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:

SUBJECT: National Tsunami Warning Center Routine Communications
Tests for the West Coast and Alaska Coast to take place
on November 13, 2020

The NWS National Tsunami Warning Center (NTWC) and coastal NWS Weather Forecast Offices (WFO) will perform routine 
monthly tsunami communication tests to ensure end-to-end readiness of NWS dissemination software and hardware on 
Friday, November 13, 2020, for Alaska and West Coast states.

The intended recipients of these communication tests include designated national focal points, state/territorial 
warning points, coastal WFOs, U.S. Coast Guard, and critical military dissemination points.

Each test message will be clearly identified as such, and will be consistent with the product changes implemented 
by Service Change Notice 18-94: Changes to Valid Time Event Codes (VTEC) and Event Tracking Numbers (ETN) for 
Domestic Tsunami Test Products Effective April 1, 2019.

https://www.weather.gov/media/notification/pdfs/scn18-94vtec_tsunami.pdf

VTEC codes for the test messages will start with the /T fixed identifier (versus /O for operational messages). 
To provide additional assurance that a test message is not inadvertently distributed as an actual 
Warning/Advisory/Watch product, Event Tracking Numbers (ETN) for the test messages will begin with 9 as the 
leading digit of the four character code.

The text products affected by routine monthly tsunami communication testing are the national tsunami products 
issued under the following AWIPS Product Identifiers (PIL) and World Meteorological Organization (WMO) Identifiers 
(ID):

NTWC Product AWIPS PIL WMO ID
------------ --------- ------
Segmented Tsunami W/W/A TSUWCA WEPA41 for West Coast/BC/Alaska

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:

De: Allison Allen
Jefa, Marina SNM, Tropical, y Subdivisión de Servicios de Tsunami

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]
Opción C:
Advertencia de Puerto y Playa [con encabezado de Tsunami]

Consulte el Documento de Descripción del Producto (PDD por sus siglas en inglés) del SNM, para obtener más detalles:
https://nws.weather.gov/products/PDD/PDD_Tsunami_Advisory_Products_for_HazSimp_2020-9-25-20.pdf

Puede emitir sus comentarios sobre estas opciones utilizando el siguiente enlace:
https://www.surveymonkey.com/r/SpanishTsunami

Basado en los comentarios que se reciban, el SNM podrá implementar este nuevo lenguaje de productos y el 
formato de texto.

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:
https://www.surveymonkey.com/r/ProposedRidge2

Subject:          Updated: Soliciting Comments on Proposal to Change           
                  Small Craft Advisory to Small Craft Warning through
                  August 31, 2020

                  Updated to extend deadline to August 31, 2020. 

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.

A description of the proposal to change Small Craft Advisory to Small Craft Warning, product examples, 
and requirements explanation can be found at the following link:

Subject:   Soliciting comments through August 21, 2020, on proposed major changes to the NWS Watch, 
           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): 

https://nws.weather.gov/products/PDD/PDD_Proposed_FinalHazSimpProposal_2020.pdf

Comments and feedback on these proposed changes may be directed to the NWS via an online survey form at: 
https://www.surveymonkey.com/r/publichazsimp

Please send questions on this proposed change vy by August 21, 2020, to hazsimp@noaa.gov

Subject: NWS is Soliciting Feedback from Specified Partner Sectors
         on their Use of NWS Tropical Products and Services
         through June 30, 2021.

The NWS Tropical Services Program is accepting comments from specified partner
sectors through June 30, 2021, on their use of NWS tropical products and services.
Tropical products are used by a variety of users including broadcast media, emergency
management/public safety officials, and software/web/app developers. The NWS is now
seeking feedback specifically from these users on how tropical products and services
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
Tropical Services Program at:

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:

2 PM EDT Wednesday, June 3rd, 2020
https://attendee.gotowebinar.com/register/7470303407718075147

12 PM EDT Thursday, July 23rd, 2020
https://attendee.gotowebinar.com/register/2408615867344992013;

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: 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

    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.

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.
