WMO International Greenhouse Gas Monitoring Symposium

Geneva, WMO HQ

WMO is developing a concept for a sustained, internationally coordinated routine Greenhouse Gas Monitoring Infrastructure in consultation with a broad group of stakeholders from both scientific, operational, and policy-setting entities. This 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.

The aim of the infrastructure is to (i) to facilitate and encourage the implementation of a fit-for-purpose GHG surface- and space-based observing systems based on shared best practices, standards, and timely and improved access to all GHG-related observations, (ii) improve international coordination of related modeling and data assimilation activities, and (iii) make progress toward establishment of a practice of utilization of routine products provided by GHG system for post-processing and service provision in a manner that is timely to inform policy decisions. The data generated by such a system would support delivery of robust, quantitative information to nations and communities everywhere, including the Parties of the Paris Agreement, through the tailoring to address mitigation action.


To submit an abstract please use the form below 

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. 

Among the topics planned to be discussed are:

  • Greenhouse gas budgets, impacting processes and associated uncertainties;
  • Observations of GHG in different domains of the Earth System to support GHG analysis (surface-, subsurface-, and space-based);
  • GHG exchange between different domains of the Earth System, processes description and climate feedbacks,
  • Treatment of GHGs in Earth system modeling, required model improvement and quality control procedures,
  • Routine, global GHG monitoring systems: input data requirements and intended output,
  • Post-processing of global systems output and tools for decision-makers’ tailoring,
  • Potential contribution of the globally coordinated GHG Monitoring Infrastructure to UNFCCC processes;

A Symposium Program Committee is co-chaired by Michel Jean (SG-GHG Chair) and Greg Carmichael (SG-GHG Co-Chair).
