[ferret_users] inconsistent data grids: File needs axis attributes on coordinate variables indicating correct direction

[Patrick Brockmann <patrick.brockmann@xxxxxxxxxxxx>]

Hi ferreters,

A colleague has encountered a strange problem as he was trying to

nicely respect the netCDF CF conventions to describe a curvilinear grid (NEMO configuration).

ferret complains about some inconsistent data grid and missing axis attributes.

use notok.nc 
          *** NOTE: 
          *** NOTE: Could not adjust grid for variable mask_T 
**ERROR: inconsistent data grids: File needs axis attributes on coordinate variables indicating correct directions

Stranger, if I change the name of the dimension, then the file

is read. I have not been able to fix this by adding a direction attribute as requested.

The file is simple as:

notok.nc

Description: Cdf file
