Hi Scott, I apologize for taking so long to get back to you... re: > I am working as part of the ARM climate research facility. We are > installing a series of new radars at our fixed and mobile sites. While > these are being installed I am experimenting and learning some of the > software involved, and to do this I would like to be ingesting a LDM > feed of the NEXRAD data. I am located at Argonne National Lab in Chicago. OK. This should be doable. re: > I have installed LDM on my machine anl-titan.mcs.anl.gov which is > at 140.221.11.74. Could I get access to an official feed source for > IDS|DDPLUS|NEXRAD2? For now, please setup your LDM feed REQUESTs to use idd.cise-nsf.gov. It would be best if your IDS|DDPLUS REQUEST is kept separate from your NEXRAD2 request. For instance: request IDS|DDPLUS .* idd.cise-nsf.gov request NEXRAD2 .* idd.cise-nsf.gov Comments: - It is possible that you only need/want to ingest a portion of the NEXRAD2 datastream. If this is the case, you should adjust your REQUEST regular expression to request only those stations of interest. If you are not already familiar with the LDM 'notifyme' utility, you should consider investing a small bit of time to learn how to use it. For instance, 'notifyme' can be used to inform you of what an upstream feed host is getting and if it has ALLOWed you to request those data: <as 'ldm'> notifyme -vl- -f NEXRAD2 -h idd.cise-nsf.gov The output from 'notifyme' will show you the Product IDs of the products in the feed(s) you specify.
