  The Precision IceCube Next Generation Upgrade (PINGU) is a proposed extension
to the IceCube detector. The design of PINGU would augment the existing 86
strings with an additional 40 with the main goal of determining the neutrino
mass ordering (NMO). Preliminary studies of the NMO can start with
IceCube/DeepCore, a sub-array of more densely- packed strings in operation
since 2011. This detector has a neutrino energy threshold of roughly 10 GeV and
allows for high-statistics datasets of atmospheric neutrinos to be collected.
This data provides a unique opportunity to better understand the systematic
effects involved in making the NMO measurement by comparing the simulation
studies to real data. These proceedings will present the current status of
these studies in Monte Carlo simulations with projected DeepCore sensitivity
for the NMO.
