Re: Plot precipitation with multiple WRF files

Hi Ioannis,

I couldn't get your attachment unfortunately, but I can take a guess. The error is telling you that the first argument of "wrf_user_getvar" is not the expected type.

The first argument to wrf_user_getvar must be a variable that was returned from either "addfile" or "addfiles".

If you have an older version of NCL (5.2.1 or older), then you can only use a variable returned from "addfile" and not "addfiles".
