This paper presents a review on the PECASUS service, which provides advisories on
enhanced space weather activity for civil aviation. The advisories are tailored according to …

We present a new open‐source tool for magnetospheric computations, that is modeling of
cosmic ray (CR) propagation in the geomagnetosphere, named “Oulu—Open‐source …

The global neutron monitor network has been successfully used over several decades to
study cosmic ray variations and fluxes of energetic solar particles. Nowadays, it is used also …

Significant increases to the atmospheric radiation environment are recorded by a network of
ground level neutron monitors as ground level enhancements (GLEs). These space weather …

A ground-level enhancement (GLE) event is a sudden increase in cosmic ray intensity
originated by solar sources and recorded by ground-based detectors. GLEs are invariably …

Fluxes of solar energetic particles (SEPs), produced and accelerated in and in the vicinity of
the Sun, are an important part of cosmic ray induced terrestrial effects such as ionizing …

In recent years, there has been a huge increase in air travel, both for business and leisure.
For this reason, entities such as the European Commission and the International Committee …

Interplanetary scintillation (IPS) is a useful tool for detecting coronal mass ejections (CMEs)
throughout interplanetary space. Global magnetohydrodynamic (MHD) simulations of the …

In recent decades, the exposure of aviation crews and passengers to cosmic radiation has
been progressively increasing due to the growing need of flights. Therefore, there is a need …

Traveling Ionospheric Disturbances (TIDs) reflect changes in the ionospheric electron
density which are caused by atmospheric gravity waves. These changes in the electron …
