Unified Model Variables from UFS
Unified model variables read by UPP (column 1), the name of the variable in the model NetCDF file (column 2), corresponding UPP internal name that the variable is read in as (column 3), variable dimension (column 4), whether the variable resides in the dyn (atm) or phy (sfc) NetCDF file, and relevant notes such as dependencies (column 5).
