    "abstract": "Input Data for Figure 7.3 from Chapter 7 of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6).\r\n\r\nFigure 7.3 shows anomalies in global mean all-sky top-of-atmosphere (TOA) fluxes from CERES-EBAF Ed4.0 and various CMIP6 climate models in terms of reflected solar, emitted thermal and net TOA fluxes. \r\n\r\n---------------------------------------------------\r\n How to cite this dataset\r\n ---------------------------------------------------\r\n 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:\r\nForster, P., T.

A link to the code to plot the figure archived on Zenodo is provided in the Related Documents section of this catalogue record.\r\n\r\n---------------------------------------------------\r\n List of data provided\r\n ---------------------------------------------------\r\n This dataset contains:\r\n\r\n- Anomalies in global mean all-sky top-of-atmosphere (TOA) fluxes from CERES-EBAF Ed4.0 in terms of reflected solar, emitted thermal and net TOA fluxes. \r\n- Anomalies in various CMIP6 climate models in terms of reflected solar, emitted thermal and net TOA fluxes. \r\n\r\n(a) Global mean solar flux anomaly.\r\n(b) Global mean thermal flux anomaly.\r\n(c) Global mean net flux anomaly.\r\n\r\nAnomalies in global mean all-sky top-of-atmosphere (TOA) fluxes from CERES-EBAF Ed4.0 are depicted as solid black lines.\r\nAnomalies in CMIP6 climate models are depicted as coloured lines.\r\nThe multi-model means are additionally depicted as solid red lines. \r\n\r\nModel fluxes stem from simulations driven with prescribed sea surface temperatures (SSTs) and all known anthropogenic and natural forcings. Shown are anomalies of 12-month running means. All flux anomalies are defined as positive downwards, consistent with the sign convention used throughout this chapter. The correlations between the multi-model means (solid red lines) and the CERES records (solid black lines) for 12-month running means are: 0.85 for the global mean reflected solar; 0.73 for outgoing thermal radiation; and 0.81 for net TOA radiation.
