title: Chapter 2 of the Working Group I Contribution to the IPCC Sixth Assessment Report - data for Figure 2.6 (v20220119)

description: Data for Figure 2.6 from Chapter 2 of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6). Figure 2.6 shows globally averaged atmospheric mixing ratios of ozone-depleting substances and greenhouse gases. --------------------------------------------------- How to cite this dataset --------------------------------------------------- When citing this dataset, please include both the data citation below (under 'Citable as') and the following citation for the report component from which the figure originates: Gulev, S.K., P.W.
