Hi Laura,

There is definitely an issue with the minus sign in the variable name.  If
you do something like this:

var = f->lwp37_mid-high_daynight_mon

then NCL thinks you are trying to read "lwp37_mid" off the file and
subtract the variable "high_daynight_mon" from it.

To work around this, enclose the variable name in $"..."$:

var = f->$"lwp37_mid-high_daynight_mon"$

You can also do this:

varname = "lwp37_mid-high_daynight_mon"
var = f->$varname$
