The Effect of Magnetic Field Line Topology on ICME-related GCR Modulation

The Astrophysical Journal, 2023
The large-scale magnetic structure of interplanetary coronal mass ejections (ICMEs) has been shown to affect the galactic cosmic-ray (GCR) flux measured in situ by spacecraft, causing temporary decreases known as Forbush decreases (FDs).

Opening a Window on ICME-driven GCR Modulation in the Inner Solar System

Astrophysical Journal, 2018
Abstract Interplanetary coronal mass ejections (ICMEs) often cause Forbush decreases (Fds) in the flux of galactic cosmic rays (GCRs). We investigate how a single ICME, launched from the Sun on 2014 February 12, affected GCR fluxes at Mercury, Earth, and Mars.

Energetic particles in the heliosphere and GCR modulation: Reviewing of SH-posters

Journal of Physics: Conference Series, 2013
This rapporteur paper addresses the SH poster session titled "Energetic particles in the heliosphere (solar and anomalous CRs, GCR modulation)" of the 23rd European Cosmic Ray Symposium (ECRS) and the 32nd Russian Cosmic Ray Conference (RCRC). The 65 posters presented are tentatively divided into five sections: Instruments and Methods; Solar Energetic ...

On the method of the GCR partial intensities related to the main physical processes of solar modulation

Journal of Physics: Conference Series, 2015
We discuss in more details the earlier suggested method to decompose the calculated GCR intensity into the partial intensities connected with the main physical processes (the diffusion, convection, adiabatic cooling and magnetic drift) of the solar modulation.

Manifestation of solar wind corotating interaction regions in GCR intensity variations

Solar-Terrestrial Physics, 2023
The regions of interaction between solar wind streams of different speed, known as corotating interaction regions, form an almost constantly existing structure of the inner heliosphere.

The influence of solar-modulated regional circulations and galactic cosmic rays on global cloud distribution

Scientific Reports, 2023
The influence of solar forcing and Galactic Cosmic Rays (GCR) ionization on the global distribution of clouds is investigated using 42 years ERA-5 data (1979–2020).

Heliospheric Modulation of GCR at Mid and High Latitudes

Physical Science International Journal, 2020
The variations of Galactic Cosmic Ray (GCR) as compared with the behaviour of various solar activity indices, heliospheric parameters and the geomagnetic index Ap during 1999-2015, which covers part of cycles 23 and cycle 24 have been studied.  Two sets of data were considered, consisting respectively of all days of the month and the five quietest days.

Solar modulation of GCR electrons over the 23rd solar minimum with PAMELA [PDF]

Journal of Physics: Conference Series, 2015
The satellite-borne PAMELA experiment has been continuously collecting data since 15th June 2006, when it was launched from the Baikonur cosmodrome to detect the charged component of cosmic rays over a wide energy range and with unprecedented statistics. The apparatus design is particularly suited for particle and antiparticle identification.

Fifty years of studying the GCR intensity during inversion of heliospheric magnetic fields I. Observations

Solar-Terrestrial Physics, 2023
The effects of the 22-year variation of solar magnetic fields in the galactic cosmic ray (GCR) intensity were first observed and interpreted as manifestations of inversion of the high-latitude solar magnetic field in properties of heliospheric magnetic ...
