In this paper we discuss our pilot study where the NN emulation technique developed previously for computing model radiation parameterizations was applied to the part of the NCEP GFS model physics, GBPHYS, that is complementary to the radiation parameterization. The results of the study showed that not all outputs of GBPHYS are emulated uniformly well with the original approach. Significant differences between the radiation parameterizations and GBPHYS block and challenges for the NN emulation approach due to these differences are demonstrated and discussed. Several approaches that will allow us to deal with the challenges and that will be used to complement the NN emulation approach for dealing with entire model physics are also introduced.
