Second announcement and call for abstracts for the joint FISAPS – GW Symposium at Yonsei University, Seoul in June 2025

This call is purely for abstracts, and we will circulate a registration form for the meeting separately in early 2025. Please feel free to forward this message more widely as you see fit; all are welcome, and you do not need to be a formal member of either Activity to attend or present.

 We are happy to consider any abstract within the scientific remit of the GW Activity or FISAPS, whether in the area of modelling, theory, observations or other. You will be asked to specify if your abstract is closer to the area of FISAPS or GWs, but there is an option to say it is relevant to both and there will be joint sessions between the two meetings suitable for such topics. Presenters can request oral, poster or flash (up to two minutes, with slides) formats for their presentation, and it is fine to submit multiple abstracts. We hope to send decisions on accepted abstracts within a few weeks of the closing date.

 You can find a form to submit your abstract here: https://tinyurl.com/gwfiabstracts.  The closing date is Saturday 11^th of January.

An International Symposium Celebrating 35 Years of Global Atmospheric Research Enhanced by NDACC/NDSC Observations

The 2025 NDACC Symposium, hosted by Hampton University, celebrating 35 years of atmospheric research fostered by Network observations, will provide a forum to exchange information on the latest scientific achievements using NDACC and related observations, and to present NDACC’s measurement strategy for the future. We expect 150-200 scientists to participate in person, with more joining online.

Further information about the NDACC Symposium will be distributed through the ndacc.org webpage (starting in January 2025) with the abstract call coming in early spring of 2025.

Improved simulations of the stratosphere for better predictions of
weather, climate and extreme events

A joint QBOi – SNAP – QUOCA (QSQ) workshop
24-28 March 2025, Cambridge, UK

The workshop’s purpose will be to facilitate the sharing and discussion of the latest results on the role of the stratosphere in models relevant for enhancing predictability on all timescales. The workshop will serve as the in-person kick-off for the new QUOCA (QUasi-biennial oscillation and Ozone Chemistry interactions in the Atmosphere) joint QBOi-CCMI project. The aim of the workshop is to better understand stratospheric processes and variability, uncertainties, and their influence on surface climate and predictability. Free-running, initialised, and nudged simulations designed to better understand the stratospheric response to external forcings (such as climate change or geoengineering), or to improve the representation of the predictable signal in surface climate related to stratospheric processes, are also encouraged. Studies examining the potential benefits of the use of artificial intelligence are welcome.
The workshop will consist of a mixture of invited and contributed talks, posters and reports on outcomes of the latest multi-model QBOi and SNAPSI experiments employing common nudging methodologies, as well as the QBOi-ENSO and the QUOCA experiments. Breakout sessions will identify gaps in our current knowledge that can usefully inform further coordinated model experiments, and work towards community consensus on their design. Breakouts will also focus on identifying how results from current QBOi, QUOCA and SNAP research can be best used to inform model development and broader scientific activities such as future CMIP planning. To get the full benefit from active breakout discussions, the workshop will be in-person, though it is hoped limited online options will be offered.

Abstract submission is open until December 2.
