Hi Bob, re: > The National Mosaic base-reflectivity data appears to not contain any > data in the past 2 days. Files are there, but they do not display any data: > > NEXRCOMP/1KN0R-NAT > > The Hydrid reflectivity appears OK: > > NEXRCOMP/1KDHR-NAT > > I'm receiving NEXRCOMP datasets from lead.unidata.ucar.edu I just finished answering another user's inquiry about missing N0R data. My investigations showed that we are getting N0R products, but they are only from the Pacific region and Puerto Rico. Since these products are not included in the NEXRCOMP 1KN0R-NAT composites, the products will have been empty or missing because of the lack of N0R data being sent by the NWS in NOAAPort. I did a search to see if there as an announcement about the availability of N0R products, but I didn't see anything relevant. It may be possible that the NWS is unaware of the CONUS N0R products being missing since the WFOs pretty much use the DHR products instead. The other thing that may or may not be relevant is this notice about software upgrades being done this morning and the affect on NEXRAD Level 2 data: Date: Thu, 06 May 2021 12:02:51 -0500 Maintenance activity is complete.
