A new GBP 5 million, five-year research initiative aims to tackle some of the most fundamental questions in solar physics, with a focus on the complex and dynamic processes occurring within the Sun's atmosphere. The Solar Atmospheric Modelling Suite (SAMS) project, funded by the Science and Technology Facilities Council's (STFC) new Large Award scheme, seeks to develop a next-generation modelling tool capable of simulating the Sun's atmosphere from the photosphere to the corona, capturing the intricate interactions that drive solar activity.

The Sun's behavior profoundly influences satellites, space missions, and technology on Earth, making accurate simulations of its atmospheric processes essential. SAMS aims to overcome current limitations in solar modelling by integrating cutting-edge physics and advanced computational capabilities. The project is designed to run on a wide range of computing systems, from standard laptops to the latest Exascale supercomputers.

The initiative is led by the University of Exeter, with key collaboration from the universities of Warwick, Sheffield, and Cambridge. Professor Andrew Hillier from the University of Exeter emphasized the significance of this effort, stating, "For a long time the UK was leading the way in simulating the atmosphere of the Sun, but in recent years we have been eclipsed. This project will put us right back as one of the leaders in this area."

The SAMS project will provide open-source, physics-based modelling tools, promoting widespread accessibility and usability among researchers globally. It also aims to provide critical training for early career scientists in the complex physical processes that govern the Sun's atmosphere, supporting the next generation of solar researchers.

Dr. Erwin Verwichte, Associate Professor (Reader) at the University of Warwick, highlighted the foundational role of their institution in this effort, noting, "Warwick has built a world-leading reputation in numerical modelling of plasma physics. Our simulation codes, whether applied to fusion research, the Sun, or space weather, are used by researchers across the world. The SAMS code will be built on top of that heritage and signifies a key stepping stone in simulating and expanding our knowledge of the Sun's atmosphere."

Professor Grahame Blair, STFC Executive Director of Programmes, reinforced the strategic importance of this investment, stating, "This substantial investment demonstrates our commitment to maintaining the UK's leading role in solar physics research. Understanding the complex dynamics of our Sun is vital not just for scientific advancement, but for protecting our technology infrastructure, satellite networks, power grids, and communications systems on Earth from the impacts of space weather."
