Global Atmosphere Watch Programme (GAW)

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.

GGMT-2024 participants

 

NEW Measurement guidelines for Stable Carbon Isotope Ratio of CH4 has been just published by the IAEA.

The topics covered at the meeting include:

  1. Quality assurance of greenhouse gas measurements
  2. Quality assurance of the measurements of the stable isotopes
  3. Measurements and quality assurance for 14C, O2/N2 and related tracers
  4. Data products and utilization of the observations
  5. Advances in the traditional greenhouse gas measurement techniques
  6. Emerging Observation Techniques including low-cost sensors, Remote Sensing and Integration of Observations
  7. Observations from the mobile platforms (aircraft, drone, balloon, etc) and over/in the ocean
  8. GHG flux and ocean pCO2 observations
  9. 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.
