Several NCL scripts are now preloaded, and you no longer need to
explicitly load them at the top of your own scripts. Here's a full
list of the preloaded scripts:
</p><p>
</p><pre> "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
"$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
"$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"
"$NCARG_ROOT/lib/ncarg/nclscripts/csm/shea_util.ncl"
"$NCARG_ROOT/lib/ncarg/nclscripts/csm/bootstrap.ncl"
"$NCARG_ROOT/lib/ncarg/nclscripts/csm/extval.ncl"
"$NCARG_ROOT/lib/ncarg/nclscripts/wrf/WRFUserARW.ncl"
</pre>
<p>
It's okay to still load these scripts even though it's no longer required. <br></p><p><br></p><p>----</p><p>Only, the ESMF_regridding.ncl need be loaded.<br></p><p><font color="#0000ff" face="微软雅黑, Tahoma"><i>load "$NCARG_ROOT/lib/ncarg/<wbr>nclscripts/esmf/ESMF_<wbr>regridding.ncl"</i></font></p></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Apr 4, 2017 at 10:47 PM, <a href="mailto:wangna@mail.iap.ac.cn">wangna@mail.iap.ac.cn</a> <span dir="ltr"><<a href="mailto:wangna@mail.iap.ac.cn" target="_blank">wangna@mail.iap.ac.cn</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div>
