NMDB: the Neutron Monitor Database

Real-Time Database for high-resolution Neutron Monitor measurements

one stop shop for cosmic ray data

NMDB provides access to Neutron Monitor measurements from stations around the world. The goal of NMDB is to provide easy access to all Neutron Monitor measurements through an easy to use interface. NMDB provides access to real-time as well as historical data.

NMDB distributes official data provided by the PIs of the neutron monitor stations. Data of different origin may not have been validated or authorised by the respective PI, and any deviation with respect to the authorised data is not his/her responsibility.

Data retrieved via NMDB are the property of the individual data providers. These data are free for non commercial use within the restrictions imposed by the providers. If you use such data for your research or applications, please acknowledge the origin by a sentence like “We acknowledge the NMDB database www.nmdb.eu, founded under the European Union's FP7 programme (contract no. 213007) for providing data.", and acknowledge individual monitors following the information given on the respective station information page (see sub-pages under www.nmdb.eu).
