 ==== Orthogonal multidimensional array representation of profiles
 
 If the profile instances have the same number of elements and the vertical coordinate values are identical for all instances, you may use the orthogonal multidimensional array representation.
-This has either a one-dimensional coordinate variable, `z(z)`, provided the vertical coordinate values are ordered monotonically, or a one-dimensional auxiliary coordinate variable, `alt(o)`, where `o` is the element dimension.
+This has either a one-dimensional coordinate variable, `z(z)`, provided the vertical coordinate values are in strict monotonic order, or a one-dimensional auxiliary coordinate variable, `alt(o)`, where `o` is the element dimension.
 In the former case, listing the vertical coordinate variable in the **coordinates** attributes of the data variables is optional.
