Impact of Forbush Decreases and Geomagnetic Storms on the Atmospheric Ozone Profiles

open access: yesEarth and Space Science, 2023
The sensitivity of atmospheric ozone to geomagnetic storms and reduced cosmic rays' (CRs) intensity (called Forbush decrease [FD]) has been noticed for many years.

Relationship between solar activity and myocardial infarctions in Mexico City [PDF]

open access: yesGeofísica Internacional, 2000
Daily incidence of 2290 myocardial infarctions in Mexico City at the National Institute of Cardiology from 1992-1996 shows that the most prominent periodicity in the infarction rate is seven days.

Precursory Signs of Large Forbush Decreases

open access: yesSolar Physics, 2021
The study of space-weather effects and more specifically Forbush decreases of the cosmic-ray intensity depends on space and ground measurements. Very often Forbush decreases and geomagnetic storms are accompanied by pre-increases and/or pre-decreases manifested in cosmic-ray behavior, known as precursory signs.

Multipoint, high time resolution galactic cosmic ray observations associated with two interplanetary coronal mass ejections [PDF]

open access: yes, 2009
[1] Galactic cosmic rays (GCRs) play an important role in our understanding of the interplanetary medium (IPM). The causes of their short timescale variations, however, remain largely unexplored. In this paper, we compare high time resolution, multipoint

The Frequency‐Domain Characterization of Cosmic Ray Intensity Variations Before Forbush Decreases Associated With Geomagnetic Storms

open access: yesSpace Weather, 2022
Nonrecurrent geomagnetic storms caused by Coronal Mass Ejection (CME) can induce serious impacts on space‐ and ground‐based equipment. However, these nonrecurrent geomagnetic storms are hard to predict since CMEs are not periodic.

Forbush decreases and turbulence levels at CME fronts

open access: yes, 2008
We seek to estimate the average level of MHD turbulence near coronal mass ejection (CME) fronts as they propagate from the Sun to the Earth. We examine the cosmic ray data from the GRAPES-3 tracking muon telescope at Ooty, together with the data from ...

Characteristics and energy dependence of recurrent galactic cosmic-ray flux depressions and of a forbush decrease with LISA Pathfinder [PDF]

open access: yes, 2018
The final publication is available at IOS Press through http://dx.doi.org/10.3847/1538-4357/aaa774Galactic cosmic-ray (GCR) energy spectra observed in the inner heliosphere are modulated by the solar activity, the solar polarity and structures of solar ...

Investigating tensor anisotropy of cosmic rays during large-scale solar wind disturbances

open access: yesSolar-Terrestrial Physics, 2017
The observable anisotropy of cosmic rays has first been decomposed into zonal harmonics and components of vector and tensor anisotropy. We examine Forbush decreases in cosmic rays that occurred in November 2001 and November 2004.

Mini Neutron Monitors at Concordia Research Station, Central Antarctica [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2015
Two mini neutron monitors are installed at Concordia research station (Dome C, Central Antarctica, 75°06'S, 123°23'E, 3,233 m.a.s.l.). The site has unique properties ideal for cosmic ray measurements, especially for the detection of solar energetic ...
