-The **Units** columns gives the internal model units, and therefore those required by the NetCDF and constants namelist. "dt" is the length of the model timestep, for example, is the model has a timestep of one day, then "kg/timestep" means "kg/day". The NanoFASE data module is capable of converting units of spatial data (not constants), and therefore any reasonable units can be used for the data input to this - as long as these units are specified in the config file.
