Re: [ncl-install] help installing ncl_ncarg-6.0.0

Chandra,

I don't know how OLR is being calculated, because we don't have that quantity in our version of WRFUserARW.ncl.

Are you perhaps using a modified version of WRFUserARW.ncl that somebody modified to add this quantity at your site?

Or maybe you are loading another script entirely that has its own defined version of wrf_user_getvar?

Are there any "load" commands at the top of your NCL script?
