Event: 19th WMO/IAEA Meeting on Carbon Dioxide, Other Greenhouse Gases and Related Measurement Techniques (GGMT-2017) (27-31 August 2017; Dübendorf, Dübendorf, Switzerland)Published by: WMO ; 2018
The meeting reviewed current WMO data quality objectives, reference scales and observation strategies, including calibration, quality control, data management and archiving. Target species were carbon dioxide and other greenhouse gases, stable isotopes, and radiocarbon in greenhouse gas measurements. The workshop discussed in detail the harmonization and quality control of isotope measurements, the extension of the measurement network towards more polluted and urban areas, the use of low-cost sensors, and the collaboration of the scientific greenhouse gas and carbon cycle community with the metrology institutes. Many of the discussions were driven by recent technological developments in instrumentations. Analytical advancements have now made possible continuous high precision measurements of many previously difficult to measure compounds. In addition, we discussed the need to calculate and report uncertainties for all measurements.
The group updated the recommendations on WMO data quality objectives, calibration, and data management, as well as on the development of the GAW Programme in general. These recommendations are summarized in this meeting report.
