comment:
Note on CF Conventions.
We deliberately make the following exceptions:
- the datetime data type is a 64 bit integer instead of a floating point number
- we use 'composed' CF standard names such as 'mole_fraction_of_nitrous_oxide_in_air_standard_error' (the '_standard_error' suffix makes this not a CF standard_name in a strict sense)
- some units aren't UDUNITS-compliant (such as '1/cm^3_STP' for number per cubic centimeter at standard temperature and pressure
