几十年来，全球中子监测网已成功地用于研究宇宙射线的变化和高能太阳粒子的通量。如今，它还用于空间气象目的，例如辐射照射警报和评估。在这里，我们介绍了全球中子监测网络的现状。我们讨论了全球中子监测网络研究太阳高能粒子的能力，特别是在大的地面增强。作为一个例子，我们证明了在地面水平增强GLE #5和由此产生的有效剂量超过地球仪在一个典型的商业喷气式飞机飞行高度为40千英尺（12,200米）以上的海平面上的太阳质子特性。我们提出了一项改进空间气象服务和全球中子监测器网络应用的计划，特别是与太阳高能粒子有关的研究，即用几个新的监测器扩展现有网络。我们讨论了优化的全球中子监测网络的能力，研究各种人口的太阳高能粒子，并提供可靠的空间气象服务。
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 for space weather purposes, e.g. alerts and assessment of the exposure to radiation. Here, we present the current status of the global neutron monitor network. We discuss the ability of the global neutron monitor network to study solar energetic particles, specifically during large ground level enhancements. We demonstrate as an example, the derived solar proton characteristics during ground level enhancements GLE #5 and the resulting effective dose over the globe at a typical commercial jet flight altitude of 40 kft (≈12,200 m) above sea level. We present a plan for improvement of space weather services and applications of the global neutron monitor network, specifically for studies related to solar energetic particles, namely an extension of the existing network with several new monitors. 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.
