NMDB@Athens

This volume documents the papers presented at the hybrid symposium on cosmic ray studies with neutron monitors in Athens in September 2022. The contributions are dedicated to six topics: cosmic rays in the heliosphere, GLE analysis and space weather research, cosmic rays and the Earth's atmosphere, instrumentation and stability of neutron detectors, their response functions, and the data bases and catalogues of the Real-Time database for high resolution Neutron Monitor measurements (NMDB) project, which are freely accessible to a large user community.
