I agree with you - thanks for this.

Regarding the definition of rain and cloud liquid water,
I should have been more careful about whether it is established
or not, since I'm not certain about it - I'm sorry for this.
I just wanted to mention the description in the Glossary
of Meteorology of American Meteorological Society.
It may not be part of CF yet.

raindrop
  A drop of water of diameter greater than 0.2 (or 0.5)mm
   falling through the atmosphere.

cloud drop
  A spherical particle of liquid water, from a few
  micrometers to a few tens of micrometers diameter.
  A diameter of 0.2mm has been suggested as an upper
  limit to the size of drops.

Best wishes,

Tomoo
