Re: dim_avg_n_Wrap and dim_avg_Wrap do not transfer all meta data

Hi Rich,

Dennis and I discussed this offline, and I think you have found a
bug. It will be fixed immediately if so.

Meanwhile, I believe you can fix this yourself by editing (or making
a copy of) $NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl,
searching for "function dim_avg_Wrap" and adding the line:

  copy_VarAtts (x, xave) ; copy attributes

right after:

  xave = dim_avg(x) ; arithmetic ave [no meta data]
