Hi Mary,

Sorry for the delay. Please find attached a sample script.  The data
used in this script is from the "Example data sets available at the
NCL home page"

The WRF library loaded after the standard NCL libraries are from

In fact the Bus Error appears only when using this version of the
WRFUserARW_add.ncl The WRF website says that this is an experimental
version of the said library script. On the other hand, when I use
5.1.1 with this library, there is no Bus Error

The version available at
"$NCARG_ROOT/lib/ncarg/nclscripts/wrf/WRFUserARW.ncl" thankfully does
not give the Bus Error with both versions.
