European Geosciences Union (EGU) is Europe’s premier geosciences union, to pursuit excellence in the Earth, planetary, and space sciences for the benefit of humanity, worldwide.
The EGU General Assembly 2024 in Vienna, Austria, April 14-19, brings together geoscientists from all over the world to one meeting covering all disciplines of the Earth, planetary, and space sciences. The EGU aims to provide a forum where scientists, especially early career researchers, can present their work and discuss their ideas with experts in all fields of geoscience. This event fosters collaboration and innovation, nurturing the next generation of scientific pioneers. It also serves as a premier platform for geoscientists worldwide to converge, exchange ideas, and showcase their research endeavors.
The EGU24 General Assembly welcomed 20,979 registered attendees, of which 18,388 made their way to Vienna from 116 countries and 2,591 joined online from 109 countries. It was a great success with 18,896 presentations given in 1,044 sessions. Thereby, 57% of the abstracts were identified as contributions from Early Career Scientists (ECS).
The EGU General Assembly reconvenes at the ACV in Vienna & online as EGU25, 27 April–2 May 2025.

Probing Small Scale Solar Wind Turbulence: Markovian Analysis and Scale Interactions from Inertial to Kinetic Regimes
Based on the data collected by the Magnetospheric Multiscale (MMS) mission’s satellites, we delve into the subject of turbulence on inertial, sub-ion, and kinetic scales. Building upon prior Markovian analysis of turbulence of the transfer of magnetic-to-magnetic field fluctuations in the near-Earth space environment [10.1093/mnras/stad2584, 10.3847/1538-4357/aca0a0], we also extend our investigation to ion velocity-to-velocity and magnetic-to-velocity cases. However, we direct our focus towards the purer statistical facet of the analysis, joint with the elements of dynamical approach. We analyze whether the transfer of increments exhibits ‘local‘ or ‘non-local‘ character, which in this context, they describe the scales involved in interactions that lead to the turbulent cascade. Additionally, we observe a global scale-invariance in relation to the Fokker-Planck equation, for a magnetic field case. Finally, we briefly discuss a potential non-parametric approach, namely a stochastic dynamical jump-diffusion model, or alternatively a multi-fractal approach, which can be useful to describe the underlying process accurately. We believe that such a comparative approach spanning diverse conditions is meaningful, as it aims to unveil any underlying universality within the statistical properties of the near-Earth solar wind space plasma at the intricate kinetic and sub-ion scales.
