 Dear Mark,

 > Does such a Field instance conform to your view of the CF data model
 specification?

 I'm afraid not! I think the field you describe has:

    5 '''un'''ordered domain axes ({size}): h{1}, t{1}, x{96}, e{1}, y{73}

    a 2D array of data(y, x)

    4 dimension coordinates:

      time(t), height_level(h), latitude(y), longitude(x)

    5 auxiliary coordinates:

      forecast_reference_time(t), forecast_period(t),
      ensemble_member(e), source(e), institute(e)

 In my field, domain axis ''e'' has no dimension coordinate and
 ''ensemble_member'' is an  auxiliary coordinate. This is because I am
 presuming that, even though it's numeric, the coordinate's value seems
 arbitrary to me. However, I could just as easily have made
 ''ensemble_member'' one of 5 dimension coordinates and had only 4
 auxiliary coordinates.

 All the best,

 David
