ACTION DUE 6/24/2026: Fill Out HFR Community Team Structure & Interest Survey

[Brian Zelenke - NOAA Federal]

Dear Coastal High-Frequency Radar (HFR) and Integrated Ocean Observing System (IOOS) Communities,

Bottom line up front (BLUF):  Prior to 6/24/2026, would you please fill out the survey here to assist the U.S. IOOS Office and its Surface Currents Program in forming a HFR Community Team of volunteer technical advisors to provide feedback on scientific and technical challenges in support of maintaining a healthy, functional U.S. IOOS HFR National Network and advancing the evidence-based use cases for its products?

To elaborate...

As I spoke about at the recent 2026 IOOS Spring Meeting in Washington, DC and 14th Radiowave Operators Working Group Meeting (ROWG-14) in Newport, Oregon (and online, as it was a hybrid meeting), the IOOS Surface Currents Program is forming a coastal HFR Community Team to serve as volunteer technical advisors, and we would like your feedback to assist this effort.  Similar to the past National HFR Technical Steering Team (see:  "Meeting Summaries" tab here), this new HFR Community Team aims to address the scientific and technical challenges inherent in maintaining a healthy, functional U.S. IOOS HFR National Network, and to provide evidence-based feedback to IOOS leadership and other groups looking into IOOS's observing efforts.  To be clear, this Team is not a Federal Advisory Committee and won't be asked to provide consensus recommendations; instead we hope for broad participation that invites a variety of perspectives from members including representatives from IOOS Regional Associations (RAs), the IOOS Office, and Principal Investigators (PIs) engaged in HFR-related research, development, and operations.

More information about the forthcoming HFR Community Team, its structure, and key areas of responsibility is given in this Google Form along with questions for you to help get this team started off on the right foot.  Sarina Mann, who is with the U.S. IOOS Office, is Cc'd on this e-mail and is working in support of this survey.  If you have any questions about this Google Form, please reach out to sarin...@noaa.gov.  Thank you all in advance for your feedback and continued support of IOOS and its HFR National Network!

Best regards,
Brian

Best regards,
Brian

Dear Coastal High-Frequency Radar (HFR) and Integrated Ocean Observing System (IOOS) Communities,

Thank you for all for the input you provided to the subject survey.  That survey is now closed and Sarina and I in the IOOS Office will be reviewing the feedback received so that we may get back to you accordingly in the days following the July 4th U.S. Independence Day holiday with more information and the schedule for our HFR Community Team's inaugural meeting.   Tentatively we're thinking of holding that kick-off meeting (remotely, via Google Meet) sometime during the last week of July 2026, so if you know of any major conflicting events during that time, please feel free to send a heads-up to Sarina at sarin...@noaa.gov.

Best regards,
Brian

Dear Coastal High-Frequency Radar (HFR) and Integrated Ocean Observing System (IOOS) Communities,

Regarding the e-mail below, I jumped the gun by closing the subject survey early, prior to the "C.O.B. Wednesday" due date I'd written earlier.  So, just to make sure this doesn't short change anyone who was relying on that C.O.B. deadline, the survey here has been reopened and will continue accepting responses until 5:00 PM EDT tomorrow (6/25/2026).  Hope this extra time helps!

Best regards,
Brian

Dear Coastal High-Frequency Radar (HFR) Communities of Practice and Interest,

Please join us for our inaugural meeting of the HFR Community Team.  (Also, thank you again to everyone who filled out the HFR Community Team Structure & Interest Survey we sent back on June 3, 2026 to help us prepare for this team's formation!)

You will find attached to this e-mail:

• For you to read carefully in advance of this meeting to help with your decision to participate, a PDF of this Team's charter—a collaborative, living document created to establish our shared purpose and mission, define this team's scope and boundaries, and set guiding principles and operational expectations for how we will work together (subject to change; the latest version of the Charter is available as a Google Doc here).
• A PDF of this meeting's agenda (also subject to change; the living version of this agenda is available as a Google Doc here).
• A "*.ics" universal calendar file, containing the subject event's details like title, date, time, connection information, and description.  You can import this event file into your calendar platform of choice like Google Calendar, Apple Calendar, or Microsoft Outlook.  Also, please feel free to share this e-mail and calendar invite file with others who may be interested.
• At the time of the meeting, you can join using the video call link here, which is also in that calendar invite.

As a reminder, this team aims to address the operational, scientific, and technical challenges inherent in maintaining a healthy, resilient, and high-functioning national HFR network that is responsive to the needs of its stakeholders.  Invited to join this Team include those who are:

• users and creators of HFR data products;
• representatives from IOOS Regional Associations (RAs);
• staff in the IOOS Office and other collaborating offices of the National Oceanic & Atmospheric Administration (NOAA);
• and Principal Investigators (PIs), sensor manufacturers, data managers, technicians, and stakeholders engaged in HFR-related research, development, and operations.

Broad voluntary participation is intended, including by both domestic and international collaborators, and Team meetings will be conducted virtually via Google Meet.

Note:  A separate Steering Committee will later be formed to help run meetings and develop agendas.

To ensure equity and accessibility across time zones, we plan to vary future meeting times and rotate the day of the week to better accommodate schedules.

----
Thank you—we look forward to connecting,

Dear Coastal High-Frequency Radar (HFR) Communities of Practice and Interest,

I addition to a friendly reminder that the subject meeting will be held tomorrow—as described by the attachments and e-mail thread forwarded below—the following are a few further items of interest:

• ROWG-14 Workshop Report available here.  A report on the proceedings of the 14th Radiowave Operators Working Group Workshop (ROWG-14) that was held May 5–7, 2026 in Newport, Oregon, U.S.A. is available here, and by clicking on the "Meeting Summaries" tab at the website here.
• HFRNet data product generation code available on GitHub here.  With the transition of the NOAA IOOS Surface Currents Program's HFR data assembly center (DAC) known as "HFRNet" into the internal NOAA NESDIS Common Cloud Framework (NCCF) system complete as of July 2025, the codebase used in the NCCF to create HFRNet's data products has been published on GitHub here.  This is a work-in-progress, with more documentation and guidance on how to provide feedback to come.
• HFRNet website code available on GitHub here.  The website here provides visualizations, documentation, statistics, and diagnostics for HFR stations and the products generated from their data in the NCCF.  The release of that website's code in GitHub here includes all four parts of the web application:  an interactive map client (PHP, JS), a data API (Python), a database (MySQL), and the operational scripts (Python).  Each component comes with its separate README.md file and its own Docker Compose configuration.  A top-level Docker Compose file is also provided to run the client, API, and database together, making it straightforward to launch a complete local instance.
• If you haven't done so already, please review any pages, documentation, or THREDDS server links on your own websites to see if they contain the old HFRNet address (which had cordc.ucsd.edu in its URL) and replace them with links to the new HFRNet website or NOAA-NDCB's HFR THREDDS data server, as appropriate.  Also, note that NOAA's National Data Buoy Center (NDBC) provides the sister website here, which is another way for you to visualize and access these same HFRNet data products.

Looking forward to speaking with you tomorrow!


Best regards,
Brian
