We review recent observations and modeling developments on the subject of galactic
cosmic rays through the heliosphere and in the Very Local Interstellar Medium, emphasizing …

Thanks to dedicated long-term missions like Voyager and GOES over the past 50 years,
much insight has been gained on the activity of our Sun, the solar wind, its interaction with …

The intensity of galactic cosmic rays (GCRs) is modulated by solar activity on various
timescales. In this study, we performed comprehensive numerical modeling of the solar …

Using measurements from the PAMELA and ARINA spectrometers on board the Resurs-
DK1 satellite, we have examined the 27 day intensity variations in galactic cosmic ray (GCR) …

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 …

Abstract Analysis of the variation of the potential gradient (PG) at ground level is important to
monitor the global electric circuit and the different solar and geophysical phenomena …

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 …

Recent solar conditions indicate a persistent decline in solar activity—possibly similar to the
past solar grand minima. During such periods of low solar activity, the fluxes of galactic …

Context. On scales of days, the galactic cosmic ray (GCR) flux is affected by coronal mass
ejections and corotating interaction regions (CIRs), causing so-called Forbush decreases …

Test-particle simulations are an important tool for magnetospheric and heliophysics
research. In this paper, we present the Space Plasma and Energetic Charged particle …
