[IDD #GSD-112338]: New LDM installation for UNC-Charlotte

> Hello,

Hello Elie, 

[comments in text]

Sounds good.

Yes, meteo.uncc.edu has both forward and reverse DNS and we (Unidata) can feed 
the machine, but there may be 
machines electronically closer. Please use our node: idd.unidata.ucar.edu while 
setting up, there is a possibility we may ask you to feed from another machine 
in the future (this would simply require an edit in your ldmd.conf). 

You can check connectivity using the LDM 'notifyme' command:


notifyme -vl - -h idd.unidata.ucar.edu -f [FEEDTYPE}

or leave of the -f and it defaults to "ANY"..this will return product headers 
if you are allowed to feed.

Unidata's LDM/IDD currently delivers real time data, Unidata does provide 
"pull" access
to short term (1-3 months) from our server:


THREDDS and RAMADDA access to short term data as well as case studies on 
RAMADDA are available from the
above URL.

You're at the right place :)

Yes, do you plan on running McIDAS?

GEMPAK builds come with the needed decoders for data from the LDM/IDD, so if 
you are planning on solely using GEMPAK for viz you will be complete with a 
GEMPAK and LDM install.

ldmd.conf examples can be found at the LDM page:


or directly:


and the pqact entries --for GEMPAK--are provided in the GEMPAK distribution.

..and a request, if possible, please direct support questions to their specific
