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 .

WCRP is delighted to open a call for proposals to host a dedicated project office in support to one of WCRP’s core projects: the Stratosphere-troposphere Processes And their Role in Climate (SPARC).

SPARC is the focal point for climate science related to the atmosphere within WCRP. Atmospheric and climate sciences are increasingly a focus of decision-making across policy, research, and industry, and of wide interest to the general public. In its 30-year (1992-2022) history, SPARC’s activities have generated a wealth of cutting-edge research and valuable datasets. SPARC has a major role in key international scientific assessment reports, including the WMO/UNEP Ozone Assessment Reports which are requested by the Parties of the Montreal Protocol and its Amendments. SPARC is moving forward with an ambitious new strategic plan from 2023, which will further advance those achievements by taking a leadership role at the forefront of international atmospheric science research. All SPARC efforts are part of WCRP’s activities and embedded in its overarching WCRP Science and Implementation Plan.

Benefits to the Host Institution

The Host Institution will significantly benefit from hosting the SPARC IPO by having a close interaction with this critical domain of research. It will serve as a great opportunity for the host to help deliver the exciting new goals of SPARC to the international community. In addition, the host institution will have the benefit of:

• enhancing their international profile through clear identification with the WCRP international community,
• underscoring the commitment of the national research community for international cooperation,
• association and participation with a range of international meetings, workshops, and regional activities,
• collaboration with other networks including those of early career scientists,
• contributing to the well-established links that the engagement of scientists from the host institute has already established through international research projects to the global community of climate researchers.
• career development for early career scientists in connecting them with the international research community and involvement in SPARC activities and outreach panel, 
• playing an important role in refining and implementing WCRP’s new strategy. 

Further, development of an active scientific partnership between SPARC and scientists at the Host Institution is encouraged, with the aim of increased international exposure and additional scientific publications.

The SPARC IPO’s role will be to support this work on all related levels in close cooperation with the SPARC co-chairs and Scientific Steering Group, the WCRP leadership and the WCRP Secretariat in Geneva.

Biomass Burning Uncertainty: ReactioNs, Emissions and Dynamics

Overarching Objective: BBURNED aims to better quantify the current understanding of the uncertainty and variability in biomass burning emission estimation, and determine how to more accurately represent atmospheric chemistry resulting from fire. We will be a conduit to coordinate and organize the international scientific community to improve understanding of the current and future impacts of wildfires, prescribed burning and agricultural fire on public health and climate by addressing the uncertainties in atmospheric chemistry processes influenced by biomass burning.

We are pleased to announce a “Hunga-Tonga impacts” open science workshop aligned to the new SPARC HTHH cross-activity focus project, the online event on Tue 16th & Wed 17th 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.

The 15th January 2022 HTHH eruption was the most explosive in the satellite era, and represents a new regime of volcano-climate forcing, where emitted water vapor and emitted SO2 are each causing substantial radiative forcings and impacts on the stratospheric ozone layer.

We invite Abstracts on the full breadth of science around the Hunga-Tonga volcanic cloud and its impacts, with the Abstract deadline 2 weeks tomorrow (Friday 21st April).

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

Please register for the event at the workshop website.

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.
