I have a 3d grid of data where the x dimension is longitude, y is latitude, and z is elevation. The longitude range goes from 0.0 to 357.5. When I map this data to spherical coordinates, there is a longitudinal slice missing since the data range only goes to 357.5, not 360.0. So, my question is, how can I add another slice of data to my data field? That is, I want to add an x position of 360.0 whose data values are the same as when x equals 0.0. I don't know what to do to change the dimensions of a field.
Thanks for any help. Betsy
