Calibrating the Tropospheric Air and Ozone Mass

AGU Advances, Volume 6, Issue 3, June 2025.
Abstract We divide the atmosphere into distinct spheres based on their physical, chemical, and dynamical traits. In deriving chemical budgets and climate trends, which differ across spheres, we need clearly defined boundaries. Our primary spheres are the troposphere and stratosphere (∼99.9% by mass), and the boundary between them is the tropopause ...

Multitaper Magnitude‐Squared Coherence for Time Series With Missing Data: Understanding Oscillatory Processes Traced by Multiple Observables

Earth and Space Science, Volume 12, Issue 6, June 2025.
Abstract To explore the hypothesis of a common source of variability in two time series, observers may estimate the magnitude‐squared coherence (MSC), which is a frequency‐domain view of the cross correlation. For time series that do not have uniform observing cadence, MSC can be estimated using Welch's overlapping segment averaging.

Mechanism of Multiple Anomalies Prior to Japan Earthquakes From 2021 to 2023: Lithosphere‐Coversphere‐Atmosphere‐Ionosphere Coupling Driven by Pressure‐Stimulated Rock Current

Earth and Space Science, Volume 12, Issue 6, June 2025.
Abstract This study investigated the underlying mechanism of multiple anomalies preceding the earthquakes occurred in Japan from 2021 to 2023. Key parameters, including induced magnetic field (IMF), atmospheric electric field (AEF), and total electron content (TEC), were analyzed to explore their spatiotemporal relationships with seismic activity.

Variations in Event‐Bed Thickness‐Frequency Distributions Near Volcanic Islands: Indicators of Varied Geological Processes

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 6, June 2025.
Abstract A variety of subaerial and submarine events, including mass‐wasting and volcanism, can generate sediment gravity flows and fallout deposits that are preserved in deep‐water stratigraphic records. This study examines whether event beds with differing depositional and transport histories exhibit distinct thickness‐frequency distributions ...
