We would like to inform you about the WMO International Greenhouse Gas Monitoring Symposium that will take place at WMO Headquarters in Geneva on 30 January-1 February 2023. The deadline for abstract submission is 1 November 2022, 24:00 CET. Based on your submissions, the programme committee will form the sessions considering the topics covered by the Symposium. The programme will be published on 12 December 2022, and the authors will be informed directly.  Abstract can be submitted at the Symposium web page WMO International Greenhouse Gas Monitoring Symposium | World Meteorological Organization. 

The Symposium is targeted primarily at entities involved in greenhouse gas observations, modeling, data assimilation and related research in all domains of the Earth System. It is open to other interested parties as well. It will also represent an opportunity to seek input and to explore the interest in collaborating on the development of a concept for a sustained, internationally coordinated routine greenhouse gas monitoring infrastructure with a broad group of stakeholders from both scientific, operational, and policy-setting entities. This concept builds on WMO’s experience with the Global Atmosphere Watch and the Integrated Global Greenhouse Gas Information System, and it incorporates some of the operational practices and globally coordinated and agreed methods used in its World Weather Watch.
