The Effect of Forbush Decreases on the Polar-Night HOx Concentration Affecting Stratospheric Ozone

Frontiers in Earth Science, 2021
It is well-known that energetic particle precipitations during solar proton events increase ionization rates in the middle atmosphere enhancing the production of hydrogen oxide radicals (HOx) involved in the catalytic ozone destruction cycle.

The Amerigo Vespucci as a traveling laboratory for studying the cosmic-ray fluxes at sea level [PDF]

Scientific Reports
We have installed and operated a plastic scintillator detector counter to measure the flux of cosmic radiation during the 2023−2025 tour of the historical vessel Amerigo Vespucci.

The amplitude and phase distributions of cosmic ray variation at different conditions of Forbush decrease

Results in Physics, 2022
The Forbush effect is one of the striking examples of irregular variations in the cosmic ray (CR) flux. It is a heliospheric phenomenon that includes a decrease and a recovery of the CR intensity and small changes in the CR density and anisotropy before ...

Forbush Effects Associated with Disappeared Solar Filaments

Atmosphere
The Forbush effects (FEs) in cosmic rays associated with interplanetary disturbances caused by the disappearance of solar filaments (DSFs) outside active regions (ARs) are considered.

Forbush-storm classification of the events as a device for the solar wind diagnostics [PDF]

E3S Web of Conferences, 2020
The geoeffectiveness of the solar wind is usually determined on Earth by such phenomena in the geomagnetic field as storms and substorms. The second, no less significant effect is a sharp decrease in the intensity of galactic cosmic rays (GCR) Forbush ...

Letter to the Editor
Forbush precursory increase and shock-associated particles on 20 October 1989 [PDF]

Annales Geophysicae, 2002
Strong interplanetary disturbances may affect cosmic ray protons tremendously with energies less than 1 GeV, increasing their intensity by hundreds of percents, but they are not so effective for protons of higher energies.

Effects of Forbush Decreases on Clouds as determined from PATMOS-x

Journal of Atmospheric and Solar-Terrestrial Physics, 2022
<p>This study examines the relationship between cosmic rays and clouds during Forbush decreases (FDs) to understand the cause-effect relationships between cloud microphysics, cloud condensation nuclei (CCN), and ionisation in the atmosphere.

Low Latitude Lightning Activity Responses to Cosmic Ray Forbush Decreases

Geophysical Research Letters, 2020
The relation between low latitude lightning activity and Forbush decreases (FDs) of galactic cosmic rays was studied, with flash rates observed by the Lightning Image Sensor aboard the Tropical Rainfall Measuring Mission satellite and FDs selected from ...

Characterizing Interplanetary Coronal Mass Ejection-related Forbush Decreases at Mercury Using MESSENGER Observations: Identification of a One- or Two-step Structure

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

Ionization effect of solar particle GLE events in low and\ middle atmosphere [PDF]

Atmospheric Chemistry and Physics, 2011
Using a new reconstruction of the solar proton energy spectra for Ground Level Enhancement (GLE) events, based on fits to measurements from ground-based and satellite-borne instruments covering a wide energy range, we quantitatively evaluate the possible
