CROCA-3 is the 3rd workshop for the members of the "MICRO initiative" (MIcro-physics of Cosmic-Ray Observables).

This is meant to be an informal workshop that brings together researchers working on theory, phenomenology, and observations of cosmic rays. Plenty of time will be dedicated to discussions and brainstroming. The goal of the workshop is to update each other about our current work and to define common projects to be tackled in the following couple of years.

 ⚠️ NOTE: to avoid issues with the PHC Library connection system, this will be an in-person only meeting.
