This may be a good case for tag. Thinking about a instrument RH tag which has at least two values (e.g., Dry and NotDryEnough) to indicate if the sample were...

I consulted with a well-known aerosol measurement expert, Luke Ziemba:

Optical depth within each cloud layer - a component of cloud optical depth which results from a vertical integral of light extinction by cloud particles between the observed bottom and...

To me, this is proposal is not ready. @fstuerzl, do you agree? After looking into "hydrometeors" more, we may want to leave it and add descriptions.

Propose to adopt or modify the AMS hydrometeor definition: "Any product of condensation or deposition of atmospheric water vapor, whether formed in the free atmosphere or at the earth's surface,...

@charlesabrock and @markusfiebig: how would you define "cloud hydrometeor"? This term has been used in code 182 (Cloud hydrometeor concentration) and code 183 (Effective radius of cloud hydrometeors), which started...

proposed description for Cloud hydrometeor concentration (182) and Effective radius of cloud hydrometeors (183): Cloud hydrometeor concentration: number of cloud hydrometeors (or cloud particles) per unit volume. Cloud hydrometeors refer...

I consulted a cirrus cloud expert myself and learned "effective radius" have had more than one definition. However, they are all some kind of weighted mean. https://journals.ametsoc.org/view/journals/clim/11/7/1520-0442_1998_011_1793_teriic_2.0.co_2.xml

We need a systematic approach for the aerosol variables. It is not practical to add modifiers to the variable names. Are we allowed to add attributes or variable descriptions? Fundamentally....
