Growing wildfire-derived PM2.5 across the contiguous U.S. and implications for air quality regulation

Marissa Childs, Mariana Martins, Andrew Wilson, et al.

Published: 2024-12-09
Subjects: Environmental Sciences, Environmental Studies

Growing wildfire activity across North America produces significant smoke, undermining efforts to regulate surface air quality and protect public health. Using surface measurements, satellites, and machine learning, we provide granular, daily estimates of smoke PM2.5 concentrations in the contiguous U.S. from 2006 to 2023, and use them to assess the implications of smoke for surface air pollution [...]

WMSAN Python Package: From Oceanic Forcing to Synthetic Cross-correlations of Microseismic Noise

Lisa Tomasetto, Pierre Boué, Fabrice Ardhuin, et al.

Published: 2024-12-09
Subjects: Physical Sciences and Mathematics

Seismic ambient noise spectra show ubiquitously two amplitude peaks corresponding to distinct oceanic wave interaction mechanisms called primary (T≈ 14s) and secondary (T ≈ 7s) microseismic peaks. Seismic noise records are used in a wide range of applications, including crustal monitoring, imaging of the Earth’s deep interior using noise correlations, and studies on the coupling between oceans [...]

Theory and Conditions for AI-Based Inversion Paradigm of Geophysical Parameters Using Energy Balance

Kebiao Mao, Chenhao Wu, Zijin Yuan, et al.

Published: 2024-12-08
Subjects: Engineering, Physical Sciences and Mathematics

To construct a universal artificial intelligence (AI) model for geophysical parameter inversion, this study proposes a new remote sensing parameter inversion paradigm theory by changing cognition to unify physical, statistics and AI methods. Using the energy balance equation, we demonstrate that establishing a closed system of physical inversion equations between input and output variables in [...]

Seismic Data Interpretation of the Rashidpur Anticline: Implications for Structural Analysis and Trapping Mechanisms

Fatimatuzz Zohora Farzana, Rashed Abdullah

Published: 2024-12-07
Subjects: Physical Sciences and Mathematics

The Rashidpur anticline, trending N-S, is a surface anticline with reverse faulting located in an area characterised by low hillocks. It is part of the youngest structural province along the western flank of the Indo-Burman Ranges, formed by the oblique subduction of the Indian plate beneath the Burmese plate. Many folds in the area are influenced by faults along their axes. Seismic transect [...]

Tracking Drought Impacts from Texts: Towards AI-Assisted Drought Impact Detection

Beichen Zhang, Kelly Helm Smith, Frank Schilder, et al.

Published: 2024-12-07
Subjects: Artificial Intelligence and Robotics, Computer Sciences, Earth Sciences, Environmental Indicators and Impact Assessment, Environmental Sciences, Hydrology

Drought is recognized for its extensive and varied impacts. Based on the drought-related textual datasets from the National Drought Mitigation Center, our research applies advanced artificial intelligence techniques, including deep learning and natural language processing, to enhance the monitoring of multifaceted drought impacts in the United States. This study also delves into predicting [...]

Easing population to 4 billion by 2200 would help people and nature

Mark Keegan

Published: 2024-12-07
Subjects: Environmental Studies

The past century of increases in human population and resource consumption has produced some undesirable effects, ranging from environmental degradation to climate change to political unrest. We are accustomed to seeing these dependent variables charted with time on the x-axis. But this study presents metrics of biodiversity, consumption, and pollution and their extremely strong correlations when [...]

Innovation-based Methods for Estimating Observation Error Variances During Ensemble Data Assimilation

Comprehensive global dataset of 300,000 uniformly processed shear-wave splitting measurements with regular updates

Jonathan Wolf, Thorsten W. Becker, Ed Garnero, et al.

Published: 2024-12-06
Subjects: Physical Sciences and Mathematics

Seismic anisotropy can inform us about convective flow in the mantle. Shear waves traveling through azimuthally anisotropic regions split into fast and slow pulses, and measuring the resulting shear-wave splitting provides some of the most direct insights into Earth’s interior dynamics. Shear-wave splitting is a constraint for path-averaged azimuthal anisotropy and is often studied regionally, [...]

Global industrial disruption following nuclear war

Simon Blouin, Florian Ulrich Jehn, David Denkenberger

Published: 2024-12-05
Subjects: Agriculture, International and Area Studies, Other Geography, Risk Analysis

Nuclear war poses catastrophic risks not only through its immediate effects and potential nuclear winter, but also through the disruption of industrial production on which modern civilization depends. In this study we estimate the reduction in global industrial output following a US-Russia nuclear war, as well as a more limited India-Pakistan exchange, by combining geospatial analysis with [...]

Harmonised airborne laser scanning products can address the limitations of large-scale spaceborne vegetation mapping

Vítězslav Moudrý, Ruben Remelgado, Matthias Forkel, et al.

Published: 2024-12-04
Subjects: Life Sciences

Vegetation structure data are essential for understanding the functioning of terrestrial ecosystems and for informing various science-policy interfaces. Recent years have seen a growing demand for high-resolution data on vegetation structure, driving the prediction of such metrics at fine resolutions (1 m - 30 m) at state, continental, and global scales by combining satellite data with machine [...]

Smoke in your eyes: Investigating the effects of wind power on weather trends and climate using time series analysis

Keith Michael Johnson

Published: 2024-12-04
Subjects: Climate

Time series analysis developed in the previous report [1] for UK mean summer temperature has been applied to further examples of weather trends, including temperature, rainfall and Sahara dust, and so at global, regional, national and local levels, in an attempt to assess whether wind power is having a deleterious effect on weather patterns. The analysis involves detrending weather data by [...]

Investigating the recommendations and governmental actions to address the emerging risks of vector-borne diseases in Canada’s changing climate: A scoping review

Renée Schryer, Michala Norman, Manisha A. Kulkarni

Published: 2024-12-04
Subjects: Public Health

Climate change is expected to increase the risks associated with vector-borne diseases, and its implications for human health are already observed across Canada. The objective of this review was to investigate the recommended adaptation strategies related to the risks associated with vector-borne diseases and examine how various levels of government in Canada are executing these recommended [...]

A Millimeter-Scale Change in Leaf Litter Placement Within Soil-Water Interfaces Alters Carbon Dioxide and Methane Emission

Hao Liu, Yi-Ning Zhang, Yu-Jia Cai, et al.

Published: 2024-12-04
Subjects: Earth Sciences, Environmental Sciences, Geochemistry, Soil Science, Sustainability

Flooded soils play a critical role in global carbon cycling, serving as significant reservoirs of soil organic carbon and sources of carbon emissions. Leaf litter, particularly from local vegetation, is a major contributor to soil organic carbon formation in these ecosystems, with its decomposition driving the production of carbon dioxide and methane. While numerous studies have investigated the [...]

Intensifying tropical cyclones associated with more frequent hazardous material pipeline failures

Elizabeth Carter, Marilyn Smith

Published: 2024-12-04
Subjects: Engineering

Over 30,000 hazardous material pipeline (HMP) failures have been reported in the US since 1970, associated with 274 fatalities, 1,120 injuries, and nearly $11 billion in damages. Tropical cyclones are under-recognized as drivers of pipeline failures, mainly because failures aren't associated with tropical cyclones on operator-generated incidence reports, limiting analysis. This study defines [...]
