Comparative Impact Assessment of Climate Change and Land-Use Alteration on Decadal Water Balance Components: A Case Stu…
Water Balance Components (WBCs), the most fundamental processes of a river basin, are getting disturbed by climate change and land-use alterations in the present scenario. These t…
Quantifying the Permafrost Heat Sink in Earth's Climate System
Due to an imbalance of incoming and outgoing radiation at the top of the atmosphere, excess heat has been accumulating in Earth’s climate system in recent decades, driving global …
Mineralogy, morphology, and emplacement history of the Maaz formation on the Jezero crater floor from orbital and rover…
The first samples collected by the Perseverance rover on the Mars 2020 mission were from the Maaz formation, a lava plain that covers most of the floor of Jezero crater. Laborator…
Rapid Formation of Abiotic CO 2 Results from Additions of a Simple Phenolic, Gallic Acid, to Soil
Abiotic efflux of CO 2 from soil is often attributed to dissolution of carbonates, and therefore not expected to occur in soils with a low pH. However, another abiotic source of C…
Cross-scale Probabilistic Storm Surge and Tide Forecasts: Impacts of Tropical Cyclone Wind Field Structure
We present UPSurgeML, a cross-scale framework for probabilistic storm surge and tide forecasting driven by tropical cyclones (TCs), consisting of a small ensemble of unstructured-…
Deep learning unlocks satellite-based monitoring of the global ocean overturning circulation
The meridional overturning circulation (MOC) is a key regulator of Earth’s climate and is sensitive to anthropogenic warming. Yet observations remain limited to a few Atlantic lat…
Bridging Event-Based and StorAge Selection Approaches to Backward Travel Time Distributions
Event-based backward travel time distributions (bTTDs) derived from tracer impulse responses provide event-scale insight into catchment transport, while StorAge Selection (SAS) fu…
Nitrification and nitrous oxide production in the offshore waters of the Eastern Tropical South Pacific
Marine oxygen deficient zones (ODZs) are dynamic areas of microbial nitrogen cycling. Nitrification, the microbial oxidation of ammonia to nitrate, plays multiple roles in the bio…
Structure of pre-monsoon convective systems over a tropical coastal region in southwest India using C-band polarimetric…
The structure of pre-monsoon convective systems over southern peninsular India using polarimetric doppler weather radar (DWR) observations has been analyzed. Convective-stratiform…
Influence of Observational Datasets on ECS and TCR Estimates
Uncertainties in estimates of Equilibrium Climate Sensitivity (ECS) and Transient Climate Response (TCR) are influenced by observational datasets. Variability exists not just amon…
In-situ regolith seismic velocity measurement at the InSight landing site on Mars
InSight’s seismometer package SEIS was placed on the surface of Mars at about 1.2 m distance from the thermal properties instrument HP3 that includes a self-hammering probe. Recor…
Adiabatic temperature profile in the mantle, revised
This study re-evaluates the adiabatic temperature profile of the Earth’s mantle. The global average temperature at the 410-km discontinuity is estimated to be 1805(18) K by compar…
Microplastics, road dust, and biological particles drive hazardous urban ice fog formation
Ice fog is a common form of air pollution that forms at low temperatures and poses extreme hazards for aircraft and automobile travel, particularly in high-latitude environments. …
The Global Conductivity Structure of the Moon
Magnetic sounding is a powerful tool to explore the interior of planetary bodies through the electrical conductivity structure. The electrical conductivity structure of the lunar …
A Late Cretaceous-Eocene Geomagnetic Polarity Time Scale (MM26) that combines marine magnetic anomaly records, radioiso…
The Geomagnetic Polarity Time Scale (GPTS) is essential to date geological events in stratigraphic sequences and to reconstruct plate motions. The first GPTSs were based on the re…
Regime transition in rotating convection driven by inner-core boundary thermochemical coupling
Convection in Earth’s liquid outer core is powered by a combination of thermal and compositional buoyancy released at the inner-core boundary (ICB). The interaction between these …
Can the Moon's Center of Mass–Center of Figure Offset Be Explained With a Uniform Primordial Crust?
A fundamental constraint on the Moon's interior mass distribution is the 1.935-km lunar center of mass (COM)–center of figure (COF) offset. Extant constraints on the mass asymmetr…
Recurrence Quantification Analysis of Volcanic Seismicity: Physically Interpretable Features for Multi-class Event Clas…
Volcano-tectonic (VT), long-period (LP), and hybrid (HB) events arise from distinct source mechanisms but are difficult to classify automatically due to waveform overlap and path …
Seismic Magnitude Variance Consensus Detection Framework: A Six-Criterion Approach for Identifying Critical Earthquake …
We present a six-criterion consensus framework for identifying seismically critical earthquake zones using only standard seismic catalog data. The framework combines three newly d…
1st Adiabatic Invariants and Phase Space Densities for the Jovian Electron and Proton Radiation Belts-Galileo and GIRE3…
The fluxes and phase space densities for a fixed 1 st adiabatic invariant for high energy electrons and protons provide important inputs for various scientific studies for determi…
Preliminary Assessment of PAHs in Soil Near a Coal-Fired Power Plant
Power plants emit particulate matter into the air, making them potentially significant polluters. It includes polycyclic aromatic hydrocarbons (PAHs), which are known legacy pollu…
Modeling ionospheric TEC using gradient boosting based and stacking machine learning techniques
Accurately predicting and modeling the total electron content (TEC) of the ionosphere can greatly improve the accuracy of satellite navigation and positioning and help to correct …
How Clear-Sky Spectral Overlap Shapes Radiation in Cloudy Atmospheres
Optically-thick clouds largely emit thermal radiation at their cloud top temperature across the longwave spectrum. However, the degree to which cloud top temperature dominates out…
Radiation-enhanced fission track annealing revisited and consequences for apatite thermochronometry
Apatite fission track (AFT) analyses for granitoid and metamorphic bedrock samples from the Western Superior Province (Ontario), the Churchill-Rae Province (Melville Peninsula and…
Ambiguous stability of glaciers at bed peaks
Increasing ice flux from glaciers retreating over deepening bed topography has been implicated in the recent acceleration of mass loss from the Greenland and Antarctic ice sheets.…
Hallett-Mossop rime splintering dims the Southern Ocean: New insight from global cloud-resolving simulations
In clouds containing both liquid and ice that have temperatures between -3C and -8C, liquid droplets collide with large ice crystals, freeze, and shatter, producing a plethora of …
Geomagnetic data from the GOCE satellite mission
The Gravity field and steady-state ocean circulation explorer (GOCE) is part of ESA’s Earth Explorer Program. The satellite carries magnetometers that control the activity of magn…
