22nd WMO/IAEA Meeting on Carbon Dioxide, Other Greenhouse Gases, and Related Tracers Measurement Techniques (GGMT-2024)
The 22nd WMO/IAEA Meeting on Carbon Dioxide, Other Greenhouse Gases and Related Tracers Measurement Techniques (GGMT-2024) took place back-to-back with the 11th International Carbon Dioxide Conference on 5-8 August 2024 at the INPE campus in Sao José dos Campos, Brazil.
NEW Measurement guidelines for Stable Carbon Isotope Ratio of CH4 has been just published by the IAEA.
The topics covered at the meeting include:
- Quality assurance of greenhouse gas measurements
- Quality assurance of the measurements of the stable isotopes
- Measurements and quality assurance for 14C, O2/N2 and related tracers
- Data products and utilization of the observations
- Advances in the traditional greenhouse gas measurement techniques
- Emerging Observation Techniques including low-cost sensors, Remote Sensing and Integration of Observations
- Observations from the mobile platforms (aircraft, drone, balloon, etc) and over/in the ocean
- GHG flux and ocean pCO2 observations
- Urban Networks and Observations
Recommendations of GGMT-2022 are available in the WMO library. The meeting reviewed these recommendations. The draft will be made available here soon for the discussion.
