IROWG email list transition is complete

Dear All,

We have completed the transition of the IROWG email list. The previous address, irowglist@irowg.org, is now officially retired. Going forward, all IROWG announcements will be sent to the new email address. The IROWG website has also been updated with the latest contact information. Please help spread the word within your networks.

I would like to extend my gratitude to Christian Marquardt and EUMETSAT for their dedicated efforts during this transition and their ongoing support for the new email service. I also appreciate your prompt responses and continued support for the IROWG community.

Wishing everyone wonderful holidays ahead and a fantastic 2025!

Potential removal of 1D-Var products from BUFR

Hi all,

In looking further at the new BUFR sequence, we have been asked the question whether the 1D-Var products (temperature, pressure and specific humidity) and the surface quantities (surface pressure, geopotential height of surface) are required. These are referred to as Level2b and Level2c products in the ROM SAF BUFR description:

https://rom-saf.eumetsat.int/romsaf_bufr.pdf

We are thinking that NWP centres don’t use these products, and therefore they can be removed from the BUFR format (they may still be available from data providers in other formats).

If you use these products from BUFR files, then please let us know as soon as possible. If we don’t here that they are used, then we will remove them from the new, revised format specification.

Many thanks,

Neill (on behalf of the BUFR format committee)

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.
