This session seeks contributions on the current system in geospace, its drivers, dynamics, and coupling, using observations, models, and their combinations to connect different AGU sections' perspectives. The full session description is attached for your reference.

The abstract deadline is Wednesday, 30 July 2025 23:59 EDT/03:59 UTC We are looking forward to seeing your abstract. Feel free to contact us at with any questions. Sincerely, The session conveners Astrid Maute, Toshi Nishimura, Patrick Alken, Karl Laundal, Sneha Yadav SA010: Current System throughout Geospace: Its Drivers, Dynamics, and Coupling Currents in the magnetosphere interact dynamically with the ionosphere, varying significantly in space and time, especially during strong solar wind driving. Ionospheric currents provide insights into the magnetosphere. A simple picture of field-aligned currents closing at high latitudes exists. The low and mid-latitude current system is illustrated by a solar quiet (Sq) current system connected by interhemispheric field-aligned current and the equatorial electrojet. However, the reality is more complex with currents connecting globally and varying in 3D. These complexities are not fully understood, even though these currents play a significant role in the energetics through energetic precipitating particles, ion-neutral coupling, momentum exchange, and the ionospheric electrodynamo. Direct current measurements are challenging, often inferred from magnetic perturbations at ground or LEO altitudes and local rocket measurements. This session seeks contributions on the current system, its drivers, dynamics, and coupling, using observations, models, and their combinations to connect different AGU section's perspectives. -------------- next part -------------- An HTML attachment was scrubbed...

The AGU meeting will be held 15-19 Dec 2025 in New Orleans, LA. The abstract deadline is Wednesday, 30 July 2025 23:59 ET/03:59 UTC Our session is described at: https://agu.confex.com/agu/agu25/prelim.cgi/Session/250850 The international sunspot number (SN) is the recalibration of the Z?rich sunspot number (RZ) that is currently measured and served at the WDC SILSO. This modernization provides a consistent extension of the most analyzed solar-variability observational time series available. After the recalibration that culminated in 2015, the current reconstruction includes a re-examination of the sources underlying SN and means of connecting different observational records. The working group responsible for SN is accumulating original drawings and searching for sources of data particularly during the various temporal gaps in coverage. This research improves the historical record especially before 1825. The goal of this session is to focus on ways to continue updating the observer-record calibrations and the temporal coverage of SN, and to assess future needs. This covers a wide range of subjects such as: Should the cadence of the released data be increased, such as from the current one day to one hour? Can AI/ML algorithms ingest the hand-drawn images from the 1600s to the 1800s and help fill in gaps? Works describing how SN can be improved to match the user needs or ways to implement SN in modern algorithms are solicited.

Previous NWC Workshops were held in Kyoto (1994), Cologne (1997), Carlsbad Calif. (1999), Tromso (2001), Mumbai (2003), Fukuoka (2006), Beaulieu-sur-Mer (2008), and La Jolla Calif. (2010, 2013, 2017). The workshop is aimed to be a highly interactive, friendly, informal get-together of scientists from different fields of expertise discussing common workshop topics with highlights on (1) nonlinear waves, (2) chaos, and (3) nonlinear physics using AI. Past attendees of NWCWs have included experts in plasma physics (space and astrophysical plasmas, laboratory plasmas, and fusion plasmas), geophysics (atmospheric, ionospheric, and oceanic turbulence), fluid dynamics, nonlinear physics, and mathematics. All speakers will be allowed an equal amount of time for their talks. All talks can be interrupted by questions from the audience. Such interactions are encouraged since this event will have a workshop format (unless the discussions are too extensive). We arrange for a book as an outlet for the writeup of the talks. We expect all presentations to be written up and submitted for this publication. There will be an upper limit of 30 attendees so that the workshop format will be effective. For this reason, the attendance is by invitation only. If you are expert in one of the three topics and would like to attend, please contact one of the 5 Convenors.

The forcing of these regions and the many different processes involved vary over a wide range of spatial and temporal scales, hindering accurate determination of these fundamental parameters critical to satellite operations and radio communications. Past and current space missions, field campaigns, as well as theoretical and modeling advances, have led to a new understanding of how and why the dominant drivers of upper atmospheric composition, winds, and temperatures in these regions change over different spatial and temporal scales. This session, therefore, seeks to highlight various topics surrounding middle and upper atmospheric composition, wind, and temperature measurements, their variability, and the prominent mechanisms that drive their spatial, seasonal, and inter-annual variability from theoretical, observational, and modeling perspectives. We look forward to your contribution to our AGU25 session. Please note that the abstract submission deadline is *Wednesday, 30 July 2025 at 23:59 EDT/03:59 UTC*. Thank you.

This session explores the relative roles and interactions of atmospheric waves?such as tides, planetary waves, and gravity waves?and external drivers, including solar irradiance, solar wind, and geomagnetic activity, in shaping global ITM variability. Special emphasis is placed on disturbances from sudden stratospheric warmings, volcanic eruptions, tropospheric convection, and geomagnetic storms. We invite observational, theoretical, and modeling studies that investigate coupling across spatial and temporal scales, with contributions from satellite missions (e.g., ICON, GOLD, AWE, COSMIC-2, MMS), ground-based networks (e.g., SuperDARN, GNSS, ISR, Fabry-Perot interferometers, magnetometer arrays), and advanced models (e.g., WACCM-X, MAGE, TIEGCM, SAMI3). This session encourages cross-disciplinary collaboration to improve understanding of whole-atmosphere coupling and its impact on space weather, electrodynamics, and thermospheric structure. We look forward to your contribution to our AGU25 session. Please note that the abstract submission deadline is Wednesday, 30 July 2025 at 23:59 EDT/03:59 UTC.

Anderson University of Texas at Dallas Conveners Douglas E. Rowland NASA Goddard Space Flight Center Jeffrey P Thayer University of Colorado Boulder Eftyhia Zesta NASA Goddard Space Flight Center Session Description: It is becoming increasingly obvious that multi-satellite constellations are needed to take the next step in understanding the near-Earth environment and associated disturbances. Satellite constellations can separate the spatial and temporal features of space plasmas and neutrals at diverse spatial and temporal scales. Results from the AMPERE, Swarm, and ST5 constellations have provided insight on the spatiotemporal characteristics of field-aligned currents. DMSP has provided a multi-decade dataset of measurements of ionospheric properties, and current and upcoming missions including EZIE and TRACERS are expected to provide new datasets for focused electrodynamics problems. GDC is the first planned constellation providing simultaneous measurements of auroral/ionospheric and thermospheric characteristics and studies using both real and simulated data from multi-satellite constellations will offer useful information for planning. We invite presentations on this subject using observations from existing/former satellite constellations, modeling, and ground-based observatories covering the auroral ionosphere including connections to the magnetosphere and neutral atmosphere We look forward to your contributions to our session.

Description of the Session: ?The exosphere is the only atmospheric layer ubiquitous in all terrestrial bodies. Their composition, energy, and density distribution can provide important insight into atmospheric photochemistry (Venus), atmospheric evolution timeline (Earth, Mars, Venus, Titan), surface composition via interactions with the Sun (Mercury, Earth and Jovian's moons), and space weather effects through coupling with the solar wind and the local plasma environment (Jovian moons, Earth, Mars, Titan). This session focuses on investigations of exospheres of terrestrial bodies throughout the solar system and other stellar systems (exoplanets). Topics for this session include physics- and data-based modeling of exospheres, remote sensing techniques including space- and ground-based UV and visible light observations, inversion methods to retrieve density distributions, the interaction of the neutral exospheres with local plasma population (solar/stellar wind, plasmasphere, ionospheres), estimations of atmospheric escape rates (due to planetary orbital location and solar/stellar activity), and presentations of current/upcoming missions aimed for exospheric observations. Student and early-career contributions are especially encouraged!

Session description: Recent advances in modeling and computational techniques have helped improve our understanding of the global dynamics of the atmosphere and advanced our knowledge of and ability to make accurate system-level predictions. In general, the short-term variability of the atmospheric system, including its coupling to the ionosphere, continues to be one of the biggest challenges for the community. This is because the atmosphere is sensitive to internal and external inputs that are heavily affected by transient phenomena. In this session, we invite contributions related to atmospheric responses to transient events such as solar eclipses, anthropogenic explosions, hurricanes, tsunamis, earthquakes, volcanic eruptions, etc. Authors of experimental/observational investigations and theoretical/simulation are encouraged to submit abstracts and use this space to share experiences and enrich the scientific discussion.

Session description: This session focuses on natural and artificial sources of heavy metals in the mesosphere and lower ionosphere altitudes using in-situ and ground-based measurement techniques. Along with the ongoing meteoritic metal deposition, the increase in satellite deployments and subsequent deorbit burnup introduces additional heavy metals and other constituents into the mesosphere and lower ionosphere. These changing densities could affect chemical processes, energy transfer and emissions, climate evolution, and other atmospheric dynamics. Factors revealed by this research may be necessary for accurate data analysis and future mission planning.

More details about this session can be found here with a button to directly submit your abstract: https://agu.confex.com/agu/agu25/prelim.cgi/Session/249054. Please don't hesitate to reach out if you have any questions (Dong Lin, ldong.aurora at gmail.com); Session description: Auroral precipitation are magnetospheric particles that are lost in the upper atmosphere. It is one of the most well-known and yet poorly understood phenomena in space physics. Various physical mechanisms can drive particle precipitation resulting in distinct energy spectra, spatial distribution, and variability with solar wind conditions and geomagnetic activity levels. Auroral precipitation is an important ionization source in the ionosphere-thermosphere (I-T) system and changes the upper atmospheric states and high-latitude ionospheric conductivity, which impacts magnetosphere-ionosphere-thermosphere (MIT) coupling processes such as plasma convection, current system, ion drag and Joule heating. Recent advances in observational and computational capacities have enabled novel understanding and quantification of auroral precipitation and its impact on MIT coupling and global I-T dynamics. We welcome presentations on advances and/or challenges in the driving mechanisms and characteristics of auroral precipitation, and its regional and global effects in the MIT system using observations and/or models.
