TDM4 - Observations of transient events with the global neutron monitor network: Topical Discussion Meeting

Description
Over several decades the global neutron monitor (NM) network provides continuous records of cosmic ray (CR) variations. NMs have been extensively used as the main global multi-instrument tool for the analysis of a specific class of strong solar particle events, namely ground level enhancements (GLEs) in which solar ions are accelerated to quasi and relativistic energies, leading to sudden increases of count rates of particle detectors at the surface of the Earth. GLEs are particularly strong SEP events with imminent space weather effects. In addition, NMs are used for the registration of Forbush decreases and recently observed anisotropic CR enhancements (ACREs). 2024 was a particularly interesting year with three GLEs, a notable Forbush decrease and ACRE reported.
The purpose of this meeting is to discuss the applications of the global NM network for space-weather purposes, including alerts for GLEs, aircrew dose assessment and monitoring services. The session is devoted to recent works related to all aspects of space weather, focusing on the application of NMs for study transients and the related space weather phenomena. Special focus will be given to recent advances of modeling of transients, nowcasting of aircrew dose exposure, specifically during GLEs. The applications of the global NM network measurements and outputs within satellite-born instruments, as well as, other ground based detectors, which provide complementary information to NM records and can be used to unfold open issues as e.g. spectra evolution during GLEs are relevant to this session.
