Hi Kelly, Since your inquiry was not LDM-specific, I moved it into a different area of our inquiry tracking system (support-idd)... re: > we've come to an impasse in our web portal design that has caused us to > re-evaluate the policies for sharing our ldm feed. > > i wanted to be sure that the data that comes over the ldm is not > protected. we're in the throws of a nist-800-171 audit. its been quite > a ride. it would be good to know that the ldm feed is public. The _great_ majority of data being relayed by the LDM in the IDD have no restrictions on sharing. The current exceptions to this "rule" are: LIGHTNING - NLDN and USPLN lightning data WSI - this feed type was used by WSI to relay NEXRAD Level III products to paying customers quite some time ago. We think that it is no longer being used, so we are going to re-purpose the feed to relay new data PCWS - this feed was used to relay ACARS data re: > i also wanted to see what the policy conventions for sharing data with > other agencies. we've discovered municipal, educational and corporate > agencies fetching data from our feed. how are other ucar members setting > their policies for data sharing? The blanket ALLOWs that we are using on our top level IDD relay clusters basically look like: allow ANY-LIGHTNING-WSI-PCWS \.edu$ # All US .edus allow ANY-LIGHTNING-WSI-PCWS \.gov$ # All US .govs allow ANY-LIGHTNING-WSI-PCWS \.mil$ # for mil sites allow ANY-LIGHTNING-WSI-PCWS \.int$ # for ECMWF, EUMETSAT allow ANY-LIGHTNING-WSI-PCWS \.org$ # for Museum of Science, Renaissance Computing Institute (NC State), COLA, NMSU/CSBF, STAR Institute I hope that this helps!
