This is an overview of the solar modulation of cosmic rays in the heliosphere. It is a broad
topic with numerous intriguing aspects so that a research framework has to be chosen to …

This manuscript gives an up-to-date and comprehensive overview of the effects of energetic
particle precipitation (EPP) onto the whole atmosphere, from the lower thermosphere …

Aims. We studied the 27-day variations of galactic cosmic rays (GCRs) based on neutron
monitor (NM), ACE/CRIS, STEREO, and SOHO/EPHIN measurements in the solar minima …

The low-energy cosmic-ray (CR) fluxes measured by space-borne instruments are generally
considered to consist of gradually changing galactic CRs (GCRs) and short-lived solar …

A single channel cosmic ray muon detector was constructed and installed in Riyadh, central
Saudi Arabia, for studying the variations in the cosmic ray (CR) muon flux. The detector has …

Abstract Space weather effects have two links to research of energetic particles in space.
First, the direct one, connected with the interaction of high energy cosmic particles including …

We study the relationship of the 27-day variations of the galactic cosmic ray intensity with
similar variations of the solar wind velocity and the interplanetary magnetic field based on …

Cosmic rays (CR) play an important role in space weather-related studies. Their temporal
variability, both of a quasi-periodic character as well as an irregular one, has been studied …

We show that the higher range of the heliolongitudinal asymmetry of the solar wind speed in
the positive polarity period (A> 0) than in the negative polarity period (A< 0) is one of the …

During solar cycle 22, the modulation of several hundred MeV galactic cosmic rays (GCRs)
by recurrent and transient cosmic ray decreases was observed by the Ulysses spacecraft on …
