We apologize for the premature message sent earlier today. It is with great sadness that we report the passing of Josep Aparicio while he was attending IROWG. The community is in shock and coping as best we can. We held a memorial this morning to honor him and his memory. We hope you join us in keeping his family in your thoughts. Josep will be greatly missed. An electronic card that will be sent to Josep’s family has been arranged. We welcome your contribution if that is your interest. https://www.groupgreeting.com/sign/b8442ecfc508b74<https://urldefense.us/v3/__https://www.groupgreeting.com/sign/b8442ecfc508b…> We are so sorry for this news. Do not hesitate to reach out. Sincerely, Tony Mannucci, Rapporteur Ulrich Foelsche, Co-chair Hui Shao, Co-chair

Discussion topics for NWP-subgroup
by Neill Bowler 11 Sep '26

11 Sep '26

OFFICIAL Dear IROWG community, We are currently preparing the agenda for upcoming discussions of the IROWG NWP Working Group and would appreciate your input. Are there any issues, challenges, scientific questions, or emerging topics that you would like the group to discuss? This could include operational experiences, data quality concerns, assimilation developments, observation operator issues, future missions, or any other topic relevant to the use of RO observations in NWP. So far, we have this tentative list of topics: * Is there a case to be made for NWP benefiting from more than 20k occultations per day? * What evidence do we have for the additional benefit from an even coverage of data in latitude and local time? (Thanks Rick for sharing Nikki's paper) * With the transition to US data to NOAA-STAR, what does the community need in order to ensure that the transition is successful? Please send us your suggestions by replying to this email. We welcome contributions from all members of the IROWG community. We look forward to hearing your ideas.

02 Sep '26

Dear IROWG, please have a look at the (almost final) *conference program* at https://opacirowg2026.uni-graz.at/en/programme/ or directly at https://static.uni-graz.at/fileadmin/_files/_event_sites/_opacirowg2026/OPA… We have been able to allocate a talk for everyone, who wanted a talk - and a poster, for everyone who wanted a poster (poster boards are 140 cm high and 90 cm wide). I hope that you don't mind if you should find your contribution as an "invited" one. By default, the *hotel registration* is open until *21:00* (9 pm). If you arrive later - please inform the hotel (and also us). In the extremely unlikely case that you have not *registered *yet - or signed on for the *social events* - please do so. There is *no on-site registration*. On *Saturday* afternoon we will make a *small **hiking tou**r* in the surrounding vineyards (picture attached), where we will also learn how the wine is grown (before we taste it at the conference dinner and on Monday). You don't need high-mountain equipment, but some appropriate shoes and rain protection. This site is in German only, but the pictures at the bottom of the page should give you an idea what to expect: https://www.fachschulen.steiermark.at/cms/beitrag/12794339/159651264/ We are looking forward to welcoming you in Austria - next week!
