[ncl-talk] Question on regridding PATMOS-x data

[Mary Haley]

Xinyue,

Thanks for including the output. Something doesn't make sense here, because
the "which" command found the ESMF_RegridWeightGen executable, but the the
"ls -l" command did not.

What kind of system is this and how did you install NCL? I do see this is a
Mac system, but what version of MacOS are you running?

Also, what does the following echo:

ls -l $NCARG_ROOT
ls -l $NCARG_ROOT/bin

I'm trying to see if there's something wrong with the file permissions that
would cause this inconsistent information.

Thanks,

--Mary
