7th SPARC General Assembly

SPARC is holding its 7th General Assembly from 24th to 28th October 2022. The format of the SPARC GA will be different from GA run in the past, as it will be on a multi-hub basis with three locations (hubs) confirmed at the National Center for Atmospheric Research (NCAR), in Boulder, USA, the European Centre for Medium-Range Weather Forecasts (ECMWF), in Reading, UK, and the First Institute of Oceanography (FIO) in Qingdao, China.

This is an exciting new trial of the multi-hub format, designed to retain the face-to-face element and international collaboration while also reducing the carbon footprint of the meeting. While all meting hubs are open to all participants, we strongly encourage participants to attend the hub that minimizes the carbon cost of their attendance.

The conference will combine three, linked face-to-face meetings. There will also be the opportunity for participants to attend remotely. We expect between 350 and 400 participants shared between the three hubs, with two hubs taking part in live oral and posters sessions at any one time.

General overview

SPARC (Stratosphere- troposphere Processes And their Role in Climate), a core project of the World Climate Research Programme, coordinates international research related to atmospheric variability and prediction.

Physical hub and attendance

  • Overall there will be three locations (USA, UK and China) where the conference will be held. We expect around 100 people attending the conference in person at each hub. Two hubs will be ‘online’ at any one time with oral and poster presentations and both hubs will be ‘connected’ via Zoom. Attendees at any of the hubs will be able to give oral and poster presentations.

Virtual audience

  • Virtual participation will be enabled via Zoom or a live stream option with the possibility to ask questions and leave comments.

Recordings of oral and poster presentations will be made available online.
