Re: [ferret_users] Error creating coord. vars: WRF output in Ferret 6.2

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi all -
Hein and I exchanged some more details, and I have found that this is a 
bug, and we have a fix for it.

When the file doesn't include the coordinate variables (that is, Time, 
south_north, west_east are not listed as variables in the file, or are 
not returned from the netCDF/OPeNDAP library as variables), then Ferret 
v6.2 was not getting the axis name when it goes to write the coordinates 
when it does the SAVE.  This is an easy fix, and it'll be in the 
upcoming Ferret release.
