Hello, Thanks for contacting us. While we have products listed in our distributed ldmd.conf file, we don't always have data flowing/available. I'm not sure if we've ever had the HRRR sub-hourly - it's been more of a place holder in case we did get the data. We used to receive and re-distribute the CMC data, however we stopped receiving that data a while ago and haven't been able to reach a contact to get the data since. LIGHTNING is a restricted feed, so it's not something that is freely available. See below for information regarding the lightning data: "The REQUEST for the NLDN feed from UAlbany will only work after the user contacts the folks at UAlbany and satisfies them that the data will be used solely within the user's campus. The long standing restriction for LIGHTNING data to not be used outside of a site's campus applies to remote server access also - it is not allowed for a site to make NLDN or USPLN data available via a data server IF that server has access opened for outside of the site's campus." > Hello, > > I'm trying to add HRRRX sub-hourly data as well as data from the NLDN and > USPLN to my EDEX by uncommenting these feeds in the ldmd.conf file by > following the documentation in the EDEX user manual.
