First, please be aware that the NGRID and CONDUIT (aka NMC2) feeds contain the majority of the data flowing in the IDD. Given the volume of the data, you may need to split your data request into several requests. Until we determine how good/fast your Internet connection is, let's start by requesting all of the data in each feed. To do this, add the following two lines to your ~ldm/etc/ldmd.conf file: request NGRID ".*" idd.cise-nsf.gov request CONDUIT ".*" idd.cise-nsf.gov I fully expect that your Internet connection is not fast enough to get all of the CONDUIT data on a single request. I also expect that you are mainly interested in the global model data available in CONDUIT, not the data that is focused over the US. Because of these two assumptions on my part, you might want to try requesting just the global model output from CONDUIT and splitting the request 5 ways: request NGRID ".*" idd.cise-nsf.gov request CONDUIT "MT.gfs_CY.*[05]$" idd.cise-nsf.gov PRIMARY request CONDUIT "MT.gfs_CY.*[16]$" idd.cise-nsf.gov PRIMARY request CONDUIT "MT.gfs_CY.*[27]$" idd.cise-nsf.gov PRIMARY request CONDUIT "MT.gfs_CY.*[38]$" idd.cise-nsf.gov PRIMARY request CONDUIT "MT.gfs_CY.*[49]$" idd.cise-nsf.gov PRIMARY After we get an idea of how good (or bad) your Internet connection is, we may want to adjust your request lines. Second item: since you will be requesting a lot of data, I want to make sure that your LDM queue is large enough. I recommend that you set your LDM queue size to at least 2 GB. This is done by modifying the $pq_size variable in ~ldm/etc/ldmadmin-pl.conf: $pq_size = "2G"; After making a change in ~ldm/etc/ldmadmin-pl.conf, you will need to delete and remake your LDM queue: <as 'ldm'> cd ~ldm ldmadmin stop <- just in case your LDM is running ldmadmin delqueue ldmadmin mkqueue -f <- the '-f' (for 'fast') assumes you have enough disk for the queue ldmadmin start <- to start the LDM Now, assuming that you have correctly setup /etc/syslog.conf for LDM logging, you should see a 'Starting up' message in ~ldm/logs/ldmd.log. If your LDM does not start, you should see an error message in ~ldm/logs/ldmd.log that tells you where in ~ldm/etc/ldmd.conf there is an error (and errors are typically typos). > the two upstream sites that were given to us are follows: > > idd.cise-nsf.gov > idd.unidata.ucar.edu (backup) > > If something else is needed, i will send you in another email. OK. > I would appreciate much your help. Thanks for your help > (Sorry my english) No worries. Please let us know if the above helped. > Andr�s Vidal Cheers, Tom **************************************************************************** Unidata User Support UCAR Unidata Program (303) 497-8642 P.O.
