The 'type'-word was chosen after a discussion in this mailing list. You are right that the high/middle/low are slightly correlated to the altitude of the cloud-types, but the altitude dependents on pressure, temperature and latitude, so e.g. a middle type cloud can be found in higher altitudes than a high type cloud.

So, the word 'type' should catch anybodies eyes to read the explanatory text: high type clouds are Cirrus, Cirrostratus, Cirrocumulus ... and for those familiar with clouds, the terms 'high', 'middle' and 'low' are very common.

So, anytime I see the word 'type' in a variable name, it catches my eye -- it 
usually indicates a concept that exists but hasn't been named.  (Because there 
was *some* reason for grouping the clouds that way, right?)

In this case, I know pretty much nothing about clouds, but it looks to me like 
the concept may be altitude or height.  If that were true I would much prefer 
'high_altitude_cloud_area_fraction' and so on.  Or whatever the right concept 
is.

Dear Jonathan,

I just had a short side-discussion with Eizi, and we settled on 'type', i.e. we 
propose the standard names:

high_type_cloud_area_fraction
middle_type_cloud_area_fraction
low_type_cloud_area_fraction


As explanatory text, the one of cloud_area_fraction is a good start, and then 
an addition like:

  high type clouds are: Cirrus, Cirrostratus, Cirrocumulus
  middle type clouds are: Altostratus, Altocumulus, Nimbostratus
  low type clouds are: Stratus, Stratocumulus, Cumulus, Cumulonimbus

Best regards,

Heiko

Dear Eizi and Heiko

I think this kind of idea is good
high_genera_cloud_area_fraction:
etc.

"type" or "genera" would both be OK, but "genera" is a plural so better English
would probably be "type" (or "genus").

Cheers

Jonathan
