Future of Atmospheric Neutrino Measurements

Discovery of large θ13 has opened up the possibility of determining the neutrino mass hierarchy and θ23 octant through earth matter effects. The atmospheric neutrinos pick up large earth matter effects both in the νe and νμ channels, which if observed could lead to the determination of the mass hierarchy and θ23 octant using this class of experiments in the near future. In this talk I review the status and prospects of future atmospheric neutrino measurements in determining the mass hierarchy and octant of θ23.
