Re: [ferret_users] netcdf longitude module problem

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.

Hi all;
       I want to pass some ferret generated netcdf files to
a colleague who uses ARCgis, and the non-global grid range
brackets 0 longitude so that the netcdf grid ends up having
..359, 360, 361, 362... longitudes, which ARCgis can't handle.
Is there any easy way to make the longitude grid go ..359, 360, 1, 2..?

ie enforce longitude >=0 and <=360

my longitude axis is:
DEFINE AXIS/modulo/X=12.75W:119.25E:0.5/UNIT=DEGREE xlone5f
