Evaluate and optimize the physics potential of atmospheric neutrinos in the DUNE FD.
Our main goals will be the measurement of mass hierarchy and of the theta_23 octant. Further topics are Earth tomography with neutrino oscillations, decoherence, non-standard interactions, sterile neutrinos,  and other beyond-standard-model physics scenarios.    We will also discuss the use of atmospheric neutrinos for detector monitoring and pre-beam commissioning, and evaluate their contribution to the overall physics capabilities in an era when beam data is also available.
