NWS Soliciting Comments on Discontinuing EMWIN Internet Feed

NWS is accepting comments until October 24, 2017, on the proposed termination of the EMWIN ByteBlaster and HostMaster services on or about April 30, 2018.

ByteBlaster is a client-server software application which has been implemented in privately developed and commercial software offerings. The NWS operates four ByteBlaster servers as a public service, actively pushing all products appearing on the EMWIN satellite broadcast to users operating a ByteBlaster client or other compatible software over the Internet. Users may connect to the NWS ByteBlaster servers without the approval of, or intervention by, the NWS. HostMaster is a ByteBlaster server load-balancing software application used to manage the clients connected to ByteBlaster servers and automatically transfer connected clients from one known server to another in the event of a server failure.

Weather, water and climate products disseminated by the NWS ByteBlaster service include national and international watches, warnings, advisories, observations, forecasts and remote sensing information in text and picture (binary) formats. As an Internet-based service, ByteBlaster client-server connections can be operated from any location, worldwide, with Internet access.

The NWS is in the process of consolidating its dissemination services into a common architecture. Transitioning ByteBlaster into this new architecture will require significant NWS resources and time. Alternate public Internet-based methods are available for acquiring the products disseminated by ByteBlaster. These alternatives provide users with the opportunity to replace ByteBlaster in their local operations. A sample of these services and their comparative equivalence to ByteBlaster follows:

1. EMWIN File Transfer Protocol (FTP) Archive
- Interface: file pull initiated by user
- Text Products: all text files on EMWIN satellite broadcast, in ZIP file format
- Binary Product: all binary files sent on EMWIN satellite broadcast in ZIP file format
- Reference: click on the link "eEMWIN FTP Service Description draft v0.2 (Draft)," available here:
http://www.nws.noaa.gov/emwin/#documents

2. NOAA Weather Wire Service (NWWS) Operational Interface (OI).
- Interface: automated XMPP file push to registered users (no
fee)
- Text Products:  NWS US weather watches, warnings and advisories; does not include International products and non- weather emergency messages.
- Binary Products: none.
- Reference: http://www.nws.noaa.gov/nwws/

3. Global Telecommunication Service (GTS) Internet File Service
(GIFS)
- Interface:  user initiated web browser Graphical User Interface (GUI) and a command line interface over public Internet
- Text Products: limited to International products for North America, Central America and Caribbean; virtually no US WFO generated products
- Binary Products: none.
- Reference:  click on the "GIFS Open Access RMTN Users Guide"
link here: http://www.nws.noaa.gov/iscs/documents.html
Web browser link:
http://www.nws.noaa.gov/iscs/documents.htmlhttps://ra4-gifs.weather.gov/data/RMTN/

4. All EMWIN binary products may also be obtained by users directly from the web pages accessed by EMWIN, which are documented in the "EMWIN Image and Data Capture Catalog," here:
http://www.nws.noaa.gov/emwin/EMWIN_Image_and_Text_Data_Capture_Catalog_v1.0_r170301-1500a.pdf

The final disposition of the EMWIN ByteBlaster and HostMaster services will be determined after the NWS has reviewed all comments.  NWS will issue a Service Change Notice in the event termination is approved.

Partners and users are encouraged to email comments regarding this proposal to:

Transition of the NWS EMWIN FTP service


The NWS is accepting comments until September 15, 2017, on the proposed transition of the legacy Emergency Managers Weather Information Network (EMWIN) File Transfer Protocol (FTP) service to the NWS Integrated Dissemination Program (IDP) enterprise environment.

The EMWIN FTP file service is transitioning to a new consolidated enterprise infrastructure referred to as IDP.  The new EMWIN IDP FTP service is scheduled to be operational on November 1, 2017. Users of the EMIWN legacy FTP service are encouraged to transition to the new service prior to January 31, 2018, the scheduled date for deactivating the legacy FTP server.

The new EMWIN IDP FTP service provides the following improvements:

-Eliminates the need for users to register for and use assigned user name and passwords to access the EMWIN archive files.  The new EMWIN IDP FTP service is hosted on an anonymous FTP server, providing open public access 24x7, over the public Internet.

-Increases the FTP service operational availability by employing a backup IDP anonymous FTP service that becomes operational in the event of a catastrophic failure of the primary IDP anonymous FTP service.

Two separate and unique sets of EMWIN archive files will be presented on the EMWIN IDP FTP service: one for the older generation GOES-15 satellite (GOES-West) and one for the newer generation GOES-16 satellite (GOES-East). The unique characteristics of their individual satellite broadcast services require separate archives as a result of:

-Different file naming conventions used for the WMO product files appearing on the GOES-West and GOES-East broadcasts. Products on GOES-West retain the legacy EMWIN eight character file name, while the GOES-East will implement the 63 to 66 character WMO compliant file name convention. Additional information on the GOES-East file naming convention is available for review here:


-The maximum data rate on the GOES-West and GOES-East satellite broadcast services will be 19.2 kbps and 256 kbps, respectively.  The higher data rate may periodically deliver a greater number of products in a given time interval, potentially increasing the archive file product count for comparable periods of time.

The NWS EMWIN IDP FTP archive file names and descriptions are:

*** TEXT PRODUCTS ***
txtmin02.zip ....... two minute file
txtmin06.zip ....... six minute file
txtmin20.zip ....... twenty minute file
txthrs01.zip ....... one hour file
txthrs03.zip ....... three hour file

*** BINARY FILES (IMAGES) ***
imgmin15.zip ....... fifteen minute file
imghrs01.zip ....... one hour file
imghrs03.zip ....... three hour file

Additional information on the new IDP anonymous FTP service and files is found in the Enterprise EMWIN FTP Service Description document available here:


A Service Change Notice (SCN) will be sent before transitioning operations to the new EMWIN IDP FTP service.

Questions or comments about this service should be emailed to:

EMWIN GOES-East satellite broadcast signal and file format changes effective November 2017


Effective in November 2017, the National Environmental Satellite, Data, and Information Service (NESDIS) Geostationary Operational Environmental Satellite (GOES)-16 will replace the existing operational GOES-13 at the GOES-East geosynchronous orbit location of 75 degrees west longitude. The GOES-East location assignment was announced by NESDIS on May 25, 2017. The specific date and time in November for the replacement has not been announced. An updated Service Change Notice will be sent when the date is determined.

The NWS and NESDIS hosted two public Webinars in April and August 2016 to identify and review the changes to the Emergency Managers Weather Information Network (EMWIN) broadcasts with the introduction of GOES-16. The Webinars also included time to receive and respond to participant questions and comments regarding these changes. Participants included individual users, emergency managers, third party emergency alert service providers, media outlets and hardware and software manufacturers. The presentations provided at these Webinars are available here:


The operational deployment of GOES-16 introduces three changes to the GOES-East EMWIN broadcast impacting the reception and decoding of products in the High Rate Information Transmission (HRIT)/EMWIN L-band satellite broadcast data stream, as follows:

-HRIT/EMWIN Receiver: GOES-16 broadcasts the EMWIN and the NESDIS HRIT data streams over a single transponder in a combined HRIT/EMWIN format. EMWIN receive stations will need to be updated with an HRIT/EMWIN receiver and antenna system to receive and decode the EMWIN data stream from the HRIT/EMWIN broadcast.

-Full-File Format: The products on the EMWIN segment of the GOES-16 HRIT/EMWIN broadcast are sent as complete files, in contrast to the Quick Block Transfer (QBT) packet format employed on the GOES-13 EMWIN broadcast. Software updates may be required to properly handle this new full-file format.

-File Name Change: The file name assigned to each of the full- file products on the EMWIN segment of the HRIT/EMWIN broadcast will contain 63 to 66 alpha-numeric characters followed by a period and a three character file extension. The new file name convention is online at:


The GOES-16 satellite is now in orbit at a service check-out location (89.5 degrees west longitude) until November 2017.  The satellite's HRIT/EMWIN transponder is active but may periodically be taken off line to accommodate other spacecraft events. Users are encouraged to install and verify the operations of new or updated HRIT/EMWIN receive equipment and software. The HRIT/EMWIN broadcast should not be used for operations until GOES-16 is declared operational in November 2017.

Questions or comments regarding these changes may be emailed to the NWS EMWIN support staff at:  nws.emwin.support@noaa.gov.

Manufacturer and User Feedback During the HRIT/EMWIN PLT



We are still on track for to a two-part post-launch test or PLT of HRIT/EMWIN. We will do the first part from the CBU on June 6-8 (where there will be CMI imagery for 23 hrs June 6-7 and all other products the whole time) and [b] from WCDAS on June 13 -15 with a more or less full suite of data content including the CMI imagery.

To make this test "successful", we would like to get some feedback from our partners, manufacturer community and users. We would like to receive relevant metrics and feedback during and after the test periods. A draft list of input is below. Please let me know if you would like to participate either formally with a report or with anecdotal testimony. If you are uncomfortable with any aspect of the list below, let me know what you can perform. Please pass this on to anyone else you may know about and ask them to contact me if they are interested.

I am especially interested in the usability of the CMI imagery and the EMWIN file-based data which is a large change from the GOES-NOP format.

Paul

Pre-test: 
o   Confirm readiness to receive HRIT signal, and provide point of contact info
o   Provide info on receiver model and software to be used. 
o   Provide info on the antenna size at your installation
o   Identify which products will be ingested and evaluated. 
o   Prepare to provide quantitative and qualitative feedback, such as:  
counts of products received/ingested per type per time interval
reports of anomalies (time-tagged)
·         
During test: 
o   Confirm broadcast "lock" and quality of signal
o Monitor broadcast reception; collect metrics on HRIT from user system perspective
o   Spot-check readability and usability of products (indicate what times looked at).  o Report anomalies or other immediate feedback to HRIT POC, as appropriate

After each test: 
o   Follow-up on any discrepancies observed or
o   As appropriate, sample/compare products received via HRIT to quality of same available from another source.
o   Send summary feedback and metrics for each test period.

GOES-16 set to become GOES-EAST in November

GOES-16, the most advanced weather satellite NOAA has ever developed, will be moved to the GOES-East position once it is declared operational in November.  NOAA officials announced the decision regarding GOES-16’s placement, during the 2017 Atlantic Hurricane Season Outlook news conference at NOAA’s Center for Weather and Climate Prediction in College Park, Maryland.

When GOES-16 takes over, EMWIN-N users will need to point their dishes to GOES-West to receive the EMWIN-N signal.  GOES-16 will replace the EMWIN-N signal with HRIT/EMWIN.  HRIT/EMWIN uses a different signaling method and will require a new receiver.

See this link for more information on this announcement GOES-16.
