I will give an overview over key aspects of geodynamic numerical modelling of the solid Earth following our review paper (van Zelst et al. 2022) and the annual EGU short course titled “Geodynamics 101: Numerical modelling”. Numerical modelling aims to gain scientific understanding of a certain real-Earth observation. It consists of a physical and numerical model, a numerical code, a specific...

Hyper-Kamiokande is a next-generation neutrino experiment that is under construction in Japan. Among its various physics goals, it will be used to make long-baseline neutrino oscillation measurements. This will combine neutrinos from the J-PARC accelerator (which is now serving the T2K experiment) as well as neutrinos created by interactions of primary cosmic rays from the atmosphere. The...

The Jiangmen Underground Neutrino Observatory (JUNO) is a next-generation neutrino detector under construction in Guangdong, China. With a 20-kt target, JUNO will be the largest liquid scintillator (LS) detector ever built. JUNO’s instrumental setup includes nearly 18,000 20-inch photomultiplier tubes, providing an extensive 78% optical coverage.
The primary objective of JUNO is to...

The KM3NeT Collaboration is incrementally building a network of water-Cherenkov neutrino observatories in the Mediterranean Sea, consisting of two telescopes, named ARCA and ORCA (respectively for Astroparticle and Oscillation Research with Cosmics in the Abyss), sharing the same detection technology. Owing to the different energy ranges covered by its two detectors, KM3NeT will perform both...

The information about the internal structure of Earth is obtained mainly using seismic studies and gravitational measurements. Neutrinos can be used as an independent probe to explore the interiors of Earth. While passing through Earth, the upward-going atmospheric neutrinos with multi-GeV energies experience matter effects due to the coherent forward scattering with the ambient...

Constraints on the 3-D density structure of Earth’s mantle provide important insights into the nature of seismically observed features, such as the Large Low Shear Velocity Provinces (LLSVPs) in the lower mantle under Africa and the Pacific. The only seismic data directly sensitive to density variations at all depths inside the mantle are long-period normal modes: whole Earth oscillations that...
