[Ncep.list.idp.mrms.users] [Ncep.list.idp_support] OPEN - TID: 809080283 - IDP - URGENT: Paducah radar data not being used in MRMS (since at least12z)?

The config file edit we proposed would remove all inputs to MRMS from KPAH.
MRMS would produce products with input from adjacent radar sites. We are
not certain of the quality of products that are produced with inputs from
nearby stations.

Hope this helps,
