Understanding the Sun's influence on Earth?s atmosphere, oceans, and land surfaces requires knowledge of solar irradiance variability from past centuries to the present-day. An improved understanding of historical solar variability leads to more credible future solar activity projections. Furthermore, various geophysical applications have different requirements for the temporal cadence, spectral range, resolution, and accuracy of the solar irradiance information. This session welcomes abstracts on recent advances in the understanding of solar irradiance variability in the past, present, and future from measurements and models. We also welcome abstracts that spotlight how continuous solar irradiance measurements drive improvements in various geophysical applications including global energy and climate assessments, the near-Earth space environment for space weather applications, and satellite navigation and mission planning in Low and Very Low Earth Orbit (LEO and VLEO).

These investigations also incorporate an increasingly diverse array of datasets and methodology, including crowd-sourced spatially distributed datasets, different kinds of visual classifications of auroral, solar, and lunar terrain images, feature identification in particle spectra, and auditory classifications of wave power spectral densities. This session focuses on the scientific motivation and outcomes of citizen science projects in the space sciences, highlighting studies that have been actively developing and using citizen science-derived datasets across heliophysics and planetary science. Along with results from citizen science investigations, presentations describing challenges and lessons learned (i.e., working with different platforms, interfacing with volunteers, tailoring tasks for accessibility while still retaining scientific usability, etc.) are welcome.

This technique is known as helioseismic far-side imaging, which enables the detection of active regions days before they rotate into view from Earth. In this talk, I will explain how far-side helioseismology works and present a direct validation using SO/PHI magnetograms of the Sun?s far side. I will then focus on our work, Combined Surface Flux Transport and Helioseismic Far-Side Active Region Model (FARM), published in Solar Physics (299, 161). In this study, collaborators and I introduce a novel method for estimating magnetic fields of far-side active regions from helioseismic measurements and incorporate the inferred magnetic fields into a surface flux transport model.

Abstract submission is open and the deadline to submit is August 5, 2026. IN019. Emulation Frameworks for Physics-Based Models: A Cross-Domain Assessment of Methodologies Emulating physics-based models is vital for maximizing the science return of next-generation instruments and enabling near-real-time digital twins, rapid discovery, and rigorous uncertainty quantification. This session seeks to showcase an assemblage of specific emulator or surrogate frameworks - whether using reduced-order physics, statistical methods, or machine learning - that are well suited for different modeling challenges such as overcoming computational bottlenecks or improving model understanding and uncertainties. We invite contributions that discuss motivations for emulator and surrogate technology and present architectures tested for specific scientific applications. We encourage sharing lessons learned, particularly regarding interactions across varying spatial, temporal, and spectral scales, adherence to physical laws, and domain-specific validation strategies. By bringing together these techniques, this session aims to map the landscape of advanced computational methods, evaluate transferability between domains, and advance our collective technical literacy of this emergent technology space.

See this summary of take-aways (https://www.ropesgray.com/en/insights/alerts/2026/06/omb-proposed-revisions-to-the-uniform-guidance-key-takeaways-for-award-recipient-organizations). If finalized as written, these changes could have serious consequences for federally funded research, including potential political interference in peer review, cancellation of active grants with limited justification, restrictions on categories of federally funded science, and limits on researchers? ability to publish and attend scientific conferences. Written responses to these proposed rule changes are invited by 13 July 2026. First, I encourage you to contact the appropriate offices at your home institutions and ask whether your institution will submit a written response. If so, give input. Institutional comments can be especially important because they represent the perspective of universities, research centers, observatories, and organizations that depend on fair, transparent, peer-reviewed federal science funding. Only one response is permitted per institution. Second, you can also submit responses as individuals. provide feedback directly through the federal public comment site (federalregister.gov) or through advocacy tools hosted by organizations such as the AGU Action Center (https://agu.quorum.us/campaign/163877/) and the Planetary Society (https://www.planetary.org/advocacy-action-center?vvsrc=%5CCampaigns%5C137770%5CRespond). Go here (https://solvecfs.org/how-to-submit-a-public-comment-on-the-proposed-federal-grant-rule/) for tips on how to write a response, key rule numbers, key parts of the rules, and what key sections would do. Finally, if one of your representatives serves on the House Science Committee, the Senate Commerce Committee, or either Appropriations Committee, please also consider contacting them directly and asking them to oppose changes that would weaken peer review, restrict scientific communication, or destabilize federally funded research. Science depends on open inquiry, independent peer review, transparent funding processes, and the ability to communicate results freely. These principles are worth defending, and this is a moment when our community?s voice matters.

We would like to invite you to submit an abstract to the Lightning Physics session. Details below. Title: AE005 - Physics of Streamers, Leaders, and the Lightning Discharge Description: Lightning is comprised of a variety of processes over a multitude of scales including the initial breakdown stage, fast streamer-based breakdown, leader steps, streamer zones, space stems and space leaders, needles, recoil leaders, return strokes, and M components. Lightning channels promote energy exchange between plasma and surrounding environment generating a plethora of impacts in the atmosphere and to society. In recent years, substantial instrumentation advances have been made in optical, radio-frequency, and energetic radiation imaging of the lightning channels' initiation, propagation, and attachment to ground structures, as well as the return stroke and the subsequent processes taking place inside its decaying channels. Additionally, during the next decade the field should see an explosive growth in the development and use of computational models of lightning and its multi-spectral emissions. We seek abstracts on natural and laboratory observations, modeling, and theoretical efforts dedicated to advancing our community's understanding of lightning physics.

Best wishes, Edwin Mierkiewicz on behalf of the session conveners ________________________________ P007: Dynamic Exospheres of Terrestrial Bodies through the Solar System Session ID: 279690 The exosphere is the only atmospheric regime ubiquitous across all terrestrial bodies. Its composition, energetics, and density provide critical insights into photochemical pathways, long-term atmospheric evolution, and surface-constituent analysis through solar-driven interactions. The exosphere also mediates space weather coupling between neutral populations and local plasma environments, including solar and stellar winds, ionospheres, and plasmaspheres. This session invites investigations of terrestrial exospheres throughout the Solar System and beyond, including exoplanets. We welcome contributions on physics-based and data-driven modeling, remote sensing using UV and visible observations, and novel inversion algorithms for retrieving density profiles. The session also encompasses experimental surface physics, such as sputtering and desorption, to inform source rates for surface-bound exospheres. In addition, we invite studies of neutral-plasma interactions, atmospheric escape, and the dependence of escape rates on orbital location and stellar activity. Presentations on current and upcoming missions dedicated to exospheric characterization are also encouraged.
