List of data provided
---------------------------------------------------
This dataset contains netcdf files of 3-dimensional (time,lat,lon) aerosol optical depth (od550aer) time-series from 1850 to 2014 from the historical simulations performed by 16 CMIP6 models. Multiple ensemble members are included for some models.

Notes on reproducing the figure from the provided data
---------------------------------------------------
This data file should be used in conjunction with the code Fig6.8_trend_plot_AOD_rolling_10change_volcanic_mask.py
This code creates the AOD timeseries (1850-2014) using the ensemble mean of individual CMIP6 models output in AOD_trend.png and is linked in the Related Documents section of this catalogue record.

Process overview
| Title | Caption for Figure 6.8 from Chapter 6 of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6) |
| Abstract | Time evolution of changes in global mean aerosol optical depth (AOD) at 550 nm. The year of reference is 1850. Data shown from individual Coupled Model Intercomparison Project Phase 6 (CMIP6) historical simulations. Each time series corresponds to the ensemble mean of realizations done by each model. Simulation results from years including major volcanic eruptions (e.g., Novarupta, 1912; Pinatubo, 1991), are excluded from the analysis for models encompassing the contribution of stratospheric volcanic aerosols to total AOD. Further details on data sources and processing are available in the chapter data table (Table 6.SM.1). |
