SUBJECT: ADDITION OF DUAL POLARIZATION WSR-88D PRODUCTS TO SBN
/NOAAPORT AND RPCCDS: EFFECTIVE WITH WSR-88D DUAL
POLARIZATION /NOVEMBER 2010 BETA TEST/
EFFECTIVE WEDNESDAY NOVEMBER 17 2010...AT APPROXIMATELY 1500 COORDINATED UNIVERSAL TIME /UTC/...THE NWS WILL BEGIN DISSEMINATING RADAR PRODUCTS LISTED IN TABLE 1 VIA THE RADAR PRODUCT CENTRAL COLLECTION DISSEMINATION SERVICE /RPCCDS/ AND SBN/NOAAPORT. OTHER BETA TEST SITES WILL BE ADDED AS THEY ARE MODIFIED. DURING THIS TEST PERIOD... NWS WILL EVALUATE COMMUNICATIONS LOADING FOR IMPACTS AND DECIDE WHETHER TO DISSEMINATE DUAL POLARIZATION PRODUCTS FROM ADDITIONAL SITES MODIFIED DURING FULL SCALE DEPLOYMENT.

THE FALLBACK PLAN IS TO DISTRIBUTE DUAL POLARIZATION PRODUCTS ONLY VIA NOAAPORT OR RPCCDS... WHICH WOULD BE DONE BY FILTERING SDUS8I PRODUCTS FROM DISSEMINATION. THIS PLAN REQUIRES EXCLUSIVE USE OF SDUS8I FOR DUAL POLARIZATION. CURRENTLY THE DIGITAL PRECIPITATION ARRAY PRODUCT /DPA/ HAS THE FOLLOWING HEADING: SDUS8I. CONSEQUENTLY THE PRODUCT IN TABLE 2 WILL BE CHANGED NATIONALLY TO SDUS5I BEFORE BEGINNING DISSEMINATION OF DUAL POLARIZATION PRODUCTS.
TABLE 2: REASSIGNED WMO HEADINGS FOR WSR-88D AND TDWR SPG PRODUCT TTUSII NNN PRODUCT DESCRIPTION DIRECTORY SDUS5I DPA HOURLY DIGITAL PRECIPITATION ARRAY 81/DPA DS.81DPR WHEN FULLY IMPLEMENTED THE NOAAPORT AND RPCCDS COMMUNICATIONSTHROUGHPUT OF WSR-88D PRODUCTS WILL INCREASE BY A FACTOR OF 2.8 ABOVE LEVELS REACHED WHEN HIGHER RESOLUTION BASE PRODUCTS WERE ADDED IN EARLY 2010 VIA TECHNICAL IMPLEMENATION NOTICE 09-41. FOR EACH WSR-88D... THE AVERAGE HOURLY PRODUCT VOLUME VIA RPCCDS WILL BE APPROXIMATELY 14.5 MEGABYTES /MB/ AND THE AVERAGE DAILY VOLUME WILL BE 345.8 MB. WHEN FULLY IMPLEMENTED THE AVERAGE DAILY VOLUME FOR ALL WSR-88D RADARS WILL BE 53.9 GIGABYTES /GB/. WORSTCASE HOURLY THROUGHPUT IS ESTIMATED TO REACH 48 MB FOR A SINGLE RADAR AND 4.2 GB FOR ALL 200 RADARS /155 WSR-88D AND 45 TDWR/. ON NOAAPORT PRODUCTS ARE FURTHER COMPRESSED AND THEREFORE THROUGHPUT WILL BE REDUCED SOMEWHAT.
