Poster Clusters

Poster clusters should be designed to bring together a community working on a specific topic within the broader conference themes. The aim is to help participants to organize their poster viewing and to provide a forum for discussion about the cluster topic. In addition to dedicated on-site poster sessions, all posters will be available on the hybrid platform poster gallery at least two weeks before the conference. Virtual poster sessions will be organized during these two weeks. The poster cluster names will be listed under the OSC programme sessions in the abstract submission system when it opens in December 2022.

If you or your organization/working group/etc., would like to propose a poster cluster topic, please click here to know more about the poster cluster application and to fill in the survey form, no later than 30 September 2022.

Side Events

The OSC will occupy the entire Kigali Convention Center during the week of 23-27 October 2023. The venue has many rooms of varying sizes that can accommodate workshops, meetings, learning labs, townhalls or other events.There is also the option to propose a video for transmission on hybrid platform during breaks and possibly during the conference itself. If you or your organization would like to host an event at the OSC, please click here to know more about the side event application and to fill in the survey form, no later than 30 September 2022.

• Priority Variables Consultation

The CMIP IPO invites you to take part in this consultation on priority variables for inclusion within a core set of variables forming the baseline for exchange of climate model data, in any intercomparison project, in accordance with FAIR data and Open Science principles. This consultation is relevant to those involved in developing and operating climate models, data infrastructure and those utilising climate model outputs. We anticipate this is of relevance to those providing access to and/or utilising the outputs of climate models within commercial, public and third sectors as well as within academia.

The online form is available at: https://bit.ly/WCRP-CV-Phase2OnlineForm. Consultation closes 18:00 UTC Friday 23 September. Please do circulate within your relevant networks.  

The work developing the core variables is being coordinated and led by Martin Juckes, UKRI-STFC. Its implementation is being supported by the CMIP International Project Office

• Open call for CMIP7 Task Teams

The World Climate Research Programme (WCRP) Earth System Modelling and Observations (ESMO) project, through its Working Group on Coupled Models’ (WGCM) CMIP panel and WGCM infrastructure panel (WIP), is establishing a number of Task Teams to support the design, scope, and definition of the next phase of CMIP and evolution of CMIP infrastructure and future operationalisation.

This open call is an invitation to enthusiastic and motivated individuals from across the community, and beyond, to join the CMIP7 Task Teams and contribute to the future direction of CMIP. The first set of Task Team call texts and the application form are now available at the WCRP CMIP website here with an application deadline of 19^thSeptember 2022. Further task teams are being developed and their calls for application will be opened soon.

Please do share across your networks and if you have any questions contact .

Submit your proposals for poster cluster topics and/or side events at the WCRP Open Science Conference (OSC) that will take place in Kigali, Rwanda 23-27 October 2023.  A 2-page flyer that provides a brief overview of the Conference can be found here.

Please submit your proposals no later than 30 September 2022. 

There’s only one week left for abstract submission to the “Workshop on Modelling the Climate System at Ultra-High-Resolution: Resolving atmospheric storms, ocean sub-mesoscale eddies, rivers, and glaciers” that will take place in Boulder, CO, USA from 3-7 October.

Please visit the workshop website to submit your abstract and register as soon as possible and no later than 31st August. Please recall that all abstracts will be automatically accepted as posters from which 10 or so will be selected for additional oral presentation.

Airborne coherent wind lidar measurements of the momentum flux profile from orographically induced gravity waves. By B. Witschas et al. in Atmosheric Measurement Techniques.

WCRP invites the community to nominate candidates (including self-nomination) to become members of the Regional Information for Society (RIfS) Scientific Steering Group (SSG).

The WCRP Regional Information for Society (RIfS) Core Project focuses on research that underpins provision of actionable information for society’s response to climate variability and change. RIfS is in its establishment phase and presents opportunities for framing and developing the directions and priority foci of research on climate for society.

For more details on the nomination process, read more here. Deadline for nominations is 31 September 2022.
