Re: [ferret_users] netcdf longitude module problem

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

Hi Lev,
Ferret won't write a dataset with a non-monotonic axis, which would 
violate the CF standard for netCDF files.  Would it make sense for 
ARCgis to have two datasets, one for longitudes = ...359, 360, and a 
second for 1, 2, ... ?

Does anyone know whether there a standard for NetCDF and ARCgis?  If so 
maybe one could write an function that would create that style of file. 
Beyond that I imagine that there might be things in NCO which could 
change the coordinates in a Ferret file.
