AGAGE global network
AGAGE measures all important greenhouse gases (GHGs) and ozone depleting substances (ODSs) in the global atmosphere AGAGE measures synthetic greenhouse gases (GHGs) and ozone depleting substances (ODSs) at 13+ sites around the world. Measurement sites are operated by SIO and many international partners. The central AGAGE experimental and calibration laboratory is located at Scripps Institution of Oceanography at the University of California, San Diego.
Climate impact (radiative forcing) from greenhouse gases (GHGs) Combined radiative forcing (RF, impact on the climate) of all GHGs is dominated by carbon dioxide (CO2), followed by methane (CH4), the sum of all ozone depleting substances (ODSs), nitrous oxide (N2O), and the sum of all synthetic GHGs. RF from HFCs is growing fast. Several ODSs are also strong GHGs, foremost the chlorofluorocarbons (CFCs).
CO2 (carbon dioxide), CH4 (methane), ODSs (ozone depleting substances), N2O (nitrous oxide), CFCs (chlorofluorocarbons), HCFCs (hydrochlorofluorocarbons), solvents (chlorinated solvents and feedstock compounds), halons (brominated fire fighting compounds), PFCs (perfluorocarbons), HFCs (hydrofluorocarbons), SF6 (sulfur hexafluoride), SO2F2 (sulfuryl fluoride), NF3 (nitrogen trifluoride). This and the following three plots were produced by CSIRO, one of our many international partners.
