The Quadrennial Ozone Symposium Organizing Committee is pleased to announce the dates and location of QOS 2024. The meeting will be held in-person in Boulder, Colorado, USA from 15-19 July 2024, and hosted by the University of Colorado Boulder with a hybrid virtual option. We are excited to follow in the footsteps of a wonderful QOS 2021 graciously hosted online by Yonsei University, Korea. Please see below/attached the announcement poster and stay tuned for updates from the Organizing Committee on abstract submission, registration, venue, travel, and other information. We look forward to seeing everyone working on everything ozone science in Boulder and online in July 2024!

The next hybrid CORDEX conference will be held 25-29 September 2023 at ICTP, Trieste, Italy, and IITM  in Pune, India as well as online.

Registration is now open on the website.

We invite you to join us for our upcoming discussion on Tipping Points in Education and Digitalisation, taking place on 25 May 2023, 15:30 – 17:00 CEST. 

This webinar is part of the Tipping Points Discussion Series organized by AIMES, the Earth Commission, the WCRP Safe Landing Climates Lighthouse Activity, and partners. The series aims to advance knowledge of tipping elements, irreversibility, and abrupt changes in the Earth system – both in natural and social systems. Our two speakers are: 

• Raya Muttarak (University of Bologna) – Exploring the role of education as a potential accelerator of sustainable society
• Ridhi Kashyap (University of Oxford) – Digital technologies as accelerators of information diffusion

The discussion will be moderated by Anne Goujon (IIASA)

All information and the link to register are available on the FutureEarth website.

Abstract submission is extended for the joint DynVar/SNAP workshop on “The Role of Atmospheric Dynamics for Climate and Extremes”, which takes place in october at the LMU in Munich, Germany.

Please find all relevant information, including the link for abstract submission and information on avaiable travel support on the meeting webpage.

Registrations for the WCRP Open Science Conference in Kigali, Rwanda, are now open! Visit https://wcrp-osc2023.org/registration to register and to find further information.

We have also secured special rates at several hotels in Kigali. In https://wcrp-osc2023.org/accommodation you will find the link to the list of hotels and the booking system prepared by TravelZuri. Looking forward to seeing you all in Kigali!

The WCRP Explaining and Predicting Earth System Change Lighthouse Activity invites you to join the third webinar of the series that will provide a discussion forum on topics focused on predicting and explaining a range of different climate phenomena and events, while supporting the further development of a scientific agenda. 

This fourth webinar will focus on marine heatwaves and aspects related to a changing climate.

SPEAKERS:

• Alex Sen Gupta (University of New South Wales, Australia): Local processes and large scale drivers of marine heatwaves
• Antonietta Capotondi (University of Colorado at Boulder, USA): Large-scale climate drivers of Northeast Pacific marine heatwaves
• Regina Rodrigues (Federal University of Santa Catarina, Brazil): Marine heatwaves in the context of compound extreme events

The event will take place on 15^th May 2023, from 13:00hs to 14:30hs UTC. Speakers will give a 20-minute talk each followed by a round table discussion, with questions from participants. 

Registrations are free and can be done via https://EPESC-webinar-marine-heatwaves.eventbrite.co.uk

The goal of the workshop is to review the progress since the last TriMIP workshop (TriMIP-3) that brought together the active and collaborative communities of AerChemMIP, RAMIP, RFMIP, and PDRMIP. This workshop will focus on advances in our understanding since AR6, identifying gaps and informing future research directions based on the community “Composition Air quality Climate inTeractions Initiative (CACTI): Emissions to Response”.
 
The hybrid workshop will be held in-person at GEOMAR in Kiel from Tuesday 13 June to Thursday 15 June 2023, with an option to join online. The workshop will consist of a mix of presentations and discussions, which we aim to partly record and make available with limited access. We kindly invite you to submit abstracts on your relevant work addressing at least one of the three CACTI goals:

1. Characterize ERFs and assess adjustments from historical and future changes in atmospheric composition and SLCFs emissions in global models
2. Quantify the climate and air quality responses to global and regional changes in SLCF emissions
3. Understand the Earth System feedbacks through chemistry and aerosols in response to anthropogenic climate change

Abstract submission is open until 02 May 2023 and can be done by completing this form. Details on how to register will be announced in due course. Further details, including practical information for arranging travel, can be found on the CACTI webpage.
 
Further announcements will be made through this CACTI mailing list. If you have not signed up yet, we encourage you to subscribe by sending an email to .
 
We look forward to receiving your abstracts and seeing you in June.

This Friday is the Abstract deadline (21^st April) for the online “Hunga-Tonga impacts” open science workshop (Tue 16^th & Wed 17^th May 2023).

SPARC has established a new cross-activity focus project on the impacts from the 2022 Hunga-Tonga Hunga-Ha’apai eruption (HTHH) and will co-ordinate a 2025 “Hunga-Tonga impacts report” aligned to the 2026 UNEP/WMO Scientific Assessment of Ozone Depletion.

We invite Abstracts on the full breadth of science around the Hunga-Tonga volcanic cloud and its impacts, The workshop aims to encourage collaboration and discussions towards the Hunga-Tonga impacts report, and we invite interested scientists from the atmospheric science and geoscience communities to join the meeting to hear latest findings on the eruption’s effects

The online meeting will be 2 half-day sessions (13:00UT to 17:30 UT), with Hunga-Tonga science talks, and the workshop website hosting links for discussion of online poster PDFs.

Abstract submission is via the workshop website (during registration):

https://eu.eventscloud.com/website/11073/home/

We are grateful to SPARC for sponsoring the event, registration is £30 standard and £15 for ECR/students.
