Hi Steve,

I'm afraid I don't understand your comment. When I search for "fraction" in the 
NIST document I find it defined as being a ratio, which is inconsistent with 
the current CF usage. The CF standard name concept "area_fraction" is not what 
NIST or others understand as a "fraction". I'm suggesting a change to remove 
this inconsistency,


regards,

Martin

Could we avoid this confusion in the future by replacing the term with a more

That would be inconsistent with the NIST recommendation. See 
<https://www.nist.gov/physical-measurement-laboratory/nist-guide-si-chapter-8>. 
Search for "fraction".
