CEDAR email: Call for Abstracts: A105. Solar Irradiance in the Past, Present, and Future for Geophysical Applications

[Odele Coddington]

Dear CEDAR Community,


We invite you to submit an abstract to AGU26 Session, “A105. Solar Irradiance in the Past, Present, and Future for Geophysical Applications”.


The abstract submission deadline is Wednesday, 05 August 2026 at 23:59 EDT.

Session Description: Total solar irradiance (TSI) and solar spectral irradiance (SSI) are fundamental drivers of the Earth system. 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).

Confirmed Invited Speakers:
Dr. Greg Kopp, LASP/University of Colorado - Retrospective on Solar Irradiance Measurements and a Look Ahead
Asha Jain, MIT Aero/Astro and Harvard Law - Climate Effects of Space Debris Reentry and Regulatory Drivers of Space Debris Mitigation

Sincerely,
Odele Coddington (LASP/USA), Janet Machol (CU-CIRES and NOAA-NCEI/USA), Mustapha Meftah (LATMOS/France) and Ping Zhu (Shenzhen University/China
