Presentations will be made available online at 22nd WMO/IAEA Meeting on Carbon Dioxide, Other Greenhouse Gases, and Related Tracers Measurement Techniques (GGMT-2024) \| World Meteorological Organization G3W Table for compatibility goals covers GAW application (climatology) and the one for operational applications should be developed independently GGMT will revise Chapter 16/17 of the recommendation of GAW in the context of the network design, attach it to RRR GGMT recommendations on stable isotopes is to be updated (Guidelines were published by IEAE Measurement of the Stable Carbon Isotope Ratio in Atmospheric CH4 Using Laser Spectroscopy for CH4 Source Characterization \| IAEA). COS and Radon measurements discussions to be included. ICDC (International Carbon Dioxide Conference) is proposed to become biannual. Survey/Mapping on who does OSSEs for Network Design is important (G3W Modelling TT) Oksana Tarasova to share the presentations and the paper on OSSEs (Designing surface CO2 monitoring network to constrain the Indian land fluxes - ScienceDirect). Actions: Recommendations on GAW Technical Report recommendations Actions: GAW Research community measurements techniques. Actions: Exhibitions of GHGs measurements providers. Joshua Campbell present as HMEI to connect on RRR and help define fit for purpose sensors Low-cost sensors require a joint effort from Research-grade cost reducing over time Industry-grade precision upgrading over time Picarro, Miro-Bruker, Li-Cor, ABB-Group-Los-Gatos Empa - glatec - MiroBruker There is appetite on Network design
Projects	Oxana Tarasova	BAMBOO potential to demo AERIS sensors: 6 instruments, 2 locations. Half a year of data. Trasported CO2. CO C14 COS CO2 measured on the sites. October meeting relevant for G3W ICOS-Cities : WMO is a partner. There is a planning of the meeting in Barcelona in November for the ICOS-cities stakeholders. 7-10 April 2025 Urban GHG C1 book together with IG3IS. ICOS Cities. Global Urban GHG work. 2025 Action: IPCC urban reports Jocelyne already engaged as national expert with the IPCC
	Bin Qu	G3W deliver in the next 2-4 years will builds on Data-access as the foundation of G3W Operational-vocation as the distinction element of G3W G3W technical expertise is clustered Guidance on insitu data requirements (G3W-Network) Mechanisms of data exchange (G3W-Data) Methods for data integration (G3W-Modelling) G3W R2O transition will need 4-levels of activities Compliance level via WIGOS Manual Governance level via WMO-INFCOM/SERCOM Competence-based training Financial level via WMO-RMS G3W frameworks will need 2-areas Technical Regulatory Framework Strategic Engagement Framework G3W mapping of existing Observations Library & Publications search, find the PIs
	Somyung Yeo	G3W Website ready for deployment Podcast from G3W is proposed to extent beyond the Secretariat with VH/Greg G3W website on WMO G3W task-teams
