When you refer to a "correct" aspect ratio aren't you talking about an interpretation issue? You only know that a one degree lon spacing corresponds to a smaller great circle distance the closer you get to the pole because you are interpreting the coordinate as a longitude coordinate. If you're not interested in that interpretation of the coordinate variable then it seems to me that it doesn't matter which one you assign to the y-axis. Brian eaton@ncar.ucar.edu
