    <p>Martin,</p>
    <p>The height scalar variable you are referring to is numeric,
      right? It may not be a coordinate variable in the pure NUG sense,
      but CF isn't bound by exact adherence to NUG if it defines its
      terms, and David has posted the relevant sections from the
      Conventions. It is clear to me that those sections declare that a
      numeric scalar variable may serve as a valid 'true' coordinate
      variable, <i>as opposed to</i> an auxiliary coordinate variable.
      The mechanism for relating a scalar coordinate variable to a data
      variable is through the 'coordinates' attribute, but that does not
      force it to be considered to be an auxiliary coordinate. Martin is
      trying to find a way to clarify these concepts, since you seem to
      find them unclear.</p>
    <p>What would make it clearer to you that CF declares that the
      height scalar variable mentioned in this discussion qualifies as a
      true or full or complete (or whatever word you prefer) coordinate
      and is not relegated to auxiliary coordinate status?<br>

    Grace and peace,<br>

              Hi Martin,<br>
              <br>
              The terminology entry has also been updated:<br>
              <br>
              auxiliary coordinate variable<br>
              <br>
              Any netCDF variable that contains coordinate data, but is
              not a coordinate variable (in the sense of that term
              defined by the NUG and used by this standard - see below).
              Unlike coordinate variables, there is no relationship
              between the name of an auxiliary coordinate variable and
              the name(s) of its dimension(s).<br>
              <br>
              scalar coordinate variable<br>
              <br>
              A scalar variable (i.e. one with no dimensions) that
              contains coordinate data. Depending on context, it may be
              functionally equivalent either to a size-one coordinate
              variable (Section 5.7, "Scalar Coordinate Variables"<<a
href="http://cfconventions.org/cf-conventions/cf-conventions.html#scalar-coordinate-variables"
                target="_blank" moz-do-not-send="true">http://cfconventions.org/cf-conventions/cf-conventions.html#scalar-coordinate-variables</a>>)
              or to a size-one auxiliary coordinate variable (Section
              6.1, "Labels"<<a
href="http://cfconventions.org/cf-conventions/cf-conventions.html#labels"
                target="_blank" moz-do-not-send="true">http://cfconventions.org/cf-conventions/cf-conventions.html#labels</a>>

                target="_blank" moz-do-not-send="true">http://cfconventions.org/cf-conventions/cf-conventions.html#collections-instances-elements</a>>).<br>
              <br>
              <br>
              ​The phrase ​"and used by this standard" allows, I think,
              the scalar coordinate variable to not be an auxiliary
              coordinate in the right context (i.e. when it's numeric).<br>
              <br>
              Does that make sense?<br>

              <br>
              I'm afraid I'm not undrestanding how you are
              distinguishing between "auxillary" and other coordinates.
              The terminology section of the CF Convention says that a
              variable is an auxillary coordinate if it contains
              coordinate data and is not an NUG coordinate. The
              definition of a scalar coordinate states that a scalar
              coordinate can be either an auxillary coordinate or a
              coordinate variable .. so the "height" variable here is
              both a scalar coordinate and an auxillary coordinate. It
              is clearly not a NUG coordinate variable.<br>

              I'm still not convinced of the utility of axis for
              coordinate variables<br>
              that aren't true coordinate variables, but this case

              one, does it? In this case isn't height a true (scalar)

              >><br>
              >>     I'd just like to check one aspect of the
              conformanc document, which came to our attention when
              somebody ran the CF checker on some CMIP5. If you check
              using the convention version declared in the file, 1.4, it
              will raise an error if there is a scalar coordinate
              variable with the axis attribute set, e.g.<br>
              >><br>
              >>     float tas(time,lat,lon);<br>
              >>          ......<br>
              >>          tas:coordinates = "height" ;<br>
              >>     float height ;<br>
              >>          ....<br>
              >>          height: axis = "Z";<br>
              >><br>
              >>     In this case "height" variable is, following
              the logic of section 1.2 of the convention, classed as an
              auxillary coordinate because it is not of the form "height
              (height) ; ".<br>
              >><br>
              >>     The error message appears to relate to a line
              in the conformance document saying that "The axis
              attribute is not allowed for auxiliary coordinate
              variables." If the checker is asked to use a later version
              of the convention, the error message goes away, but the
              requirement is still there in the conformance document.<br>
              >><br>
              >>     It looks to me as though it should be removed
              from the conformance document. The convention document
              says, in section 4. that "The methods of identifying
              coordinate types described in this section apply both to
              coordinate variables", referring to the use of the axis
              attribute, which appears to directly contradict the line
              of the conformance document cited above. But is there
              another part of the convention that requires some
              restriction on the use of the axis attribute?<br>
              >><br>
              >>     This construction is widely used in CMIP
              data, so we should get this point cleared up.<br>
