Aims: The 11-year solar cycle (Schwabe cycle) is the dominant pattern of solar magnetic activity reflecting the oscillatory dynamo mechanism in the Sun’s convection zone. Solar cycles have been directly observed since 1700, while indirect proxy dat

Intense solar activity was observed in May 2012. A notable ground level enhancement (GLE) was registered on 17 May 2012 by several space‐borne instruments as well as on ground by neutron monitors (NMs). This event is known as GLE # 71. Here, we der

A new model of cosmogenic tritium (³H) production in the atmosphere is presented. The model belongs to the CRAC (Cosmic Ray Atmospheric Cascade) family and is named as CRAC:3H. It is based on a full Monte Carlo simulation of the cosmic ray induced a

Aims: Continuous measurements of ground-based neutron monitors (NMs) form the main data source for studying high-energy high-intensity solar energetic particle (SEP) events that are called ground-level enhancements (GLEs). All available data are coll

Aims: Lunar soil and rocks are not protected by a magnetic field or an atmosphere and are continuously irradiated by energetic particles that can produce cosmogenic radioisotopes directly inside rocks at different depths depending on the particle’s

We retrieve ionization rates in the atmosphere caused by energetic electron precipitation from balloon observations in the polar atmosphere and compare them against ionization rates recommended for the Phase 6 of the Coupled Model Intercomparison Pro
