EGU2018 session on Cosmic rays

Lifton, Nathaniel A
Apologies for the short timeline and cross-posting…


Dear colleagues,

it is a pleasure to invite you to a dedicated session on


at the European Geoscience Union's General Assembly (EGU) on April, 8--13, 2018 in Vienna. Besides AGU, the EGU conference is one of the largest international meetings in geosciences.

The interdisciplinary session would allow you to broaden the impact of your research, and also to discuss open questions to which answers are to be found beyond your specific discipline.

The session brings together scientists from cosmic-ray physics on Earth, hydrology, radiation protection, cosmogenic nuclides, neutron monitors and detectors, and modeling. We aim to stimulate discussions about how researchers from related disciplines can exchange their knowledge and benefit from each other.

The session is convened by researchers in various fields who share the interest in measurement and modeling of cosmic radiation for environmental purposes: Marek Zreda (U Arizona), Nathaniel Lifton (Purdue U), Bernd Heber (U Kiel), Werner Rühm (HMGU Munich), Rafael Rosolem (U Bristol), Markus Köhli (U Heidelberg), Konstantin Herbst (U Kiel), Steffen Zacharias (UFZ Leipzig).

We are glad to announce that Dr. Tatsuhiko Sato (Japan Atomic Energy Agency) and Prof. Dr. Tibor Dunai (Uni Köln) have accepted their invitation as solicited speakers. Tatsuhiko is an expert in modeling interactions of cosmic-ray neutrons with the atmosphere, in dosimetry, and in biological impacts of cosmic radiation. Tibor is an expert in the physical impacts of cosmic radiation, covering cosmogenic nuclides as tracers as well as isotope dating.

More details of the session please find listed below. Abstract submission deadline is JANUARY 10th, 13:00 CET. Please note that abstracts submitted afterwards require direct interaction with the convener, come with additional fees, and have a strict deadline of JANUARY 18th, 13:00 CET.

We are looking forward to your contribution.
Have a happy New Year!

Cosmic rays across scales and disciplines: the new frontier in environmental research (co-organized)
Convener: Martin Schrön  
Co-Conveners: Marek Zreda , Nathaniel A. Lifton , Bernd Heber , W. Rühm , Rafael Rosolem , Markus Köhli , Konstantin Herbst , Steffen Zacharias

‘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 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: low-energy neutron sensing to measure water in reservoirs at and near the land surface, such as soils, snow pack and vegetation
- Environmental isotopes, cosmogenic nuclides: as tracers of atmospheric circulation and mixing; as a tool in 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
