NCL plotgrids Fatal Error

Postby uwbeobachtung » Tue Dec 26, 2017 9:37 am

Hello Folks

I have installed WPS and WRF, no i am trying to run the command ncl util/plotgrids.ncl.
The following run is failed:

Code: Select all

fatal:Could not open ($NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl)
fatal:error at line 7 in file util/plotgrids.ncl

Now, i try to get the env (bashrc) from $NCARG_ROOT, and it is /usr:
Code: Select all

Then i will check if the Path /usr/lib/ncarg/nclscripts/csm/ exist and '($NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl)' is correct, and yes, it is:

Code: Select all
:/WRF/WPS# cd /usr/lib/ncarg/nclscripts/csm/
:/usr/lib/ncarg/nclscripts/csm# ls -la

I don't know why i received an fatal error of NCARG_ROOT in the plotgrids.ncl Script?
What should i do?

This problem seems to be with an incorrect installation of ncl using the 'sudo apt install ncl-ncarg' or 'apt-get' method. (Seems to happen on ubuntu and debian). NCAR doesn't support the apt-get version of NCL. You should uninstall ncl-ncarg and install NCL from the NCL website.

Typically, NCL would be placed in /usr/local/ncarg (or some directory like that). It seems a red-flag for this problem is having NCARG_ROOT set to /usr.
