Re: GRIB2

Hi Mary,

I'm running the version 1.2.0. I could find the grib2_codetables directory
doing as you said:

>>> import Ngl
>>> print Ngl.pynglpath("ncarg")
/usr/lib/python2.4/site-packages/PyNGL/ncarg

wrf_at_operacao0:/discolocal/wrf/tmp$ ls
/usr/lib/python2.4/site-packages/PyNGL/ncarg
colormaps data database fontcaps graphcaps grib2_codetables pynglex
sysresfile

Have some environment variable that I could try to set?
