Thank you for the information. Yes, it does work perfectly.

Thanks

I have replaced the "relative humidity" variable by "specific humidity" variable but having problem to replace the "long name" of the variable. Although I have declared the variable_at_long name = "Specific Humidity" it is showing "unknown" at 500 hPa. I am attaching the plot for your
