Legacy EMWIN Service Termination effective December 2, 2019

The NWS Legacy EMWIN services will terminate effective 1700Z December 2, 2019.  The individual
services include:

-EMWIN Satellite Broadcast Service (1692.7 MHz, GOES-14/15)
-EMWIN File Transfer Protocol (FTP) archive file server
-EMWIN ByteBlaster and HostMaster public Internet dissemination services at NWS Headquarters

On August 29, 2019, the NWS follow-on enterprise EMWIN (eEMWIN) services were placed into operations

following the release of a public notification issued on August 29, 2019, via Service Change Notice:



https://www.weather.gov/media/notification/scn19-53emwin_goesaab.pdf



The new eEMWIN services consist of:



-eEMWIN satellite broadcast service on the NESDIS GOES-East and GOES-West HRIT/EMWIN Broadcast
(1694.1 MHz, GOES-16/17)



-eEMWIN anonymous FTP archive file server

NWS will provide more than 90 days of parallel operations of the legacy EMWIN services and the
updated eEMWIN services before terminating the legacy EMWIN services on December 2, 2019. This
overlap should provide users the opportunity to acquire, install, operate and transition to the new
HRIT/EMWIN receiving system and software, with minimal impact to current operations.

The following NWS Internet-based resources are available for acquiring the products provided by
Legacy EMWIN ByteBlaster.

a. NOAA Weather Wire Service (NWWS) Operational Interface (OI): public Internet file push service.
The reference web page for this is: www.nws.noaa.gov/nwws/

Weather Wire Transition

NWS will be transitioning NWWS-OI services from primary to backup on September 9, 2019.  Based on corrections to NWS systems during the last transition, no action should be required; i.e., all accounts should automatically transition over with only a slight delay.  If your system should fail, the backup IP address is 140.90.113.240.  Check the NWWS webpage for additional information.

A return transition from backup to primary is planned for September 11, 2019.

                  Operations for GOES-East and GOES-West Satellite
                  Broadcasts Effective on a date to be determined (TBD)

Updated to reflect the effective date of the eEMWIN services becoming operational from July 24, 2019 to TBD; an updated SCN will be issue when a new date is set.

Effective on a date to be determined, the NWS enterprise Emergency Managers Weather Information Network (eEMWIN) service is scheduled to transition to an operational NCEP Central Operations Integrated Dissemination Program (IDP) platform.  The eEMWIN dissemination service operates through a public facing NWS web service and over the National Environmental Satellite, Data, and Information Service (NESDIS) Geostationary Operational Environmental Satellite R (GOES-R) Series satellites. The present operational GOES-R Series satellites are:

GOES-East (GOES-16) at 75.2 degrees West longitude GOES-West (GOES-17) at 137.2 degrees West longitude

HRIT-EMWIN SERVICE PHASE-IN

On July 30, 2019, the NWS eEMWIN service enters a 30-day system stability evaluation period.  On a date to be determined, after a successful evaluation period, the NWS eEMWIN HRIT-EMWIN broadcast and public facing NWS web service will be operational.

Users transitioning to the High Rate Information Transmission
(HRIT) EMWIN broadcast service will require an HRIT-EMWIN receiving station.  HRIT-EMWIN system requirements and user information are available from NESDIS. Some information on HRIT- EMWIN receiving station equipment available for purchase is provided on the NWS EMWIN Web Services:

 https://www.nws.noaa.gov/emwin/#hrit-emwin
