Methodology
Observed trends in greenhouse gas concentration levels. Greenhouse gases differ in the way they affect the climate system. In order to sum the effects of the individual greenhouse gasses and other forcing agents in the atmosphere, the so-called ‘greenhouse gas equivalent concentration’ has been defined. This is the concentration of only CO₂ that would cause the same amount of radiative forcing as a mixture of CO₂ and other forcing agents (greenhouse gases and aerosols)
Data sources
CO2 concentration provided by National Oceanic and Atmospheric Administration (NOAA)CH4, N2O, HFCFCs, CFCs concentration provided by Advanced Global Atmospheric Gases Experiment (AGAGE)
