Call for Papers: ROMEX Special Issue in Atmospheric Measurement Techniques (AMT)

Dear all,

I’m pleased to announce that the Atmospheric Measurement Techniques (AMT) special issue titled
“The Radio Occultation Modeling EXperiment (ROMEX): observational quality, processing, and numerical weather prediction (NWP) applications”
is now open for submissions.

ROMEX, an IROWG-led initiative, aims to assess the impact of ~35,000 daily radio occultation (RO) profiles—collected from 13 missions during September–November 2022—on numerical weather prediction. This international campaign involves contributions from data providers, processing centers, and forecasting institutions across the global research and operational communities.

The special issue welcomes papers using ROMEX data on topics including, but not limited to:

  • RO data quality and processing

  • Evaluation and validation of RO datasets

  • Impact studies in NWP and other atmospheric applications

Submission is open from 1 May 2025 to 31 December 2026 (extensions possible).
🔗 Submit here: https://editor.copernicus.org/AMT/manuscript_registration
Please ensure the correct special issue title is selected during submission. Editorial assignment follows a first-come, first-served policy.

📄 A full description of the special issue is available at:

The second ROMEX (ROMEX-2) workshop registration open

Dear IROWG/ROMEX community,

You are cordially invited to attend the second IROWG ROMEX (ROMEX-2) Workshop, taking place from February 25–27, 2025, at EUMETSAT Headquarters in Darmstadt, Germany.

Initial results of ROMEX activities were discussed at the First IROWG ROMEX workshop in February 2024 and during the IROWG-10 meeting in September 2024 . The Second ROMEX workshop aims to finalize and consolidate  the findings from various NWP centers and research entities, align the presentation of these results, and prepare recommendations for CGMS agencies. The workshop will focus on presentations and discussions in the following areas:
  • Reports on ROMEX related NWP impact studies and applications
  • Best ways to present ROMEX results to stakeholders and decision-makers
  • Status and plans of relevant RO missions
  • Other relevant developments and research pertaining to ROMEX

The first two days of the meeting will feature presentations and discussions, while the final day will include a plenary session dedicated to consolidating ROMEX findings and finalizing the report and recommendations for CGMS. In-person participation is strongly encouraged, though remote access will be available. A detailed agenda will be provided after registration closes.

Please register at the IROWG ROMEX workshop webpage: here

Registration Deadline: January 20, 2025

Note: A full abstract is not required. Following the approach of the first ROMEX workshop, proposals will be accepted as long as the topics are relevant. Please plan your travel in advance, as the agenda will be finalized in early February.

IROWG would like to express sincere gratitude to EUMETSAT for hosting this meeting and is looking forward to seeing you in Darmstadt.

Dear ROMEX community,

You are cordially invited to attend the IROWG ROMEX Workshop on 17-19 April 2024 at EUMETSAT HQ in Darmstadt, Germany. The ROMEX workshop seeks presentations in the following areas:

  • Status and plans of relevant RO missions
  • ROMEX RO data processing and validation of ROMEX data
  • Reports on ROMEX applications and studies
  • Other relevant developments and research pertaining to ROMEX

Additionally, the workshop will facilitate discussions regarding data processing, experimental design, and NWP impact studies, as well as develop the ROMEX intermediate report (required for the CGMS working group meeting the following week) and draft follow-up plans.

The first two days of the meeting will consist of presentations and discussions, and the last day will include a plenary discussion regarding ROMEX and the finalization of the report. We plan to have full-day meetings for the first two days (Wednesday and Thursday, 17-18 April). The Friday meeting (19 April) will end by noon followed by lunch.

Complimentary lunches will be provided at EUMETSAT for three days. There will be an offsite group dinner on Wednesday, 17 April 2024. Please plan to join us as well.

ROMEX Workshop – April 17-19, 2024-and planning survey

Note: The ROMEX Workshop has been confirmed. Therefore, the following survey has been closed. To register for the ROMEX Workshop, please go to the workshop website:

https://www.eventsforce.net/irowg-romex

=======================

Dear ROMEX working group,

Please mark your calendars for the ROMEX Workshop on April 17-19, 2024, a hybrid meeting hosted at EUMETSAT in Darmstadt, Germany. After our recent ROMEX experimental design meeting, we agreed a formal meeting to discuss results together in a forum would be beneficial. EUMETSAT graciously offered to provide meeting space, coffee, lunches and one welcoming reception. We are currently planning for no or modest registration fees.

We’ve strategically chosen these dates to precede the CGMS WGII meeting (week of April 22), allowing us to present our findings and follow-up plans to the CGMS the following week.

Your participation either way is key, and we’re eager to gauge the level of interest in either in person or virtual participation. All ROMEX members are strongly recommended to participate. Please help us shape the workshop by taking a quick survey. Your input is valuable!

Here is the link to the workshop survey:

https://docs.google.com/forms/d/e/1FAIpQLSd663OdR5K1kH9_pq0DWDiNj5MrXgQ5D_aFFQTTvl1ue9emPw/viewform?usp=pp_url

If you have difficulties accessing this survey, you can just write back to me and let me know whether you plan to attend this workshop, in person or remote, and whether you need an official letter of invitation to the meeting. Collections of contributions and short abstracts will occur later as the ROMEX experiments begin, but the planning for this meeting is best to begin now.

Best regards,

Hui

ROMEX: Data Terms and Conditions, NASA-spire data, and some other updates

Dear ROMEX working group,

I’m sending this email to update you since our last meeting in May. We will not have a June meeting since data is still being processed. However, this email will give you some information you have sought.

The Terms and Conditions for using ROMEX data are finalized and are ready to be signed. If you would like to use ROMEX data, please sign the document. This applies to data providers and processing centers and anybody else if you touch data beyond those from your organization.

The document (Terms and Conditions) is in the ROMEX Google folder (restricted to ROMEX participants only). Or you can use the document (pdf) on the IROWG webpage. We accept signatures by an organization or an individual. If an organization signs the letter, please indicate the POC (point of contact) for this organization. This POC will be responsible for receiving the password for the data FTP later. Also, this person will be contacted if there is a violation of the Terms and Conditions during ROMEX. If no POC is identified explicitly, we’ll contact the person who sent in the signature.

Please send the signed document to:

I’ll put a list of the signed organizations on the IROWG-ROMEX webpage later.
News about data:
A big THANK YOU to NASA and Spire! Now NASA-Spire data is available to us. So we are going to have extra data beyond what we already have. We will have about 35000-40000 profiles daily for the ROMEX testing period. Exact data counts will be available later.
What is going on now:
EUMETSAT is collecting data and processing them as necessary. Now EUMETSAT has received data from UCAR, NOAA, EUMETSAT, CMA, Yunyao, PlanetIQ, and GeoOptics and is working to receive data from Spire and Tianmu currently.
The steering committee just had a meeting (a couple of hours ago) with ROMSAF (Thanks to Kent and Santi) to finalize the data distribution procedure. You need to sign the Terms and Conditions, and, once ready, ROMSAF will give you a password to access some website/server. We are going to have some tests before finalizing the procedure.
The data link will be posted to the IROWG-ROMEX webpage later as well.
Last meeting minutes:
Please look at the last meeting minutes in our shared Google folder.  (Thanks to Rick for making the notes)
Next meeting:
We would like to have a meeting soon (probably in July) about data distribution and experiment design. Stay tuned!
I want to acknowledge everyone working hard to keep ROMEX moving forward. We are getting there!
Hui
