[Gaurav Tiwari]

Hi, I have tried whatever you have suggested but still facing problem as
mentioned below. Kindly run my script by using any wrfoutput.nc file so
that my script will be cross checked also and it will be easy for you to
solve my problem.

Script is attached below.

Thanks and regards,
