    This message is informational only, it has no bearing on the operational GOES-East and GOES-West HRIT/EMWIN Broadcasts.

    During the annual GOES-17 checkout, the HRIT/EMWIN transponder is on and we have been testing a draft modification to the file format used by HRIT/EMWIN to disseminate DCS data. The DCS Program is developing a binary DCP message format for more efficient use of their available uplink bandwidth. Microcom has been implementing the capability in parts of the ground system, including in the DCS-HRIT file creation for data delivery to PDA and HRIT/EMWIN. There is no imminent change coming to the operational HRIT/EMWIN broadcast.

    If you're interested in reading a draft format specification of new DCS-HRIT data files, and inspecting sample data files, they are available on the DCS Program webservers:

    1. Draft Revision 2 of the HRIT-DCS file format specification ('Rev2") is available on the NOAA DCS webserver (https://dcs1.noaa.gov ... https://dcs4.noaa.gov) under 'System Information' -> 'HRIT Information' -> 'HRIT File Format Specifications Rev2 (PDF)' dated May 2026
    2. Four sample HRIT-DCS data files are available in the same section dated May 2026. An explanatory text file, ' HRIT File Message Summary' is a formatted ASCII dump of the example files.

    If you're interested in receiving such files on the GOES-17 HRIT/EMWIN Broadcast, we plan to send a selection of them mixed among standard-format data files in Virtual Channel 32 on Monday 8 June 10:00--16:00 EDT (subject to change). Note that Microcom DigiRIT receivers may flag some messages as having errors, and we do not know how other receiver types' software will handle the files.

    GOES-17 is at 89.5 deg W longitude and drifts north-south +- 1 deg off the equator over 24h, due to relaxed station-keeping during storage.

    Last fall, the Administrator of the United States National Telecommunications and Information Administration (NTIA) announced NTIA’s intention to recommend that the Federal Communications Commission (FCC) auction 1675-1680 MHz, a section of spectrum commonly referred to as L-band. This is in response to the spectrum pipeline provisions of a US law, H.R.-1, "The Big Beautiful Bill Act". This law called on the NTIA to identify 500 MHz of federally allocated spectrum for auction. Additionally, the 1680-1695 MHz band was identified as an area for further Federal reallocation. DCS, HRIT/EMWIN, and GRB users should note the potential sharing or public auction of L-band spectrum from 1675MHz to 1695MHz because this spectrum is currently used for NOAA hemispheric broadcasts for GOES DCS, HRIT/EMWIN, and Global Rebroadcast (GRB). It is also spectrum allocated for the DCS hemispheric broadcast aboard GeoXO starting in approximately 2032.

    The NTIA has now published a letter announcing a feasibility study to repurpose the L-band spectrum for commercial use, "..including the potential for identifying the full 1675-1695 MHz band for auction."
    https://www.ntia.gov/sites/default/files/2026-03/1675-mhz-identification-letter.pdf

    The HRIT/EMWIN and GRB Programs anticipate that government studies for spectrum reallocation will request information from us on how these potential changes will affect NOAA and other organizations. Studies may include requests to identify the numbers and locations of users that rely on L-band direct reception. To prepare for these questions the Programs would like to offer a method to improve communication and consolidate information on L-band direct receive systems. The DCS Administration and Data Distribution System (DADDS) has a Direct Readout (DRO) database available for users to communicate the location of receivers and the data types/services received.

    Interested users can volunteer this information online using the DADDS website at one of the following links: https://dcs1.noaa.gov
    https://dcs2.noaa.gov
    https://dcs3.noaa.gov
    https://dcs4.noaa.gov

    A login is not required. At the bottom of the webpage, click the text that states: "Help us keep you up to date with changes and anomalies!" to open the DRO registration page. Providing updated direct receive information will help NOAA develop a better awareness of L-band receiver use and impact. The current system limits registrations to one per e-mail address. If necessary, please use an alternate email address; we apologize for the inconvenience.

  4. Effective 2022/06/30

    Topic: Notification of Upcoming Orbit Location Maneuvers of GOES-17 and GOES-18
    Date/Time Issued: June 30, 2022 1931 UTC
    Product(s) or Data Impacted: None
    Date/Time of Initial Impact: July 5, 2022 at 15:57 UTC for GOES 17 and July 5, 2022 at 16:54 UTC for GOES-18
    Date/Time of Expected End: July 16, 2022 at TBD time for GOES-17 and July 20, 2022 at TBD time for GOES-18 Length of Event/Outage: N/A

    Details/Specifics of Change:

    NOAA will be repositioning GOES-17 and GOES-18 with synchronized burns to maintain a longitude separation of 0.3 degrees for RFI avoidance during drift and while on-station. These are both slow rate location “nudges”, as opposed to nominal drifts which are faster and cause a disruption to data availability.  Start burns will be executed July 5th and both will utilize natural drift to stop at their new stations.

     

    GOES-17 nudge start at 137.2W on July 5th at 15:57 UTC
    GOES-17 nudge stop at 137.3W on July 16th at TBD time
    GOES-18 nudge start at 136.8W on July 5th at 16:54 UTC
    GOES-18 nudge stop at 137.0W on July 20th at TBD time

     

    There are no anticipated L-band downlink impacts for GOES-17 GRB, HRIT/EMWIN and DCS users regarding the 0.1 degree westward longitudinal drift.  Antennas smaller than 7m should not need to repoint.  Antennas larger than 7m should repoint.Users are reminded to peak their antennas after the nudge periods end in order to achieve the best optimal signal.

    Administrative: Update #2: GOES-18 Interleaving Test June 14, 2022, Issued: June 8, 2022 1348 UTC

    Update#2: This is a reminder that the GOES-18 Interleaving Test will occur on June 14, 2022 from 1600-2000 UTC

    Update #1: The date for the GOES-18 interleave test has changed from June 15th to June 14th

    Topic: GOES-18 Interleaving Test June 14, 2022
    Date/Time Issued: June 8, 2022 1348 UTC
    Product(s) or Data Impacted: GOES-17 (GOES-West) ABI, GLM, Space Weather
    Date/Time of Initial Impact: June 14, 2022 1600 UTC
    Date/Time of Expected End: June 14, 2022 2000 UTC
    Length of Outage: 4 hours
    Details/Specifics of Change:

    On June 14, 2022 at 1600 UTC, a four hour test of the interleave configuration will be performed on the GOES-17 (GOES-West). This test is a user readiness opportunity to prepare for the operational interleave configurations that will be in place 24 hours per day during the two periods of August 1 - September 6 and October 15 - November 11, 2022.

    At the time of the interleave test, GOES-18 will be located in a near-West orbital slot (136.8 degrees West), just 0.4 degrees from GOES-17 (at 137.2 degrees West).

    The interleave configuration entails populating the operational GOES-17 GRB (GOES Rebroadcast) service with an “interleave” of GOES-18 ABI data (replacing the GOES-17 ABI data) and GOES-17 GLM and space weather data. See this table for the key to GRB Spacecraft IDs and Metadata: https://www.ospo.noaa.gov/Operations/GOES/documents/GRB%20Interleave%20Spacecraft%20ID's%20and%20Metadata.pdf

    In order to ensure continuity of GOES-West ABI operations, GRB users are advised to ensure their end-processing will accept a different ABI platform ID (G18 rather than G17) and instrument ID (FM3 rather than FM2). More information on global attributes is available in the Product User’s Guide (PUG) Volume 4 for GRB: https://www.goes-r.gov/users/docs/PUG-GRB-vol4.pdf

    Here is the GOES-West data content of each product distribution service during interleave:

    GRB: (netCDF file orbital slot will be "GOES West")
    - G18 ABI L1b
    - G17 GLM L2+
    - G17 Space Wx L1b

    PDA: ("GOES West" for products below)
    - G18 ABI L1b, CMI (no L2+)
    - G17 ABI L1b, CMI, L2+
    - G17 GLM L1b, L2+
    - G17 Space Wx L1b

    - Note PDA cal/val subscriptions have additional G18 data access

    CLASS:
    - G17 ABI L1b, CMI, L2+
    - G17 GLM L1b, L2+
    - G17 Space Wx L1b

    Note CLASS cal/val subscriptions have additional G18 data access

    NODD (formerly BDP):
    - G18 ABI Rad, CMI
    - G17 ABI Rad, CMI, L2+
    - G17 GLM L2+
    - G17 Space Wx L1b

    HRIT/EMWIN:
    - G18 ABI CMI
    - G17 ABI L2+

    GNC-A:
    - G18 ABI CMI

    AWIPS:
    - G18 ABI SCMI
    - G17 GLM L2+

    During the June 14th test, GOES-18 ABI data will still be at a “Beta” level of maturity, minimally validated, and may contain significant errors. Nonetheless, GOES-18 ABI data obtained during this test will be advised for operational use, and may be shared without restriction.

    During the Aug-Sep and Oct-Nov interleave periods, GOES-18 ABI data will be at “Provisional” level of maturity, fit for operational use and may be shared without restriction.

    This test is subject to delay in the event of a Critical Weather Day declaration.

    Note regarding GOES-17 ABI during interleave: GOES-17 ABI will be operating continuously until the GOES-West transition from GOES-17 to GOES-18 in January, 2023. Continuous GOES-17 ABI operations will include the June 14th interleave test and the Aug-Sep and Oct-Nov interleave periods when GOES-17 ABI will have multiple focal plane module temperature (FPM) mitigations including the cooling timeline and multiple FPM set points adjustments.

    		SUBJECT:	Seeking Comments on Proposed Changes to User Access of NCEP Web Services through December 18, 2020
    		The NWS National Centers for Environmental Prediction (NCEP) is seeking public comments through December 18, 2020,
    		on the management of user access of the NCEP Web Services.
    
    		As demand for data continues to grow across NCEP websites, we are proposing to put new limits into place to
    		safeguardour web services. The frequency of how often these websites are accessed by the public has created
    		limitations and infrastructure constraints. To add new or upgraded streams of data, there has to be a reduction
    		in the number of connections into our system. The mitigation will reduce the strain on our infrastructure, ensuring
    		a more robust level of service for all users.
    
    		For example, a possible mitigation would lower the limit of the number of connections to 60 per minute for a given
    		user accessing any of the websites below. This would be a cumulative limit for any type of data request across any
    		website. A "head" request will count towards the limit the same as a "get" request.
    
    		Websites affected, both ftp and https, would include:

    		NWS is collecting comments through October 30, 2020, on proposed changes to its Tsunami Advisory products.
    		This proposal is part of the broader Hazard Simplification effort within NWS.
    
    		NWS currently issues Tsunami Advisory products to alert stakeholders to lower-magnitude tsunami events
    		that may pose a danger to coastal communities. In some situations, Tsunami Advisory products may be
    		misunderstood in terms of their expected impacts to coastal populations, along with the associated
    		protective actions that need to be taken. It is proposed that a new way of communicating the exact
    		nature of the danger may reduce some of the confusion surrounding these lower-magnitude products.
    		Therefore, the NWS is soliciting comments on potential new product options as follows:
    
    		Option A: Tsunami Warning for Strong Currents [with Tsunami in Header]
    		Option B: Harbor and Beach Warning [without Tsunami in Header]
    		Option C: Harbor and Beach Tsunami Warning [with Tsunami in Header]
    
    		Please see the NWS Product Description Document (PDD) for more details:
    		https://nws.weather.gov/products/PDD/PDD_Tsunami_Advisory_Products_for_HazSimp_2020-9-25-20.pdf

    		https://www.surveymonkey.com/r/tsunamiadvisory
    		En español: https://www.surveymonkey.com/r/SpanishTsunami
    
    		Based on feedback received, NWS may implement this new product language and text format.

    		Asunto: Se solicitan comentarios hasta el 30 de Octubre de 2020 para posibles cambios en el texto de los
    		formatos de los productos de Advertencia de Tsunami.
    
    		El Servicio Nacional de Meteorología está recopilando comentarios hasta el
    		30 de Octubre de 2020 sobre los cambios propuestos en sus productos de Advertencia de Tsunami. Esta propuesta
    		forma parte del esfuerzo más amplio de Simplificación de Riesgos dentro del SNM.
    
    		Actualmente, el SNM emite productos de Advertencia de tsunami para alertar a las partes interesadas sobre eventos
    		de tsunami de menor categoría que pueden representar un peligro para las comunidades costeras. En algunas
    		situaciones, los productos de Advertencia pueden ser malinterpretados en cuanto a lo que el nivel de Advertencia
    		significa para las poblaciones costeras, y las acciones que deben seguir. Se propone que una nueva forma de
    		identificar el peligro, pueda reducir parte de la confusión que rodea a estos productos de categoría inferior.
    		Por lo tanto, el SNM está solicitando comentarios sobre posibles opciones de nuevos productos de la siguiente
    		manera:
    
    		Opción A:
    		Advertencia de Tsunami para Corrientes Fuertes [con encabezado de Tsunami]
    		Opción B:
    		Advertencia de Puerto y Playa [sin encabezado de Tsunami]

    Topic: GOES-14/15/16/17 Fall 2020 Solar RFI predicted times are now available

    Date/Time Issued: September 29, 2020 1522 UTC

    Product(s) or Data Impacted: GOES-14/15/16/17 Imager Data plus Ancillary Services (GVAR, SAR, LRIT, EMWIN, DCS, GRB, etc.)

    Date/Time of Initial Impact: October 3, 2020 1642 UTC

    Date/Time of Expected End: October 17, 2020 2129 UTC

    Length of Outage: See table in details.

     

    Details/Specifics of Change: 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.

    We received the following information from our Mission Operations Division concerning the potential for outages of the GOES data stream including GVAR (GOES Variable) Imager and Sounder, EMWIN (Emergency Managers Weather Information Network), SAR (Search and Rescue), Low Rate Information Transmission (LRIT), High Rate Information Transmission (HRIT), GOES Data Collection System (DCS), Sensor Data (SD), Telemetry and Command (T&C), Weather Facsimile (WEFAX), Data Collection Platform Report (DCPR), Multi-use data link (MDL), Raw Data Link (RDL), etc.

    The Dongara 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, as well as degradation or loss in the GVAR data.

    		Subject: Soliciting comments through October 30, 2020 for potential changes to Tsunami Advisory text product
    		formats.
    
    		The NWS is collecting comments through October 30, 2020, on proposed changes to its Tsunami Advisory products.
    		This proposal is part of the broader Hazard Simplification effort within NWS.
    		NWS currently issues Tsunami Advisory products to alert stakeholders to lower magnitude tsunami events that
    		may pose a danger to coastal communities.  In some situations, Tsunami Advisory products may be misunderstood
    		in terms of their expected impacts to coastal populations, along with the associated protective actions that
    		need to be taken. It is proposed that a new way of communicating the exact nature of the danger may reduce
    		some of the confusion surrounding these lower-magnitude products.  Therefore, the NWS is soliciting comments on
    		potential new product options as follows:
    
    		Option A:  Tsunami Warning for Strong Currents [with Tsunami in Header]
    		Option B:  Harbor and Beach Warning [without Tsunami in Header]
    		Option C:  Harbor and Beach Tsunami Warning [with Tsunami in Header]
    
    		Please see the NWS Product Description Document (PDD) for more details:
    		https://nws.weather.gov/products/PDD/PDD_TsunamiAdvisoryProducts_HazSimp_2020.pdf
    
    		Feedback concerning these options can be provided using the following link:
    		https://www.surveymonkey.com/r/tsunamiadvisory
    
    		Based on feedback received, NWS may implement this new product language and text format.

    		Subject: Seeking comments through August 2, 2020on on proposed replacement
    				 of RIDGE I radar webpage with RIDGE II radar webpage
    
    		NWS is proposed to replace the Radar Integrated Display with Geospatial Elements
    		(RIDGE) Radar Version I webpage with the Version lI webpage. NWS is soliciting
    		comments on the proposed RIDGE II radar webpage through August 2, 2020.
    
    		RIDGE I operational URL: https://radar.weather.gov
    		RIDGE II preview URL**:  https://preview-radar.weather.gov/
    		**At this time the URL is currently only intended for users to provide feedback. Users
    		should not set up operational feeds from it.
    
    		The RIDGE Version II would replace RIDGE Version I of FLASH with HTML5 and
    		Javascript with a web-based and mobile-friendly display that uses Multi-Radar
    		MultiSensor (MRMS) datasets on an interactive map containing Open Geospatial
    		Consortium (OGC) compliant layers. Along with the included radar products, users
    		would also have the ability to display NWS long- and short-fused Watches, Warnings,
    		and Advisories.
    
    		The web map is optimized for small and large screen devices. Users can bookmark a
    		particular perspective of the map or select and save the perspective of a particular
    		radar. As a result, there would no longer be a need for the individual web pages that
    		display specific Weather Surveillance Radar-1988 Doppler (WSR-88D) products. These
    		webpages (ex. https://radar.weather.gov/radar.php?rid=aaa; where ‘aaa’ is the 3-letter
    		identifier of the radar) will be discontinued along with RIDGE I.
    
    		For further details, please see the Product Description Document:
    		https://nws.weather.gov/products/PDD/PDD_ExpRidgeII_2020.pdf
    
    		The preview geoTIF images can be accessed at:
    		https://mrmst.ncep.noaa.gov/data/RIDGEII/
    
    		If approved for replacement, the NWS will issue a Service Change Notice (SCN)
    		detailing when the RIDGE II webpage will be supported operationally. The SCN would
    		also specify the transition period from RIDGE I to RIDGE II. At that point, the current
    		RIDGE I webpage (https://radar.weather.gov) would run in-parallel with the new RIDGE
    		II webpage for 75 days to enable users to transition to RIDGE II. At the end of the 75
    		days RIDGE II will replace RIDGE I.
    		The NWS will evaluate all comments during this period and will determine any additional
    		and immediate need for changes, based on public feedback. Please provide feedback
    		through the NWS survey at:

    		The NWS is considering a major change to the Watch, Warning and Advisory (WWA) system
    		(for information on this and other proposed changes, see: https://www.weather.gov/hazardsimplification/.
    
    		The proposed new system would remove the terms "Advisory," "Special Weather Statement," and "NOWcast" as
    		headlines, and streamline all subWatch and sub-Warning information into a single, plain-language Statement,
    		with a few exceptions.  One exception to this change includes the marine Small Craft Advisory (SCA), one
    		of the advisories included in the Marine Weather Message (MWW) product and the Coastal Waters Forecast (CWF)
    		product.
    
    		Due to the critical nature and use of the information of the Small Craft Advisory and that associated conditions
    		 require vessels of a certain size to take protective action, NWS proposes to rename this advisory to Small Craft
    		Warning instead of converting it to a plain-language statement.  The NWS regional criteria for issuing Small Craft
    		Warnings would remain the same as it is for Small Craft Advisories.
    
    		Here is a link to the current regional SCA criteria: https://www.weather.gov/marine/faq#13
    
    		At this time, the NWS is soliciting specific feedback on the proposal to change a Small Craft Advisory to a Small
    		Craft Warning, including the headlines.

    				   Warning, and Advisory (WWA) system.
    
    		As the core outcome of the Hazard Simplification (Haz Simp) project, the NWS is collecting comments
    		through August 21, 2020, on the proposed discontinuation of "Advisory, "
    		"Special Weather Statement, " and "Short Term Forecast" headlines. In their place,
    		NWS proposes the use of generic, plain language statements to convey information for lower-level
    		hazardous events that are not expected to reach the “Watch” or "Warning" levels.
    		All current "Watch" and "Warning" products, used to highlight hazards that pose a
    		threat to life and property, would remain unchanged.
    
    		The purpose of this proposal is to address extensive social science research, which indicated three
    		main concerns:
    
    		1) Large number of existing WWA products can create confusion for NWS partners and the public
    		2) Formats of WWA and other key messaging products are inconsistent
    		3) WWA headlines can be misunderstood, leading to unintended protective action or lack thereof.
    
    		More details on this proposal, along with a library of examples showing how current messages would
    		transition to plain language statements, can be found in the Product Description Document (PDD):

    		are accessed and used during high-impact events.
    
    		There are three specific target sectors for this survey:
    		(1) Users who communicate the information from NWS tropical products directly to the
    			public,
    		(2) Emergency management officials that use information from NWS tropical products to
    			make and message public safety decisions, and
    		(3) Those who repackage the information from the NWS tropical products primarily
    			through parsing (i.e., the use of software or other tools to automatically process
    			products to extract all or parts of the product).
    
    		The survey is available at the following link and will remain open until June 30, 2021:
    
    		https://www.surveymonkey.com/r/NWSTropicalProducts
    
    		The NWS Hurricane Harvey Service Assessment Finding 2 stated “...local tropical
    		products were not widely used by the media and other core partners during Hurricane
    		Harvey.” The assessment goes on to recommend that “Local offices, Regional
    		Headquarters, and the NWS Tropical Program should determine whether partners’ lack
    		of use of local tropical products was peculiar to Hurricane Harvey or represents a
    		broader condition affecting other coastal areas.” The Hurricane Harvey NWS Service
    		Assessment can be found here:
    
    		https://www.weather.gov/media/publications/assessments/harvey6-18.pdf
    
    		The results of this survey will be used to gain a general understanding of how specific
    		partner sectors use and access NWS tropical products, and to make an informed
    		decision on specific changes that may be needed to ensure the products are effective
    		and meeting partners’ needs. Proposed changes to NWS products/services will be open
    		for broader public comment before implementation.
    
    		The NWS Tropical Services Program provides programmatic leadership for the nation‘s
    		tropical weather program, which includes operations at the National Hurricane Center
    		(NHC), the Central Pacific Hurricane Center (CPHC), and NWS Weather Forecast
    		Offices (WFOs). Please send comments and questions regarding this survey to the

    				-NOAAPort
    				 Other NWS Partners and NWS Employees
    
    		From:    Eli Jacks Chief, Forecast Services Division
    		Subject: Announcing partner webinars in June and July 2020, on
    				 proposed major changes to the NWS Watch, Warning and
    				 Advisory (WWA) system
    
    		Over the past 6 years, the NWS Hazard Simplification (Haz Simp)
    		Project has use a series of social science engagements with
    		forecasters, core partners, and other stakeholders to explore
    		possible improvements to the NWS Watch, Warning and Advisory
    		(WWA) system. This research found users believe there are too
    		many WWA products, message formats are inconsistent, and WWA
    		headlines can be confusing. In particular, the "Advisory"
    		headline was found to be widely misunderstood and even conflated
    		with "Watch".
    
    		Based on these results, the Haz Simp Team has developed a
    		proposal to streamline and simplify the WWA system. A 1-page
    		handout summarizing the proposed changes is available for
    		download here:
    
    		
    		https://www.weather.gov/media/notification/ref/Hazard_Simplification_Proposal.pdf
    
    		All NWS partners and stakeholders (including but not limited to
    		emergency managers, media and other private sector partners,
    		first responders, DOT personnel, water managers, and other
    		federal, state, and local government and tribal officials) are
    		invited to attend a Partner Webinar to learn about the proposed
    		changes and offer feedback.
    
    		There are 5 interactive webinars to choose from, each of which
    		will cover the same material:

    		The proposed changes have not been finalized. Our decision will
    		be heavily based on user feedback, which makes wide
    		participation in these webinars so important.
    
    		While these webinars are for NWS partners, NWS will also solicit
    		comments/feedback from the general public regarding this
    		proposal. More information on this process will be released via
    		a separate Public Information Statement in the coming weeks.

    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

    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.

    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.

    SUBJ: "EMWIN SERVICES TRANSITION - 2016/2017" WEBINAR

    ESTEEMED COLLEAGUES:

    GOES-R, THE NEXT GENERATION OF NESDIS GOES SATELLITES, IS SCHEDULED FOR LAUNCH IN OCTOBER 2016 AND SHOULD BECOME OPERATIONAL IN BY OCTOBER 2017. EMWIN DATA, NESDIS IMAGERY AND GOES DATA COLLECTION SYSTEM /DCS/ DATA WILL BE TRANSMITTED TOGETHER OVER THE GOES-R HRIT/EMWIN TRANSPONDER AT 400KBPS. THE INCREASED BANDWIDTH IS EXPECTED TO IMPROVE THE THROUGHPUT OF THE EMWIN DATA STREAM. THE NEW SERVICE WILL REQUIRE NEW RECEIVER HARDWARE AS THERE WILL BE A RECEIVER FREQUENCY SHIFT TO 1694.1 MHZ, FROM 1692.7 MHZ /EMWIN/ AND 1691.0 /LRIT/ AND A CHANGE IN MODULATION FOR EMWIN USERS. A NEW ANTENNA OR ANTENNA COMPONENTS MAY ALSO BE REQUIRED.

    THE EMWIN DATA WILL BE BROADCAST AS COMPLETE FILES OVER THE HRIT/EMWIN CHANNEL, WHICH IS A DEPARTURE FROM THE PRESENT EMWIN PACKET STREAMING FORMAT. THE EMWIN FILE NAMES WILL ALSO CHANGE FROM THE EXISTING 12 CHARACTER FORMAT, TO A MORE LENGTHY WMO COMPLIANT FORMAT. THE EMWIN EIGHT CHARACTER FILES NAMES CURRENTLY IN USE WILL BE INCLUDED IN THE NEW FILE NAMES, TO ASSIST CURRENT USERS WITH PRODUCT IDENTIFICATION.

    THE DECISION TO PLACE THE GOES-R SATELLITE AT THE EAST /75-DEGREES W/ OR WEST /137-DEGREES W/ LOCATION HAS NOT YET BEEN MADE. A DATE FOR THE DECISION HAS NOT BEEN ANNOUNCED.

    THE NWS WILL BE HOSTING AND ONLINE WEBINAR AT 1400 EDT / 1800 UTC, ON APRIL 14, 2016, TO IDENTIFY AND REVIEW THE UPCOMING CHANGES TO EMWIN SERVICES. GENERAL REGISTRATION FOR THE WEBINAR IS AVAILABLE ON THE FOLLOWING LINKS:

    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.
