APARC SSG nomination call 2024 is now open

The call for nominations to APARC’s Scientific Steering Group (SSG) is now open. The SSG currently comprises 12-14 researchers from around the world with a wide range of expertise in atmospheric dynamics and chemistry. They guide APARC’s priorities and activities, working together with
the SSG co-chairs and the APARC project office.
Please note that you can either nominate a candidate or nominate yourself. The SSG takes a strategic view of APARC’s role, so we are looking for individuals with a broad view of atmospheric science and climate change as well as expertise in their own field. Scientific expertise, career stage as
well as gender and geographical balance are considered. The initial term of service is for four years
(January 2025 – December 2028), with a possible extension of two years.
You find all relevant information and the online form to submit your nomination at the APARC website.
In case you have any questions, do not hesitate to contact the IPO:

S-RIP2 Kickoff Meeting (Boulder, 20-24 July 2024)

We will have a planning Workshop for S-RIP Phase 2 (S-RIP2, in Boulder, CO, USA immediately following the Quadrennial Ozone Symposium (QOS, 15-19 July 2024).  The workshop will begin with an ECS event on Saturday (20 July) and informal small group meetings on Sunday (21 July).  The formal workshop will be Monday 22 July through the morning of Wednesday 24 July.

We particularly want to foster participation of Early-Career Scientists (ECSs: PhD students, postdoctoral fellows) from all over the world in S-RIP2 and encourage those who are attending the QOS in Boulder, as well as local ECSs, to participate in our workshop.  Some financial support will be available for ECS who need to change tickets and/or extend accommodations in Boulder after the QOS.

We particularly encourage applications for the ECS event and participation in the workshop from the Global South. Workshop registration fees will be waived for ECSs. Participation in the S-RIP ECS event on 20 July will be free of charge, including coffee break, lunch, and a social evening; participation in this event may be limited (~10-15 people). 

Please save the dates! Note: An announcement on options for registration and accommodation will be made soon, when those arrangements are finalised.

Kigali Declaration: Climate science for a sustainable future for all

The Kigali Declaration, one of the biggest outcomes of the World Climate Research Programme (WCRP)’s Open Science Conference 2023, calls for immediate climate action, amplification of the relevance and benefits of climate research to society, and increased accessible and equitable investments towards climate mitigation.  

With 734 signatories, the majority of whom were conference participants, the Declaration is the collective voice of the participants of the Open Science Conference. The aim of the conference was to discuss the present state and the future evolution of climate science, and the actions urgently required to mitigate against and adapt to climate change. The participants acknowledged that human-induced climate change and other human impacts on the environment are among the major reasons behind the polycrises and rising inequalities currently faced by the world.

Second Ozone CCI User Workshop (28-29 May 2024)


The European Space Agency’s Climate Change Initiative (CCI) aims to realise the full potential of the long-term Earth Observation archives collected by ESA and Third Party satellite missions. Since 2010, the Ozone CCI team ( has been developing, maturing, generating and sustaining multiple complementary multi-decadal satellite ozone Climate Data Records (CDRs) tailored for climate monitoring, climate research and climate modelling applications. The CCI portfolio consists of total and tropospheric ozone column data products as well as vertically resolved ozone products by nadir and limb-viewing sensors.


The main objectives of this workshop are (a) to bring together scientists involved in the generation of ozone Climate Data Records, as well as (potential) users of such multi-decadal ozone time series, and the broader ozone and climate communities, (b) to present the state of the art in ozone Climate Data Record production, (c) to discuss results from major Climate Data Record users, e.g., stratospheric ozone assessments for WMO/UNEP, tropospheric ozone assessments for TOAR II, studies focusing on UT/LS, evaluation of climate modelling, data assimilation and reanalysis, (d) to collect and update user requirements for ozone Climate Data Records, and (e) to discuss remaining challenges for the generation of ozone Climate Data Records.


Only registered participants will receive meeting access details prior to the workshop. There will be no fee, but you’ll have to bring your own coffee. You are kindly invited to register for the workshop before Tuesday 14 May 13h UTC at:

Second Announcement: SPARC Hunga-Tonga impacts workshop

This is the first call for Abstracts for the 2nd SPARC open science workshop on the atmospheric impacts from Hunga Tonga, at Ecole Normale Supérieure (ENS), Paris, France from Mon 22nd Apr to Wed 24th Apr 2024.

The workshop’s aim is to encourage collaboration and discussions towards the 2025 SPARC Hunga-Tonga impacts report, and we invite interested scientists from the broader atmosphere, climate and geoscience communities to attend to hear and present latest findings on the eruption’s effects.

The first 2 days of the meeting will be the main open-science workshop, with talks and posters on the latest Hunga-Tonga impacts science, sessions aligned to each chapter of the report,

Abstract submission and registration is now open, via the workshop website at:

Second Announcement: International Workshop on Stratosphere-Troposphere Interactions and Prediction of Monsoon weather EXtremes (STIPMEX)
