Space weather and modulation processes inside the Heliosphere

• Cosmic rays (CRs) of both galactic (GCRs) and solar (SCRs) origin
• Modulation of GCRs by the heliospheric magnetic field
• Solar Flares and Energetic Particle (SEP) Events – analysis and interpretation using observations by, e.g., GOES
• Large scale structures (Interplanetary Coronal Mass Ejections – ICMEs) their interaction with GCRs and the resulting Forbush decreases (FDs)
• Exploring the connection chain of ICMEs, FDs and Geomagnetic effects/storms.

Space weather and it’s impact on Venus, Earth, and Mars

• Reconstruction of the solar activity of thousands of years and investigation of potential solar super events based on numeric modeling of cosmogenic radionuclides (e.g., ¹⁰Be, ¹⁴C and ³⁶Cl)
• Impact of Ground Level Enhancement (GLE) events on the Venusian, Martian and Terrestrial atmosphere wrt atmospheric ionization and radiation dose, and thus chanhes to the atmospheric chemistry and planetary habitability
