A network of cosmic ray muon detectors can provide real-time monitoring of space weather conditions. By deploying detectors in different geographical locations, the network can capture spatial variations and provide a more comprehensive view of the space weather environment in complementary with cosmic ray neutron measurements, geomagnetic observations, and space-base satellites, etc.
One of the major challenges in building a network of cosmic ray muon detectors is the deployment of efficient and affordable detectors capable of providing the sensitivity accurately to the variations of both space and terrestrial weather patterns. To address this challenge, a low-cost and portable muon particle detector has been developed at Georgia State University. In this presentation, we will discuss the correlation analysis of cosmic muon flux variations with Earth’s atmospheric parameters as well as their sensitivity to solar activities and geomagnetic disturbances. The muon flux measurements utilized in this analysis were obtained from a cosmic ray muon detector installed at Mount Wilson Observatory, California, in June 2022. The findings from this study have the potential to contribute to the better understanding of the interactions between cosmic rays and atmospheric conditions. Furthermore, the portable and low-cost nature of the muon particle detector developed at Georgia State University opens up possibilities for widespread deployment, facilitating extensive data collection and analysis in various geographical locations.
