Input Data for Figure 7.4 from Chapter 7 of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6).

Figure 7.4 shows radiative adjustments at top of atmosphere for seven different climate drivers as a proportion of forcing.

Figure subpanels

The figure has 1 panel, with input data provided. A link to the code to plot the figure archived on Zenodo is provided in the Related Documents section of this catalogue record.

List of data provided
---------------------------------------------------
This dataset contains:

- Radiative adjustment for tropospheric temperature (orange)
- Radiative adjustment for stratospheric temperature (yellow)
- Radiative adjustment for water vapour (blue)
- Radiative adjustment for surface albedo (green)
- Radiative adjustment for clouds (grey)
- Total adjustment (black)

For the greenhouse gases (carbon dioxide, methane, nitrous oxide and CFC-12) the adjustments are expressed as a percentage of stratospheric-temperature-adjusted radiative forcing (SARF), whereas for aerosol, solar and volcanic forcing they are expressed as a percentage of instantaneous radiative forcing (IRF). Land surface temperature response (outline red bar) is shown, but included in the definition of forcing. Data from Smith et al. (2018b) for carbon dioxide and methane; Smith et al. (2018b) and Gray et al. (2009) for solar; Hodnebrog et al. (2020b) for nitrous oxide and CFC-12; Smith et al. (2020b) for aerosol, and Marshall et al. (2020) for volcanic.
IRFs come from offline calculations by Chris and Gunnar (for CAM4)

tas_SW, ta_trop_SW, ta_strat_SW. alb_LW are always set to zero. Variables are included in netcdf anyways for consistency.
When LW or SW IRFs is not available, The value is set to NaN in the netcdf.
When the IRFs are NaN, the corresponding cloud adjustments are also set to NaN.

Further details on data sources and processing are available in the chapter data table (Table 7.SM.14).

Data provided in relation to figure
---------------------------------------------------
The CSV file used to plot Figure 7.4 is provided:

- 'fig7.4.csv'

The github repository contains all input files to the plotting script for the figure except 'rcmip-concentrations-annual-means-v5-1-0.csv'. These are processed and combined in the code to create a single file 'fig7.4.csv' which is provided. The figure can be reproduced using just this file by running the notebook from box 22 by reading in the csv as variable 'adjustments_df'.

Notes on reproducing the figure from the provided data
---------------------------------------------------
Data and figures are produced by the Jupyter Notebooks that live inside the notebooks directory of the Chapter 7 GitHub repository linked in the Related Documents section. The github repository contains all input files to the notebook except 'rcmip-concentrations-annual-means-v5-1-0.csv'. These are processed and combined in the code to create a single file 'fig7.4.csv' which is provided. The figure can be reproduced using just this file by running the notebook from box 22 by reading in the csv as variable 'adjustments_df'.
