2. NOAA Weather Wire Service (NWWS) - legacy
Mission: Timely delivery of critical weather information Description: NWWS is a satellite data collection and redistribution system operated by the National Weather Service (NWS). NWWS singular purpose is to provide timely meteorological, hydrological, climatological, and geophysical information to state and federal governments, emergency managers, commercial users, media outlets (television, radio, social), and the general public.
Change is coming in
New things will appear 2014
SBN Channel 201 (NWWS only products) is operational for review this October 2014
Still in Development for 2015
Open Interface (OI) – still in development
Nlets Interface – currently under test

3. NOAA Weather Wire Service (NWWS) - 2
Mission: Timely delivery of critical weather information (No change) Description: NWWS is a satellite data collection and redistribution system operated by the National Weather Service (NWS). NWWS singular purpose is to provide timely meteorological, hydrological, climatological, and geophysical information to state and federal governments, emergency managers, commercial users, media outlets (television, radio, social), and the general public. (No change)
NWWS-2 Future Configuration

NWWS chat (Java script)
NWWS products also on
(various formats)
NIDS
Nlets

4. Planned NWWS configuration
NOAA Weather Wire Service (NWWS)
NWWS will be adding to the dissemination streams starting this Fall.
The NWWS will operate similar to the current contractor leased system, with dissemination of weather data via:
C-band satellite (SBN/NOAAPORT Channels and Channel 201 for dedicated NWWS only products)
an Internet-based method known as the "Open Interface," UNDER DEVELOPMENT
the International Justice and Public Safety Network (Nlets), UNDER DEVELOPMENT
NOTE: The “Nlets” system has a private data stream for law enforcement/emergency management networks not open to the general public.
Users of NWWS will be given the opportunity to stay with their current configuration (as CSC remains an NWS client/user) or change to the new/proposed system and interfaces.
 SUMMARY
Current Leased System
Planned NWWS configuration
C-band satellite
(NO CHANGE)
CSC Satellite System
Calypso Receiver
SBN/NOAAPORT NOVRA S300 or similar compatible Receiver and EMWIN Satellites
Internet “Open Interface”
“pull”
(Delivery Change)
Current; Internet via
Spring 2015: XMPP/chat room environment
Text Format(s)
WMO
WMO, CAP v1.1 and CAP v1.2*
Internet Open Interface “push” connectivity
CSC service
NLETS
Planned for Spring 2015
*Common Alert Protocol (CAP) format is for alert text messages only. CAPv1.2 integration is TBD. Only CAP v1.2 is compatible for Emergency Alert System (EAS) activation.

5. C-band satellite Open Interface CSC Satellite Service
No change. (Service is expected to operate into 2015.)
SBN/NOAAPORT Satellite Service
Channels = no change
Channel 201 will require the change identified to the right
Users can continue to re-use the outdoor antennas they already have in place (which will not require re-pointing), but will need 1) a new satellite receiver, 2) new Low Noise Block (LNB) down converter, and 3) new (or modified) weather data display software (NWS End User Client or similar).
EMWIN Satellite Service
(NO CHANGE)
Satellite dish will need repointing. New hardware and software will need to be added.
Open Interface
CSC capability
WMO text products
No change to CSC, Marta, or current display software.
National Weather Service
(NO CHANGE)
All WMO text products (including alerts and warnings) by County
May need to modify or purchase new display software to pull desired products.
National Weather Service
****Alerts and Warnings Only**** RSS and ATOM feeds by State WMO and CAP v1.1 text products
National Weather Service
Open Interface
Will need End User Client (EUC) software or similar

6. Direct socket feed, no change No change to current display software.
NWWS products are also available over the SBN/NOAAPORT (Channels ), Emergency Managers Weather Information Network (EMWIN) satellite product stream and via the NWS Family of Services (all NWS and NWWS products). Family of Services is a NWS for-fee dissemination capability. “Push” Connectivity
CSC capability
Direct socket feed, no change
No change to current display software.
National Weather Service
NO CHANGE
Family of Services (FoS) Option
This is a “for fee” service.
National Weather Service has not determined if there will be a “push” capability in the future.
As NWWS proceeds with the transition, your cooperation, collaboration, and input are appreciated. Please feel free to contact NWS for more information about the upcoming change(s) or to provide input on system capabilities and proposed distribution methods and shortfalls of the available options.
