Hi Milika,The file uses the "string" type for attributes, and Ferret/PyFerret currently only implements reading of character-type strings. The NetCDF API has recently been adding functionality for this, but we have not yet worked through implementing this.
Here is a previous thread on this. The user was able to handle this by changing the file using NCO operators to change string-typed attributes to character type.
