the superposition effect of different planets in the solar system on Earth under high-speed motion and dynamic equilibrium can sometimes trigger extreme natural disasters. Due to the relatively regular changes in the relative positions of the Sun, Moon, and Earth, this study considers these three planets as independent systems. The orbits of other planets [...]
OceanTracker 0.5: Fast Adaptable Lagrangian Particle Tracking in Structured and Unstructured Grids
Published: 2025-01-16
Subjects: Numerical Analysis and Scientific Computing, Oceanography, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics
Particle tracking is frequently used to compute particle movements within hydrodynamic ocean models; however, modelling millions of particles is computationally challenging. OceanTracker is designed to minimise the time required to obtain results from particle tracking. Firstly, by being computationally fast, it enables users to scale to large numbers of particles, thus obtaining better [...]
Spatio-temporal analysis of the extremes of precipitation and temperature in the capital cities of India
Published: 2025-01-15
Subjects: Other Physical Sciences and Mathematics
This study presents an analysis of extreme temperature and precipitation events in the capital cities of India during 40-years study period (1982-2022). Daily maximum temperature, minimum temperature, and rainfall from NASA-POWER were used to compute climate extreme indices, recommended by the Expert Team on Climate Change Detection and Indices (ETCCDI) and Expert Team on Sector-Specific Climate [...]
Multilingual Community Visualizations (MCV): A GIS Dashboard for Linguistic Research and NWS Operations
Published: 2025-07-23
Subjects: Atmospheric Sciences, Geographic Information Sciences, Geography, Social and Behavioral Sciences
The NWS is actively expanding its multilingual outreach to better serve the 68.8 million U.S. individuals who speak a language other than English at home. Among these, 26.3 million individuals with Limited English Proficiency (LEP) are of particular concern, as they often rely entirely on translated forecasts to make life-saving decisions. Yet identifying where these populations are concentrated [...]
Recent rise of water levels of Lake Nakuru, Kenya: Unraveling the Changing Precipitation Regime and its Climatic Drivers
Published: 2025-01-21
Subjects: Atmospheric Sciences, Civil and Environmental Engineering, Engineering, Environmental Engineering, Meteorology, Oceanography, Oceanography and Atmospheric Sciences and Meteorology
The Kenyan Rift Valley has experienced an abrupt and significant rise in its lake levels since 2010, followed by a more rapid rise since 2020. This paper examines the dynamic changes in precipitation patterns and their climatic drivers in the Kenyan Rift Valley region from 1981 to 2021, focusing on Lake Nakuru. Notably, in 2010, a pivotal change point in precipitation aligns with the rising water [...]
