WMO Greenhouse Gas Bulletin (GHG Bulletin) - No.15: The State of Greenhouse Gases in the Atmosphere Based on Global Observations through 2018
Measurements of the content of radiocarbon (14C) in atmospheric carbon dioxide (CO2) provide a unique way to discriminate between fossil fuel combustion and natural sources of CO2. Simultaneous observations of CO2 and 14C demonstrate the decline of 14C content in atmospheric CO2 caused by CO2 addition from fossil fuel combustion. This finding illustrates the importance of long-term measurements of atmospheric composition by laboratories involved in the WMO Global Atmosphere Watch (GAW) Programme in helping identify greenhouse gas emission sources.

It manages four observatories in Tenerife, including the high altitude Izaña Observatory, which was inaugurated in 1916 and has since carried out uninterrupted meteorological and climatological observations and become a WMO Centennial Station.
This report summarizes the many activities of the Izaña Atmospheric Research Center.
Boletín sobre los gases de efecto invernadero - N°15: Estado de los gases de efecto invernadero en la atmósfera según las observaciones mundiales realizadas en 2018
Las mediciones del contenido de radiocarbono (14C) en el dióxido de carbono atmosférico (CO2) ofrecen una manera singular de distinguir entre la quema de combustibles fósiles y las fuentes naturales de CO2 . Las observaciones simultáneas de CO2 y 14C demuestran la disminución del contenido de 14C en el CO2 atmosférico provocada por la incorporación de CO2 procedente de la quema de combustibles fósiles.
