Howdy Gilbert, I noticed this entry in the NCO RFC Memo last week RFC 13491 - Modify the NWSTG LDM Proc feed of Canadian radar data to only write a selected group of sites to disk for TG (Telecommunications Gateway) ingest (line 216) and headed dissemination of SDCN01 CWAO. This change will not impact the incoming LDM data that is already being distributed internally. SBNRC (Satellite Broadcast Network Review Committee) requested fewer sites be sent on to TG/SBN due to high data volume. AWIPS is already able to handle this data. This data was turned off early in the year due to saturation on the SBN. Phase 1 of the realignment was completed on September 17 to make room for this data. NCO will only be turning on sites that are nearest the US border with Canada initially. To be implemented in College Park and Boulder on December 9 and 10 from 1500Z to 1600Z each day. The active TG ingest site will be done on day 1 and inactive site on day 2. daryl ________________________________________ From: ldm-users <ldm-users-bounces@xxxxxxxxxxxxxxxx> on behalf of Sebenste, Gilbert <sebensteg@xxxxxxx> Sent: Monday, December 9, 2024 3:44 PM To: Ryan Hickman; LDM Users; NOAAPORT Subject: Re: [ldm-users] [External] [noaaport] Fwd: ADMIN NOTICE NOUS41 KWBC There was a 5 minute outage this morning of NOAAport shortly after 14Z. Since then, however, I have not seen any Canadian radar data on the SBN under the header of “SDCN01 CWAO”. I am wondering if they had an issue.

This study identified that reorganizing the data on the various channels will improve the timeliness of distributed products. The first change recently implemented was to move gridded binary (GRIB), GRIB two (GRIB2), and Binary Universal Form for the Representation (BUFR) formatted data from the NMC channel to the NMC2 channel. Refer to Service Change Notice (SCN) 24-54: https://www.weather.gov/media/notification/pdf_2023_24/scn24- 54_channel_realignment_to_SBN_aaf.pdf for more details about this change. The space freed on the NMC channel provided by the first change allows the next change to occur, adding Canadian Radar data to the SBN. (Channel: NMC | Priority: 0 | Bandwidth: 20 | Port: 1201 | PID: 101). However, only the following 23 of 31 available radars will be added to minimize SBN impact, and reflect those adjacent to the United States: World Meteorological Organization (WMO) header: SDCN01 CWAO CASSS - Silver Star Mountain, British Columbia (BC) CASAG - Aldergrove, BC CASSM - Strathmore, Alberta (AB) CASSU - Schuler, AB CASBE - Bethune, Saskatchewan (SK) CASFW - Foxwarren, Manitoba (MB) CASWL - Woodlands, MB CASDR - Dryden, Ontario (ON) CASMR - Montreal River Harbour, ON CASET - Exeter, ON CASBI - Britt, ON CASKR - King City, ON CASFT - Franktown, ON CASNE - Thunder Bay ON CASBV - Blainville, Quebec (QC) CASSF - Ste-Francoise, QC CASMA - Mt Apica, QC CASVD - Val d'lrene, QC CASCM - Chipman, New Brunswick (NB) CASGO - Gore, Nova Scotia (NS) Additionally, more WMO Headers containing model data, related to phase 1, were discovered and need to move. (Channel: NMC | Priority: 0 | Bandwidth: 20 | Port: 1201 | PID: 101) to (Channel: NMC2 | Priority: 5 | Bandwidth: 30 | Port: 1203 | PID: 103): ^(MZ....) ^(LZ....): NAM Nested Model data ^(HC....) ^(HO....) ^(HP....) ^(HU....) ^(HV....): SSI GFS model This data is expected to move on or about 1200 Coordinated Universal Time (UTC) December 9, 2024.If a Critical Weather Day has been issued, this change will be postponed to 1200 UTC on the next non-Critical Weather Day for the following dates: December 10, 16 and 17, 2024. No change is expected to the data feed at the receiver. If no issues are experienced, the configuration will remain in place. If any issues are identified, the changes will be evaluated, and a new implementation date will be determined. We encourage all NOAAPort/SBN/NWWS users to closely monitor this SCN during the transition period for updated information.
