title: Chapter 6 of the Working Group I Contribution to the IPCC Sixth Assessment Report - Input data for Figure 6.7 (v20230210)

description: Input Data for Figure 6.7 from Chapter 6 of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6). Figure 6.7 shows distribution of PM2.5 composition mass concentration (in μg m-3) for the major PM2.5 aerosol components. --------------------------------------------------- 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: Szopa, S., V.

PM2.5 stands for particulate matter in the air that are 2.5 micrometers or less in diameter. --------------------------------------------------- Notes on reproducing the figure from the provided data --------------------------------------------------- The data is used as input of the code (violin_regions.py and worldmap_AR6_nocoasts.py). violin_regions.py: Python code that creates the regional violin subplots. The user needs to run the code for each subregion separately by activating the lines 6-17 accordingly. worldmap_AR6_nocoasts.py: Python code that creates the world map in the center of the figure, including the location of the observational sites used. Each of these scripts work independently. The nine individual plots produced by violin_regions.py can be collated with the map created by worldmap_AR6_nocoasts.py to produce the figure 6.7.
