Hi Jim:  Following a chain of links from your URL eventually got me there,
but its not obvious.  Here is the direct link to CPAN:

http://www.cpan.org/modules/by-module/PDL/DHUNT/

The most recent version of 0.94--this will change when netCDF 4 is
supported (to something above 1, I think!)

Regards,

  Doug

By the way, the link to the PDL::NetCDF package on the Unidata webpage
(http://www.unidata.ucar.edu/software/netcdf/software.html#Perl) appears
to go to an inaccessible mail archive message.

Is there a URL we can go to to get information about PDL::NetCDF?

Thanks

Hi Cathy:  I maintain the PDL::NetCDF library, which interfaces with the
Perl Data Language extension for perl (see http://pdl.perl.org/).  This
gives much higher performance than the normal perl netcdf interface since
compact 'PDL' objects (n-dimensional matrices) are passed back instead of
perl arrays (stored internally as high-overhead linked lists).

I've just received a contribution from a user of a patch to
PDL::NetCDF to add netCDF-4 support.  I've yet to test it out, but this
will probably mean basic netCDF-4 support will be available in PDL::NetCDF
within a few weeks.

Hi:

We use the Perl netCDF module pretty extensively in our code. Will it be
able to support netCDF-4? I looked around and didn't see anything
specific. I believe the Perl module uses the much older version 2 API
and I'm not sure how supported it is.

Thanks,
Cathy Smith
