Abstract Seismic body waves provide valuable insights into the interiors of the Earth, the Moon, and Mars. By analyzing their waveform characteristics, we can effectively reveal deep seismic velocity structures and associated dynamic processes. For the Earth, incorporating various body waves helps improve the ray path coverage and therefore the ...

Abstract Hydrothermal sealing is a mechanism thought to be responsible for challenging‐to‐forecast phreatic and phreatomagmatic eruptions. To better understand this process, we present a study in which we assessed the textural, mineralogical, and physical properties (porosity, permeability, and tensile strength) of blocks of hydrothermal seal that were

Abstract Far Ultraviolet (FUV) dayglow emissions from Titan and Earth have been observed by the Cassini/Ultraviolet Imaging Spectrograph (UVIS, 2005–2017, solar cycle 23–24) and the Global‐scale Observations of the Limb and Disk (GOLD; 2018 ‐present, solar cycle 25) missions, respectively.

Dynamical Solar Wind Forecasting Using In Situ Solar Wind Speed Observations
Abstract Accurate prediction of the ambient solar wind at Earth is a key requirement for space‐weather forecasting but is limited by uncertainties in coronal boundary conditions and, to a lesser extent, heliospheric transport. We present a quantitative assessment of a solar wind forecast that uses near‐Earth in situ solar wind observations to estimate ...

A Study on the Geoeffective Event of 11 April 2022
Abstract Coronal Mass Ejections (CMEs) are the main drivers of geomagnetic storms. Studying their initial phases is important for understanding their propagation through the heliosphere and the effects they have on the Space Weather. In this work, as a case study, we investigate how SolO/Metis observations improve the accuracy in modeling a ...

The Effect of Field Line Tracing Height on Wang‐Sheeley‐Arge Solar Wind Predictions at Earth
Abstract A key component of the widely used Wang‐Sheeley‐Arge model is the tracing of magnetic field lines in the solar corona, as that largely determines the modeled open/closed field regions and in turn the predicted large‐scale solar wind structure. However, small closed field regions interspersed among the open field lines inside coronal holes (CHs)

Abstract Understanding the coupled ionosphere‐thermosphere response to extreme geomagnetic storms is essential for improving physical understanding and space weather forecasting. We investigated the May 2024 G5 geomagnetic storm using observations from ionosondes, COSMIC‐2, Swarm, and GRACE‐FO satellites, GNSS total electron content (TEC) networks, and

ABSTRACT Impact crater hydrothermal systems, formed after asteroid and comet impacts, have been proposed as promising habitats for life on early Earth and as key targets in the search for life on planetary bodies such as Mars, since they provide liquid water and active geochemical turnover.
