There is no way to set the scale on the vertical axis at this time. I'll add that to the list of things to do. The basic problem is that the units indicate meters when in fact they are -meters. The netCDF CF convention includes an attribute that specifies whether positive values are up or down. The netCDF-Java CDM uses this attribute if present even for non-CF convention files. If you open the attached NcML file, it will add that attribute to the data and then your profiles will show with 0 at the top and negative values for the vertical. You can use this with other files if you just change the name in the XML. Or, if you want to make this a Data Source Type, let me know and I can let you know how to do that.
