Based on data

Advanced Global Atmospheric Gases Experiment (AGAGE Measurements) Currently there are 33 compounds available for public access: ALE/GAGE/AGAGE data . Monthly means and standard deviations of data. Measured under background (un-polluted) conditions.

Greenhouse Gases (NOAA) Earth System Research Laboratory - Global Monitoring Division

Used in indicators

Are atmospheric greenhouse gas concentrations changing to levels compatible with the 2 °C (and possibly 1.5 °C) Paris Agreement temperature targets?
