GGMT 2019
The 20th WMO/IAEA Meeting on Carbon Dioxide, Other Greenhouse Gases, and Related Measurement Techniques (GGMT-2019)
GGMT meeting was initiated by Dr. Dave Keeling at La Jolla, California in 1975 and has become the cornerstone meeting for the observation of key greenhouse gases and tracers, their isotopes, assessment of new techniques, standardization, quality assurance and data products. The scope covers challenges in the field of precise measurements of atmospheric greenhouse gases, data utilization and integrated products and observational network design. It provides an excellent platform for all scientists in this field to exchange the latest scientific findings and serves as the scientific backbone of the Global Atmosphere Watch Programme (GAW) which has provided the umbrella to all GGMT meetings. Since 1997 the international Atomic Energy Agency (IAEA) in Vienna joined WMO due to the increased use of carbon isotopes in studying the carbon cycle. The conference website is available here.
