Local organising team: Sergey Khaykin, Bernard Legras, Pasquale Sellitto, Clair Duchamp & Aurelien Podglajen

Workshop outline:

The January 2022 Hunga Tonga–Hunga Haʻapai (HTHH) eruption was the most explosive volcanic eruption in the satellite era, and the water-rich plume is causing substantial impacts on the stratosphere and climate.

A SPARC cross-activity HTHH impacts project has convened a special Hunga-Tonga impacts report for publication in late-2025. The report will feed into the 2026 UNEP/WMO Scientific Assessment of Ozone Depletion, providing a benchmark synthesis of the eruption’s impacts on the stratosphere and climate. 

This 2^nd open science workshop invites latest research on Hunga-Tonga’s impacts on the atmosphere, with modelling and observational studies of the eruption itself, the progressing volcanic aerosol and water vapour and impacts on climate and the stratospheric ozone layer.

This conference will take place in cooperation with the DFG SFB TP-Change and SPARC

The upper troposphere/lower stratosphere (UTLS) region is important for global climate. Transient processes and small scale scale dynamics at the tropopause affect the distribution and gradients of radiatively active species, aerosols and clouds which in turn may feed back on dynamics.

The focus of the meeting will be on UTLS processes and their feedbacks involving experimental research as well as theory and modeling. We aim at bringing together the expertise on tropopause relevant topics from different fields of research to discuss their relevance for the global atmosphere.

Invited Speakers already confirmed:
A. Gettelman, UCAR, B. Randel, NCAR, C. Williamson, NOAA, A. Hertzog, IPSL

Research Contributions will be organised into the three TPChange research areas:

• Research Area A – the role of aerosol and ice particles in the UTLS, their formation, chemistry, evolution and effect on the atmospheric radiation budget
• Research Area B – the interaction of dynamical and microphysical processes in the UTLS
• Research Area C – large scale processes and the impact of processes of all scales on UTLS composition and variability, their expected changes in the future and their impact on present and future climate

Time frame will be
*Monday 10:30 to Thursday 13:00 (external guests)
*Thursday after lunch internal discissions will take place, and on Friday training sessions are scheduled.

The National Institute of Aerospace, working with NASA Langley Research Center, in the United-States,  is opening a Postdoctoral position in Earth Science to study the impacts of volcanic eruptions, fires and pollution on stratospheric composition and climate.

WCRP SPARC is sponsoring a 3-day training school on “Climate Data Science & Artificial Intelligence in the Global South” from October 29 to 31 at the University of Rwanda – College of Science and Technology. The training school is scheduled to follow the WCRP Open Science Conference in Kigali from October 22 to 28, which will attract climate researchers from around the world.

The training school is organized by Dr Mohamadou A. Diallo, Prof. Amadou T. Gaye, Prof. Michaela I. Hegglin and Prof. Ted Shepherd as part of the SPARC Outreach Panel in collaboration with the University of Rwanda. We are targeting Early-Career Scientists (i.e. BSc, MSc and PhD students, as well
as postdoctoral fellows) from all over the world who are attending the WCRP OSC in Kigali, as well as local students and researchers. Participation may be limited (30 places), and ECS applications from the Global South are particularly encouraged.

Participation in the training school is free of charge. Coffee breaks, lunches and accommodation are also included, as well as a social evening. Financial assistance is available for those who need to cover the cost of flight changes for at least a limited number of ECSs.

The deadline for applications is October 15, 2023. For applications, please send an email to Mohamadou A. Diallo (m.diallo@fz-juelich.de) at Forschungszentrum Jülich, Germany and include information on your background, university, country of origin as well as how you think this training school will help you in your current or future projects.

Or contact the organizers: Mohamadou Diallo from Forschungszentrum Jülich.

The registration deadline to attend the event in Munich, Germany is extended to August 31.

Please make sure to register by then via the link:

The Argentinean Hub of My Climate Risk (WCRP) invites you to the following webinar and kindly asks you to circulate this information within your networks:

Fuentes de información climática. ¿cómo influyen nuestros valores y contexto?

Sources of climate information: The role of our values and context

23 August 2023, 14:00-15:30 UTC

This webinar will address the sources of information and lines of evidence used for the construction of climate knowledge. Is the physical science of climate an “objective” science or is it influenced by the

context and values ​​of the researcher? Also, are the sources of information that we choose important for the societal relevance of climate knowledge?

The webinar is the third in a series on “Actionable Climate Knowledge,” organized by the Argentinean Hub of the WCRP My Climate Risk Lighthouse Activity. The webinar will have simultaneous interpretation in Spanish/English.

The recordings of the first two webinars from the series are now available: https://sites.google.com/view/mcrhubconicet/eventos/ciclo-de-webinars

Both webinars can be viewed in Spanish or English.

Enjoy reading through an interesting collection of workshop reports and SPARC science descriptions.

Thank you to everyone who has submitted abstracts for the CCMI workshop. We are beginning work to organize the program based on the contributions we have, but given that it is summer time for many of you and there have been a few recent enquiries about submitting abstracts, we have left the abstract submission system open for a few more days. The system is now due to stop accepting new submissions at the end of the day August 4^th. So if you have been thinking about submitting an abstract, there is still time!

  As a reminder, the workshop website is at http://www.meteo.fr/cic/meetings/2023/ccmi/

Registration to the workshop (9-13 October, Munich) is now available trough: https://www.wavestoweather.de/meetings/sparc-snap-2023/index.html

Note that all ECS and everyone receiving travel support (s recently announced in a separate email) is eligible for the reduced registration fee of 150 Euros.

Registration Deadline is August 18.

Please join us at the upcoming AGU Fall Meeting 2023 for our “Climate forcing: quantifying the roles and responses of anthropogenic and natural climate drivers” session (GC027).
 
The conference will run in-person and virtually this year from Monday to Friday, 11-15 December 2023 in San Francisco, CA, USA, 8:30am-7:30pm Pacific Standard Time.

Session Description:

This session highlights research quantifying and assessing uncertainties in forcing agent evolution and their climate influence using Earth System Model simulations, or Earth observations. We invite contributions on all aspects of climate forcing research, including the development of historical and future forcing time-series, analyses that use idealized, single-, multi-model approaches or emulators, or observational methods to evaluate climate responses. We are especially interested in studies that examine the responses to forcing changes through time, using the current (CMIP6) or previous CMIP phases. Research that considers multiple components of the climate system (the ocean, atmosphere, cryosphere, land surface/subsurface, and biology) and provides evidence for linkages and coherent forced responses is highly encouraged.

Abstract submission deadline: Wednesday 2nd August 2023, 23:59 EDT/US Instructions and abstract submissions: https://www.agu.org/Fall-Meeting or https://agu.confex.com/agu/fm23/prelim.cgi/Home/0
