Subject: Change to TDWR SPG Product Dissemination on or
around November 19, 2019
On or around November 19, 2019, NWS will change the public
dissemination of Supplemental Product Generator (SPG) products,
which use Terminal Doppler Weather Radar (TDWR) data.
The SPG products to be terminated are:
1. Product 181 – Base Reflectivity: 16 data level
2. Product 32 – Digital Hybrid Scan Reflectivity
3. Product 78 – Surface Rainfall Accumulation One Hour Running
Total
4. Product 80 – Surface Rainfall Accumulation Storm Total
5. Product 81 – Digital Precipitation Array
6. Product 82 – Supplemental Precipitation Data
7. Product 138 – Digital Storm Total Precipitation
The following SPG product will be added:
8. Product 180 – Base Reflectivity: 256 data level
Alternate sources of data include precipitation products from
neighboring WSR-88Ds or the MRMS system.
The NWS will begin testing this change at Charlotte, NC - TCLT.
If NOAA's Level III product dissemination, ingest and archival
systems are shown to be properly functioning and configured as
expected, the change will be activated at the remaining 44 sites
on December 4, 2019.
Table 1 and 2 contain the WMO headings of the products 6to be
terminated and added.
