how to handle the array in netCDF4 file without a maps array.

[XiaoLinhong]

Sometimes, the array in a netCDF4 file is used a Lambert projection, like the out files of WRF model， which means its dimensions don't match its coordinates. in this case, the corresponding maps are not existence.

How can I handle this?

self.dataset[grid][dim] = BaseType(dim, vars[dim][:],
KeyError: 'south_north'
