[ncl-talk] Problem reading NETCDF-4 file created in v6.1.2

[Mary Haley]

Hi Dave,

It might be worth trying a new version of NCL on this script, since a
number of bugs have been fixed since then, pertaining to NetCDF files.

If you can't upgrade, then can you provide us with the NetCDF file and a
simple script that illustrates the cd_inv_calendar issue?

Thanks,

--Mary
