Hello! I have tried to run the example climate_network.py, I have also downloaded the air.mon.mean.nc from the link you suggested, but I get this error.. Do you know how could I solve it?

Thank you very much

Hi @sofiafarina ,

sorry for the late response. The NETCFD File you are using doesn't seem to be a NETCFD File. Please check on that. Here are the problem codes from the official website: http://cucis.ece.northwestern.edu/projects/PnetCDF/doc/pnetcdf-c/Error-Codes.html

Bests, Lena
