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:

Rachelle Antal-Wokes <Rachelle.Antal-Wokes@eumetsat.int>
Christian Marquardt <Christian.Marquardt@eumetsat.int>
or any of the ROMEX steering committee member

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!

Dates for IROWG-10 and potential inter-sessional meetings

Dear IROWG,

We are pleased to announce that UCAR/COSMIC and JCSDA will host our next IROWG workshop (IROWG-10). The workshop will be held over the UCAR campus in Boulder, Colorado, US, September 12-18, 2024.

Please note the dates are different from what we discussed from IROWG-9 due to some other related RO events happening at the end of this calendar year. To accommodate the gap between these two IROWG workshops and the upcoming CGMS-52 meetings in Spring 2024, inter-sessional meetings (virtual, around February-March 2024) are being considered at this point. We will iterate this idea with the IROWG subgroup lead. If you have any comments and ideas, please feel free to talk to any subgroup lead or communicate directly with us.

Hui Shao (IROWG co-chair)

Uli Foelsche and Tony Mannucci (IROWG co-chair and Rapporteur)

Hui Shao will be the next IROWG co-chair

Dear IROWG community,

We are very happy to report that Hui Shao (NOAA/Joint Center for Satellite Data Assimilation) will be our next IROWG co-chair.

The official inauguration will take place at the OPAC-IROWG workshop in September.

Thank you to all who participated in the voting process.

And a very big THANK YOU to Sean Healy for his many years of service for the IROWG community!

Sean will still be heavily involved in the preparation of the OPAC-IROWG and CGMS workshops and
then gradually hand over to Hui.

Draft IROWG 7 minutes and summary – please give feedback

The DRAFT of the Full Minutes and Summary of the IROWG-7 Workshop
is available on IROWG-7 .

Thank you very much to all who contributed!

Please provide comments by May 3 latest, since this document (in particular
the first three pages) will be the basis for the IROWG report to CGMS.

We have also uploaded some CGMS documents under irowg.org/documents/
like the Vision for WIGOS in 2040 or a very recent CGMS Risk Assesment Review.
The RO-relevant part is here:
CGMS-48-WGIII risk assessment review – RO part with some important
information highlighted in red.

You will notice that RO is a focus area, and that CGMS sees a
“Continuity risk for the number and geographic distribution of radio occultations; especially in the low- to mid- latitudes” and a
“High risk of not meeting the commitment from low inclination orbits in the later part of the decade as there are no plans for a follow-on to COSMIC-2” with
“Inconsistent coverage from polar and high inclination orbits throughout the period”

“An HLPP (High Level Priority Plan) objective already exists to advance the atmospheric Radio Occultation constellation, with the long-term goal of providing 20000 occultations per day on a sustained basis”

It seems that some of our recommendations have been heard …
