Dear Bruce, Heiko et al.

> 1. Cloud Height Classification Based on Cloud Types

> low_type_cloud_area_fraction
> medium_type_cloud_area_fraction
> high_type_cloud_area_fraction

I continue to think these are fine. They are names of cloud genera, as earlier
discussed.

I think the problem with names based on height ranges is that they are not
well-defined, as you and Heiko say, so it would be necessary to include a
coordinate to define the range. But if you do that, the low/medium/high is
not needed, and in fact unhelpful because it is restrictive. You only need the
one (existing) standard_name of cloud_area_fraction if you give a height range,
and it should be possible to give a height range if the quantities come from
analysis of numerical datasets.

Best wishes

Jonathan
