Note	common unit is g/kg even though this would be dimensionless, entry in cf-conventions list: 'humidity_mixing_ratio' (Humidity mixing ratio of a parcel of moist air is the ratio of the mass of water vapor to the mass of dry air) is a good description, but the expressing humidity mixing ratio' is hardly in use
