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.

We look forward to you joining the meeting, and we are grateful to SPARC for sponsoring the event, to keep registration costs low.

 The Safe Landing Climates Lighthouse Activity is an exploration of the routes to “safe landing” spaces for human and natural systems. It will explore future pathways that avoid dangerous climate change while at the same time contributing to the United Nations Sustainable Development Goals (SDGs). The Lighthouse Activity has five Working Groups, the details of which can be found on the Safe Landing Climates webpage.

In this open call, we are seeking new members for two of the Safe Landing Climates Working Groups. These are:

1. Perturbed Carbon Cycle

The Perturbed Carbon Cycle Working Group has several ongoing activities, focussing on the climate response to CO2 and CH4 emissions, the risk of extreme events and associated rapid change in Greenhouse Gas (GHG) sources and sinks, overshoot scenarios, and the reversibility of the anthropogenic perturbation in the context of negative emissions (Carbon Dioxide Removal (CDR), but potentially also methane removal)

We seek self-nominations from experts in the broad fields related to climate and the global biogeochemical cycles, including but not limited to the disciplines of Earth system science, global biogeochemistry, land and ocean ecosystems, atmospheric chemistry, climate mitigation, and Integrated assessments. All interested individuals from the global community are encouraged to apply, particularly individuals from Africa, South America, Asia, and the Small Island States.

2. Safe Landing Pathways

The Safe Landing Pathways Working Group has activities that explore what climate trajectories and destinations are safe or unsafe, for whom, and why.

We seek applications and self-nominations from experts in the broad fields related to Safe Landing Pathways, including but not limited to the disciplines of economics, human geography, public health, biodiversity, conservation and ecosystem management, Earth system governance, and international policy. All interested individuals from the global community are encouraged to apply, particularly individuals from Africa, South America, Asia, and Small Island States.

We have just another week for abstract submissions to the WCRP Open Science Conference (https://wcrp-osc2023.org): deadline on 14th March! The same deadline also applies to financial support requests and expressions of interest to attend the Early and Mid-Career Researchers Symposium (EMCR) Symposium.

We are building an exciting program, with many topical sessions (https://wcrp-osc2023.org/program/program-sessions) that will bring together the work of the WCRP Core Projects and Lighthouse Activities, while reaching out to different communities in a transdisciplinary event. It also features many contributions from our partners,  in terms of scientific research and organizational co-design.

Highlighting also the poster clusters (https://wcrp-osc2023.org/program/program-poster-clusters), which are designed to bring together a community working on a specific topic within the broader conference themes. Posters will form a very important part of the OSC, particularly for early career researchers. In addition to dedicated on-site poster sessions, all posters will be posted on the hybrid platform poster gallery at least two weeks before the conference. Virtual poster sessions will be organized during these two weeks.

The EMCR Symposium programme is taking shape (https://wcrp-osc2023.org/emcr). It will be an excellent opportunity for EMCRs to network with colleagues from different regions and disciplines. We highlight that EMCRs wanting to attend the Symposium must submit an abstract. Applicants will be notified of their selection in May 2023.

There are lots of promotional material on the OSC website (https://wcrp-osc2023.org/about-conference/resources)! Please make use of those and share the information within your networks.

Meet us in remarkable Rwanda! #WCRPOSC23
