17th WMO/IAEA Meeting on Carbon Dioxide, Other Greenhouse Gases, and Related Measurement Techniques (Beijing, China, 10-14 June 2013)




The “17th WMO/IAEA Meeting on Carbon Dioxide, Other Greenhouse Gases, and Related Measurement Techniques (GGMT-2013)” was held on 10-14 June 2013 in Beijing (China). This edition of the meeting was organized by the World Meteorological Organization (WMO) through its Global Atmosphere Watch Programme (GAW), the International Atomic Energy Agency (IAEA), the China Meteorological Administration (CMA), and the Chinese Academy of Meteorological Science (CAMS). This meeting is held every two years. Its first edition was held in 1975 in La Jolla (California). Experts on precise and accurate atmospheric greenhouse gases measurements coming from all around the world attend this meeting. In each edition of this meeting, many technical aspects are discussed and a document with recommendations is drawn up.

The meeting focused mainly on the following greenhouse gases: carbon dioxide (and its isotopes), methane, nitrous oxide, and sulphur hexafluoride; and also on other related tracers: carbon monoxide, hydrogen, and the O2/N2 ratio. The topics considered concerning these gases include: measurement scales, standards, comparisons between laboratories and between measurement techniques, integration of the observations, data policy, measurement and calibration techniques of greenhouse gases and their isotopes, developments in the measurement networks and novelties concerning the stations. In the website of the meeting (click here to access it), the oral and poster presentations of the meeting are available.

At the Izaña Global GAW station the following greenhouse gases (and related gases) are measured using in situ techniques: CO2, CH4, N2O, SF6, and CO. The greenhouse gases and carbon cycle program leader of Izaña Atmospheric Research Center attended this meeting. He gave a talk entitled “Izaña global GAW station greenhouse-gas measurement programme. Novelties and developments during October 2011 – May 2013” (click here to get the slides in pdf).
