Forbush decreases: Algorithm generated dataset [PDF]
Data in Brief, 2020 Efforts to correctly detect Forbush decreases (FDs) in the cosmic ray (CR) intensity flux are ongoing (see [2,7]). The FD data presented here are a part of the data generated in [6] in a recent investigation of the effects of CR anisotropies on the ...

Revisiting two-step Forbush decreases [PDF]
Journal of Geophysical Research: Space Physics, 2011 Interplanetary coronal mass ejections (ICMEs) and their shocks can sweep out galactic cosmic rays (GCRs), thus creating Forbush decreases (FDs). The traditional model of FDs predicts that an ICME and its shock decrease the GCR intensity in a two-step ...

Model of optical response of marine aerosols to Forbush decreases [PDF]
Atmospheric Chemistry and Physics, 2010 In order to elucidate the effect of galactic cosmic rays on cloud formation, we investigate the optical response of marine aerosols to Forbush decreases – abrupt decreases in galactic cosmic rays – by means of modeling. We vary the nucleation rate of new

Earth and Planetary Physics, 2020 Forbush decreases are depressions in the galactic cosmic rays (GCRs) that are caused primarily by modulations of interplanetary coronal mass ejections (ICMEs) but also occasionally by stream/corotating interaction regions (SIRs/CIRs).

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.

Space weather and dangerous phenomena on the Earth: principles of great geomagnetic storms forcasting by online cosmic ray data [PDF]
Annales Geophysicae, 2005 According to NOAA space weather scales, geomagnetic storms of scales G5 (3-h index of geomagnetic activity Kp=9), G4 (Kp=8) and G3 (Kp=7) are dangerous for satellites, aircrafts, and even for technology on the ground (influence on power systems, on ...
