<p>After upgrading to NCL 6.5, all is well with ncl_filedump. It's
possible that under 6.3 some of the environment variables were not
set correctly.</p>

<p>Thank you Dennis. Unfortunately, I still just get the
error message, so apparently it's something peculiar to my
machine. I wonder if there could possibly be something
wrong in the way I've configured NCL? <br>
</p>
<p>I could update to the latest version of NCL.</p>

<div>NCL uses look-up tables to match-up parameter id

</div>
<div>Unfortunately, GRIB is a moving target and NCL
developers are not privy to information or it is just
not publicly available.<br>
<br>

<div>So, for example:<br>

<div>NCL unpacks the variables and creates the appropriate
dimension names. It just does not have the needed lookup
info.<br>

<p>I am trying to find out what's inside a grib2
