The Indispensable Role of Weather Data in Consumer Spending Prediction: A Robust Machine Learning Assessment
Published: 2025-08-01
Subjects: Climate, Environmental Indicators and Impact Assessment, Environmental Monitoring, Meteorology
Accurate forecasting of daily consumer spending is crucial for strategic decision-making in the retail sector, yet the dynamic influence of weather is often underestimated or insufficiently integrated into predictive models. This study presents a comprehensive evaluation of incorporating both historical and 7-day weather forecast data on predicting consumer spending amounts across three diverse [...]
Regionally divergent drivers behind transgressions of the freshwater change planetary boundary
Published: 2025-08-01
Subjects: Hydrology, Physical Sciences and Mathematics
Human-driven freshwater change contributes to elevated Earth system risks. Here, we advance the understanding of drivers behind the transgression of the planetary boundary for freshwater change (PB-FW), based on historical (1901–2019) streamflow (blue water) and soil moisture (green water) simulations from a large ensemble of global hydrological models. Since the former estimate ending in 2005, [...]

Mineral exploration can be done using the seven bands from Landsat8 satellite images, through combination of different maps, a specific color [...]
Extreme Environments of Latin America: Natural Laboratories for Astrobiology
Published: 2025-08-01
Subjects: Life Sciences
Extreme environments are places where sustaining life is considered challenging by human standarts due to harmful environmental conditions. In the last decades, these kinds of environments have awakened the interest of planetary scientists due to their similar conditions to extraplanetary bodies. Most of the research done in extreme environments has been conducted in the North American and [...]
Paleoseismology of the Zougahana fault, northern Aso outer rim, and its role in the tectonics of northern Kyushu
Published: 2025-07-31
Subjects: Geomorphology, Tectonics and Structure
The Kumamoto earthquake (Mj 6.5, Mj 7.3) occurred on 14 and 16 April 2016, with the epicenter on the Futagawa and Hinagu faults, central Kyushu Island, southwest Japan. Differential interferometric synthetic aperture radar analyses detected many phase discontinuities in the source region. Phase discontinuities and ruptures were also confirmed at the Zougahana fault on the northeastern rim of Aso [...]
Future Sea Ice-Ocean and Biological Productivity Changes in the North Water Polynya Region under Policy Relevant Warming Levels
Published: 2025-07-31
Subjects: Climate, Oceanography, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics
The North Water Polynya (NOW) is one of the most productive biological regions in the Arctic with high importance to Inuit and local communities of Nunavut and Greenland. To provide insights into the potential changes of this region as global temperatures rise, we investigated the sea ice, and physical and biological oceanic responses of the NOW to low (2 °C) and high (3.5 °C) levels of warming [...]
Assessing Indoor Versus Outdoor PM2.5 Concentrations During the 2025 Los Angeles Fires Using the PurpleAir Sensor Network
Published: 2025-07-30
Subjects: Engineering
In January 2025, a series of fast-moving wildland-urban-interface (WUI) fires swept through the Los Angeles (LA) metropolitan area, causing severe air pollution. While the impacts of WUI fires on outdoor air quality have been extensively studied, indoor exposure remains less understood, despite most people sheltering indoors during WUI fires. This study investigates the spatial and temporal [...]
Oxic methane production in shallow productive lakes: linking field and in vitro experimental evidence
Published: 2025-07-30
Subjects: Microbiology, Terrestrial and Aquatic Ecology
Whereas the occurrence of oxic methane (CH₄) production (OMP) in the oxygenated water column of lakes is widely accepted, its mechanisms, isotopic signature, and contribution to total CH₄ emissions remain uncertain. Evidence suggests that phytoplankton produces CH₄, but it is unclear to what extent this pathway contributes to ecosystem OMP rates. Shallow lakes are often productive and feature [...]
Experiments to Systematically Evaluate the Role of Cohesion in River Morphodynamics
Published: 2025-07-30
Subjects: Earth Sciences, Engineering, Engineering Science and Materials, Environmental Sciences, Materials Science and Engineering, Mechanical Engineering, Other Engineering, Social and Behavioral Sciences
While cohesion is thought to be an important control on sediment transport, few studies have systematically examined the role of cohesion in river morphodynamics. In this study we use simplified, small-scale laboratory experiments to investigate how increasing sediment cohesion affects the morphometrics of fluvial channels. Experiments were conducted in a laminar flume with a mixture of [...]
A novel experimental V-Sc olivine-melt oxybarometer for arc magmas
Published: 2025-07-30
Subjects: Earth Sciences, Geochemistry
Redox conditions significantly affect phase equilibria, the availability and mobility of heterovalent elements, including volatiles (i.e., S) and metals (e.g., Fe, Cu) in silicate melts. Gaining a deeper understanding of the initial redox state of magmas may help better understand magmatic ore fertility, volcanic degassing, and the redox evolution of Earth's crust and atmosphere. This study [...]
Characterizing point-source carbon emissions by combining TROPOMI CO and OCO CO2 data.
Published: 2025-07-30
Subjects: Earth Sciences, Environmental Sciences, Physical Sciences and Mathematics
Understanding and independently validating carbon emissions from concentrated point sources is vital to support climate policy. Satellite-based quantifications of CO2 point source emissions have been limited by the spatial coverage of current satellite instruments. We combine three different satellite instruments to determine carbon monoxide (CO) and carbon dioxide (CO2) emissions of seven large [...]
