Subject: Enterprise EMWIN Services Image and Image Archive 
File Availability Issues.

1.  Enterprise EMWIN (eEMWIN) is experiencing image file and image 
    archive file availability issues.

a.  Image Files. Multiple image files have been identified as 
    missing from Virtual Channel 21 on the GOES-East and GOES-West
    HRIT/EMWIN satellite broadcast and FTP Server image archive files. 
    Efforts are underway to isolate and correct this issue. A full 
    listing of the image files and their respective public URLs 
    appears in the 
    "EMWIN_Image_and_Text_Data_Capture_Catalog_v1.3b_r180817" 
    on the NWS EMWIN web page under the Documents tab.  Users are 
    encouraged to use the image URL links to download the missing 
    files until this EMWIN service issue is resolved:

    NWS EMWIN Web Page:
    https://www.weather.gov/emwin/

b.  Image Archive File.  The three-hour image archive file 
    named "imghrs03.zip" on the EMWIN anonymous FTP file server
    is updated at the top of the hour.  The update process has 
    been noted to post in multiple successive increments, as the 
    products are written to the archive file.  If observed over
    time the file may grow in size after the top of the hour.
    The final complete file should post not later than 10 minutes 
    past the top of the hour.  To reduce the possibility of downloading
    an incomplete file, users are encouraged to download the file no 
    earlier than 10 minutes past the top of the hour.

    NWS EMWIN FTP File Server:

Subject: GOES-15 (GOES-West) Satellite Drift to 128-degrees West
Commencing 2015 UTC, October 23, 2018

The GOES-West satellite transition from GOES-15 to GOES-17 is
scheduled to commence at 2015 UTC, October 23, 2018, with the drift
of GOES-15 from 135 to 128-degrees west. The transition is scheduled
to be completed on December 10, 2018, with GOES-17 declared as the
operational GOES-West satellite.

The GOES-15 EMWIN transponder will remain operational throughout the
0.88-degree/day drift to 128-degrees west. Receiving stations with
fixed antenna installations are likely to experience degradation or
loss of signal lock should the satellite move outside the receiving
antenna’s effective beam width. Users should consider incrementally
re-orienting their antennas to maintain an effective signal-to-noise
ratio and signal lock during the GOES-15 drift.

The schedule of events for GOES-15 and GOES-17 is provided below.
Additional details are available from the NESDIS web site:
https://www.goes-r.gov/users/transitionToOperations17.html
 
DATES EVENTS NOTES
----------- ----------------------------- -------------------
OCT23-NOV01 - GOES-15 drift from 135 to - All instruments
  128W and services
    remain operational
OCT24-NOV13 - GOES-17 drift from 89.5 to - HRIT/EMWIN
  137.1W disabled
NOV15 - GOES-17 activated  
DEC10 - GOES-17 declared the  
  Operational GOES-West  
  satellite  

The simultaneous operations of the EMWIN broadcast on
GOES-14(105W) and GOES-15(128W); and the HRIT/EMIWN broadcast on
GOES-16(75.2W) and GOES-17(137.1W) is scheduled to remain in
effect through May 2019.

The close proximity of broadcast frequencies and geosynchronous
orbits of the GOES-15 and GOES-17 satellites may cause EMWIN-15
users to experience interference from GOES-17. Users are
encouraged to make further adjustments in their antenna
orientation to reduce interference issues.

EMWIN virtual channels 20, 21 and 22 on the GOES-16 and 17
HRIT/EMWIN broadcasts will not be operational until 2019.
Users are reminded to use products on the GOES-14 and 15 EMWIN
satellite broadcasts for operations, and to refrain from using
products appearing on channels 20, 21 and 22 in the GOES-16
and 17 HRIT/EMWIN broadcast until declared operational by the NWS.

Subject: GOES-13/14/15/16 Fall 2018 Solar RFI

NESDIS has provided the following information concerning the
potential for outages of the GOES data stream, including EMWIN.

The potential for solar radio frequency interference (RFI) with a
satellite downlink circuit will occur whenever the Sun passes into
the beam of the ground station receiving antenna. The Wallops and
Fairbanks Command and Data Acquisition Stations (CDAs) and
Environmental Satellite Processing Center (ESPC) receiving antennas
may experience periods of Solar RFI as predicted below. Solar RFI
can cause loss of telemetry lock and command capability.

Topic: NOAA Wallops Command & Data Acquisition Station (WCDAS) Facility Power Outage

Date/Time Issued: March 26, 2018 2115 UTC
Product(s) or Data Impacted: All WCDAS data and other operational services
Date/Time of Initial Impact: April 3, 2018 1200 UTC
Date/Time of Expected End: April 5, 2018 2359 UTC
Length of Outage: 48 to 60 Hours

Details/Specifics of Change:

The NOAA Wallops Command and Data Acquisition Station (WCDAS) is planning an entire site power outage on Tuesday, April 3, 2018. The outage is required to perform maintenance and repairs on the station's electrical power system. The power outage can be expected to last as long as three days although the goal is to complete the work within two days.

It is likely there will be an outage of the 1692.7 MHz Emergency Managers Weather Information Network (EMWIN) broadcast for the duration that WCDAS is down for both GOES-14 and 15. If there is an outage, users are asked to utilize GOES-15's LRIT broadcast, the NWS FTP or ByteBlaster services for EMWIN continuity of operations. Additionally, there will not be any NOAA-18 and NOAA-19 HRPT data from WCDAS.

It is not anticipated that dissemination of other data to users will be impacted during this power outage. However, if unforeseen data outages occur, users will be notified as information becomes available.

If a 'Critical Weather Day' is declared, the event will be rescheduled for April 10, 2018.

EMWIN disseminates products over the National Environmental Satellite, Data, and Information Service (NESDIS) GOES-East and GOES-West satellites' HRIT/EMWIN satellite broadcast service. The products are also available in Archived files on an NWS public Internet facing anonymous EMWIN FTP Archive file server.  As products are received from the NWS Telecommunications Gateway and the NOAA Weather Wire Service (NWWS-2), EMWIN first writes the files to the Archive file server and then sends the products over the satellite broadcast.  Should the satellite broadcast become unavailable, the continuous suite of EMWIN products may be downloaded from the Archive file server.
 

Note 1 -- The NWS provides products in unencrypted format on the satellite broadcast (within the HRIT/EMWIN satellite footprint). Users are responsible to purchase and install an HRIT/EMWIN satellite receiver and software to receive, store, and display the products from the broadcast. The EMWIN products are present on the following HRIT/EMWIN broadcast virtual channels:
 

Channel Description  Content
20  EMWIN Priority EMWIN Priority 1 & 2 Text Products*
21 EMWIN Graphics  Image Products
22  EMWIN Other  EMWIN Priority 3 & 4 Text Products*

       
- The priority assigned to text products is documented in the EMWIN Text Product Catalog.

 

EMWIN Archive files are provided in a .zip file format on the anonymous EMWIN FTP Archive file server.  Users must purchase and install a computer with the appropriate software and Internet service to access the Archived files on the server, and "unzip" the products within the EMWIN Archived files.
