Issues with netCDF and opengrads-2.0

Mon May 11 19:49:30 EDT 2009

Hi Arlindo:

I emailed last week about having a problem reading in a netCDF file with
grads-2.0.a5.oga.4, specifically the netCDF :title was too long (more than
256 characters).  The files are now within this limit, and grads-2.0.a5.oga
reads them okay.  However, the same data set is served via OPeNDAP and
the same grads binary does not work.  I'm not sure I understand the error
list (see below) but I suspect a similar issue.  I've tried
grads-1.9.0-rc1 and
it works fine.  I've attached the netCDF file as an example
(ns01_2009_04_21.nc).
Again, grads-1.9.0-rc1 can read both the local and OPeNDAP data set;
grads-2.0.a5.oga.5 can now read the local one but not the OPeNDAP one.

Below is the result when reading this via OPeNDAP as follows:
