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)

on behalf of

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.

Tony Mannucci
IROWG Rapporteur

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 …

IROWG
