Re: How to put user specified variable name in "wrf_PressureLevel3.ncl" example plot

Kamal,

The WRF functions use "description" instead of "long_name", so try:

> variable@description = "Specific Humidity"

--Mary

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 convenience.
