'Cosmic rays’ collectively describe particles that bombard the Earth from space. They carry information about space and, once near the Earth, interact with the magnetosphere, atmosphere, hydrosphere and lithosphere. Secondary cosmic rays created within the atmosphere can provide information about our planet that is vital to science and society. Secondary neutron radiation plays an extraordinary role, as it not only carries information about solar activity, but also produces short and long living tracer isotopes, influences genetic information of living organisms, and is extraordinarily sensitive to hydrogen and therefore also to water. Given the vast spectrum of interactions of cosmic rays with matter in different parts of the Earth, cosmic-ray research ranges from studies of the solar system to the history of the Earth, and from health and security issues to hydrology and climate change.

Although research on cosmic-ray particles is connected to a variety of disciplines and applications, they all share similar questions and problems regarding the physics of detection, modeling, and environmental factors that influence the intensity. Questions that all disciplines have in common are, for example, “How does the cosmic-ray intensity and energy spectra change with time and location on Earth?”, “How to correct the signal for magnetospheric or atmospheric fluctuations?”, “What is the influence of local structures, water bodies, and surface conditions?”, “Which computer model for cosmic-ray propagation is correct?”, or “What can we learn from other types of cosmic-ray particles?”.

The session brings together scientists from all fields of research that are related to monitoring and modeling of cosmogenic radiation. It will allow sharing of expertise amongst international researchers as well as showcase recent advancements in their field. The session aims to stimulate discussions about how individual disciplines can share their knowledge and benefit from each other.

We solicit contributions related but not limited to:
- Health, security, and radiation protection: cosmic-ray dosimetry on Earth and its dependence on environmental and atmospheric factors
- Planetary space science: satellite and ground-based neutron and gamma-ray sensors to detect water and soil chemistry
- Neutron monitor research: detection of high-energy cosmic rays variations and its dependence on local and atmospheric factors
- Hydrology and climate change: low-energy neutron sensing to measure water in reservoirs at and near the land surface, such as soils, snow pack and vegetation
- Cosmogenic nuclides: as tracers of atmospheric circulation and mixing; as a tool in archaeology or glaciology for dating of ice and measuring ablation rates; and as a tool for surface exposure dating and measuring rates of surficial geological processes
- Detector design: technological advancements for the detection of cosmic rays
- Cosmic-ray modeling: advances in modeling of the cosmic-ray propagation through the magnetosphere and atmosphere, and their response to the Earth’s surface
- Impact modeling: How can cosmic-ray monitoring support environmental models, weather and climate forecasting, irrigation management, and the assessment of natural hazards
