[ncl-talk] Problem with ESMF_RegridWeightGen

Thu Apr 5 11:01:15 MDT 2018

Hi Felix,

If it can't find the ESMF_RegridWeightGen executable, then this would
usually mean that $NCARG_ROOT/bin is not on your search path.  However, as
you pointed out, the NCL binary that you downloaded has this executable
included with it, so something else is going on with your environment.

My guess is that you may be using a different version of NCL than what you
think, or else $NCARG_ROOT/bin is NOT on your search path, and you are
executing NCL by explicitly giving it the full path to the NCL executable,
i.e.:

/xxxx/yyyy/bin/ncl my_script.ncl

I need to know how your environment is set up and how you are executing
NCL. On the UNIX command, before you run your script, can you type the
following four commands and send the output to ncl-talk:

which ncl
ncl -V
env | grep NCARG
which ESMF_RegridWeightGen

Then, also tell
us
 how you are running "ncl". That is, are you typing:

ncl my_script.ncl

or

/xxxxx/yyyy/bin/my_script.ncl

where /xxxx/yyyy is the path that NCARG_ROOT is set to?
