I'll second the call that you should upgrade to the newest version of ncl (v6.3.0). I think your current error is occurring due to you loading shea_util before contributed. Try loading the files in this order:<br>
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"<br>
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"<br>
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"<br>
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/shea_util.ncl"<br>
<br>
<br>
<br>
If that doesn't work let ncl-talk know..<br>

it says that such function is in the “contributed” file.<br>

you need to add statements such as:<br>

ok, wow. Don’t send the same message 3 times, if the first answers weren’t complete at least expand and attempt something not just copy paste the same lines again.<br>
<br>
as said before .Z means it’s compressed. gunzip merg_<a href="tel:2016020123" value="+12016020123">2016020123</a>_4km-pixel.Z will uncompress it. Then you have a binary file as a small amount of googling would have told you.<br>
The same search would have linked you to various messages on here and various scripts where other people have included simple examples of this file type (myself included). Here is an example of reading and making a simple plot. There are plenty of examples on how to write netcdf on the NCL website so you should develop code from there. Most simple example at bottom of script below.<br>
