The concept note articulates in detail the existing components of G3W that form the foundation for the implementation (Figure 2). Two technical workshops were conducted to further evaluate the status of current capabilities and their readiness level, and to define the most critical gaps that need to be addressed to advance G3W implementation. The observational workshop was attended by about 130 experts on site with additional 70 participating virtually, while the modelling workshop was organized “by invitation” and included 30 experts in person and 20 experts online.  

Key outcomes and recommendations are formulated in the reports of the respective meeting, and they are available in the WMO library.

The SG-GHG is a joint study group composed by 35 world renown multi-disciplinary experts invited by WMO in August 2022 after the EC-75 to develop the G3W-IP. G3W-SG Sub-groups have led the development of different building blocks that compose this document.  

The G3W building blocks are articulated in the following 6 sections. It is well recognized that capacity building including training are relevant for all the activities listed in the technical sections of the document. Moreover, while G3W is focused on the operational deployment, it is acknowledged that the research and service components are quality requirements for the continuous operations and a necessity for all the building blocks.
