NMDB: towards a global neutron monitor database

The real-time database for high resolution neutron monitor measurements (NMDB) is a scientific data repository funded by the European Commission for two years. Close to the end of the NMDB project, we have successfully created a repository for Cosmic Ray data from ground based neutron monitors. We have created tools to access the data and online applications that use this data, for example to calculate cosmic ray spectra, the ionisation of the atmosphere, or to give an automatic alert of a ground-level event. So far only European stations are contributing to this database. To reach the full potential of a Cosmic Ray database also stations outside Europe have to be included. NMDB is preparing workshops to discuss with international partners about their participation in a global neutron monitor database project.
