Description
This poster presents the ongoing ISSI Team project "Beryllium-10 for Earth and Solar Tracing" (BEST), focused on refining the use of the cosmogenic isotope Beryllium-10 (¹⁰Be) as a quantitative proxy for past solar activity and space climate. Beryllium-10 is produced in the atmosphere by cosmic rays interacting with nitrogen and oxygen atoms. It is subsequently deposited and preserved in natural archives such as ice cores, marine sediments, and soils, making it a valuable tracer for reconstructing long-term variations in solar activity, geomagnetic field changes, and climatic conditions.
The project integrates high-resolution ¹⁰Be datasets with advanced atmospheric transport models to better understand the influence of atmospheric and climatic processes on ¹⁰Be deposition. This approach allows disentangling solar signals from terrestrial effects, improving the accuracy of past solar activity reconstructions and enhancing detection of extreme solar energetic particle (SEP) events.
The poster highlights the project framework, state-of-the-art models employed, and their capabilities in quantifying uncertainties and refining solar event histories. The results contribute to advancing space weather and space climate research, enabling improved risk assessments of extreme solar events and fostering interdisciplinary collaboration across solar physics, atmospheric science, and geochemistry.
