Neutron Monitors (NM) have been in continuous operation in a global network since the International Geophysical Year (IGY) 1957/58. Their main purpose is the ground-based observation of temporal fluctuations in the low GeV part of the energy spectrum of cosmic ray particles hitting the Earth's atmosphere. The focus in the use of NM data has however significantly changed over time, from...
The Neutron Monitor DataBase (NMDB) has been created as an EU FP7 project in 2008. Since then, NMDB has grown from 12 participating institutes with 15 stations to more than 50 stations, about half of them currently provide data in real-time. While we created NMDB for the use of Cosmic Ray researchers, the data has been quickly found by and is nowadays being used in many different fields of...
