Hello Linda and Mr. Chiswell,

I am back from my leave and happy to work once again on the CMC Unidata
project.

I understand that there was a temporary interruption of the GEM data feed
to the IDD system in July. We believe that the LDM server was shut down
accidentally, and this still being an experimental set-up, we didn't have
a mechanism in place to ring the bell in case of problems.

I say "temporary interruption" because, after the server was re-installed
in August 2000, it seems to have worked normally ever since at our end.
The logs show that the GEM products are successfully inserted in the LDM
queue on a daily basis. Could you please (check and) confirm that you are
not getting any GEM products from dns2.cmc.ec.gc.ca . The permissions in
the ldmd.conf file are set as follow:

allow   ANY
^((localhost|loopback)|(127\.0\.0\.1\.?$)|([a-z].*\.unidata\.ucar\.edu\.?$))
allow ANY shemp.unidata.ucar.edu

Once the feed is re-established, I should inform Christian Page of the
Universite du Quebec a Montreal of the availability of GEM data via the
IDD system.

With best regards,
Ekaterina

Hi Richard,

We received a question today about the GEM data.  I've appended it below.
Can you provide an update?  The last info I received from you was Aug 24,
2000.  I've attached it after the most recent inquiry.

Thanks,
Linda

Christian,

GEM data from CMC is not available on the IDD yet. The person that was
leading the effort for installing the LDM and sending the data to us went
on leave and I do not know of any progress after that. I'll CC Linda
Miller in case she knows any more information and so we know users are
interested in the data.

On the IDD, the ETA is available on the 207 (alaska) grid in addition to
the
20, 40 and 80km conus grids you list below.
