Hi Russ, re: > Finally got service back. turned to be a problem with the SSEC > firewall. MANY people lost data this weekend . Was it some sort of Friday afternoon tweak that went bad? re: > I don't remember if I aked you this Question.... > Is the Unidata national composite contained in the LDM feed? Yes, it is available in the FNEXRAD feed. The easiest way to find out what is in a particular IDD datastream is through the LDM 'notifyme' utility. Here is an example: <as 'ldm'> notifyme -vl- -f ANY -h your_upstream_feed_host This invocation of 'notifyme' asks 'your_upstream_feed_host' what data it is receiving from all datastreams. If you want to check what it is receiving in the FNEXRAD feed, the invocation would be: notifyme -vl- -f FNEXRAD -h your_upstream_feed_host Similarly, you can use 'notifyme' to ask your local machine what it is receiving in any/all datastreams. Here is an example invocation asking your local LDM to list what it has received in the FNEXRAD feed in the past 3600 seconds: notifyme -vl- -f FNEXRAD -o 3600 The following is some example output from 'notifyme' for FNEXRAD products received on the local host in the past 3600 seconds: <as 'ldm'> notifyme -vl- -f FNEXRAD -o 3600 Jun 15 14:40:59 notifyme[26562] NOTE: Starting Up: localhost: 20090615134059.332 TS_ENDT {{FNEXRAD, ".*"}} Jun 15 14:40:59 notifyme[26562] NOTE: LDM-5 desired product-class: 20090615134059.332 TS_ENDT {{FNEXRAD, ".*"}} Jun 15 14:40:59 notifyme[26562] INFO: Resolving localhost to 127.0.0.1 took 0.000462 seconds Jun 15 14:40:59 notifyme[26562] NOTE: NOTIFYME(localhost): OK Jun 15 14:41:00 notifyme[26562] INFO: 1198469 20090615142800.444 FNEXRAD 000 rad/NEXRCOMP/1km/n0r_20090615_1425 Jun 15 14:41:00 notifyme[26562] INFO: 2778541 20090615142808.578 FNEXRAD 000 radar_mosaic_nathr !grib2/unidata/UPC_255/#000/200906151425F000/N0R/0 - NONE! 000000 Jun 15 14:41:00 notifyme[26562] INFO: 92584 20090615143000.795 FNEXRAD 000 rad/NEXRCOMP/4km/ntp_20090615_1428 Jun 15 14:41:00 notifyme[26562] INFO: 1191027 20090615143100.961 FNEXRAD 000 rad/NEXRCOMP/1km/n0r_20090615_1429 Jun 15 14:41:00 notifyme[26562] INFO: 89630 20090615143106.983 FNEXRAD 000 rad/NEXRCOMP/2km/n1p_20090615_1429 Jun 15 14:41:00 notifyme[26562] INFO: 2777099 20090615143207.644 FNEXRAD 000 radar_mosaic_nathr !grib2/unidata/UPC_255/#000/200906151431F000/N0R/0 - NONE! 000000 Jun 15 14:41:00 notifyme[26562] INFO: 1175073 20090615143400.504 FNEXRAD 000 rad/NEXRCOMP/1km/n0r_20090615_1432 Jun 15 14:41:00 notifyme[26562] INFO: 92440 20090615143500.694 FNEXRAD 000 rad/NEXRCOMP/4km/ntp_20090615_1433 ...

You can use 'notifyme' to list out products whose product IDs match a specific pattern.

GEMPAK can do the same. Cheers, Tom -- **************************************************************************** Unidata User Support UCAR Unidata Program (303) 497-8642 P.O.
