Hourly cosmic ray intensity measurements from the Neutron Monitor Database (NMDB) -- the worldwide network of ground-based cosmic ray detectors. Neutron monitors detect secondary neutrons produced when galactic cosmic rays interact with Earth's atmosphere. The count rate is a proxy for cosmic ray intensity at Earth and is modulated… See the full description on the dataset page: https://huggingface.co/datasets/juliensimon/neutron-monitor-cosmic-rays.
