“…This study is a continuation of the previous proposition for optimization of the global NM network [24]. Here, we would like to stress that even a partial reduction of the number of existing NMs would considerably influence the capability of the global NM network GLEs registration and the corresponding space weather services [25]. Nowadays, the existence and continuous functioning of several NM stations is questioned, therefore, the support of the network from governments, foundations(s) and space flight operators is crucially needed.…”

Over several decades, the global neutron monitor network was extensively and with undoubtful success used to study cosmic ray variations and fluxes of accelerated solar ions, the latter known as solar energetic particles. Recently, it has been used also for space weather purposes, specifically for alerts, and to provide crucial information necessary for assessment of different space weather effects, specifically the assessment of the exposure to radiation at flight altitudes. Here, we discuss the current status and applications of the global neutron monitor network, precisely its capability to study solar energetic particles, namely assessment of their spectral and angular distribution, during strong solar proton events e.g. those leading to ground level enhancements. Several examples are presented, accordingly. We also discuss the existing gaps in the network and propose an improvement of the network, namely a plan for an extension of the existing network with several new stations, in order to provide a more accurate analysis of strong solar proton events and to respond to the current space weather demands and services. We discuss the ability of the optimized global neutron monitor network to study various populations of solar energetic particles and to provide reliable space weather services.

“…For reliable analysis of NM records it is necessary to possess enough NM stations [10]. The methods for an analysis of GLEs using NM data are based on modeling of the global NM network response and unfolding 𝑛 model parameters over the experimental records of 𝑚 NMs [11,12].…”

The first solar proton event of solar cycle 25 was detected on 28 October 2021 by several neutron monitors (NMs) in the polar region; the strongest signal was registered by the DOMC/DOMB monitors located at the Antarctic plateau at Concordia French-Italian research station, as well as the fleet of space-borne instruments. It is identified as the GLE (ground-level enhancement) # 73 in the International GLE database. Here, we report the observations and the study of this event on the basis of the global NM network and SOHO/ERNE records. We present the derived angular and spectral features of solar energetic protons, including their dynamical evolution throughout the event employing a state-of-the-art model based on analysis of the neutron monitor data. We discuss the origin of the prompt and delayed components of the GLE-inducing solar protons. Several applications of the derived results are discussed.

Over the years the global neutron monitor network was successfully used to study cosmic ray variations and fluxes of accelerated solar ions, known as energetic solar particles. Recently, it has been used also for space weather purposes, specifically alerts and as a proxy to the related assessment of exposure to radiation (dose). Here, we overview the current status and applications of the global neutron monitor network and discuss its capability to study solar energetic particles, namely assessment of their spectral and angular distribution, during ground-level enhancements, focusing specifically on polar neutron monitors. Here we propose to build several new polar neutron monitor (NM) stations in order to optimize the capability of spaceship Earth to register and provide reliable data for analysis of strong solar energetic particle (SEP) events. We propose to rebuild or open new stations in both North and South hemispheres, e.g. Alert ALRT,
