The SCM and the UFS Atmosphere access runtime configurations from file input.nml
. This file contains various namelists records that control aspects of the I/O, dynamics, physics etc. Most physics-related options are in reords &gfs_physics_nml and &cires_ugwp_nml. When using the GFDL microphysics scheme, variables in namelist &gfdl_cloud_microphysics_nml are also used. Additional specifications for stochastic physics are in namelists &stochy_nam and &nam_sfcperts.
