IPCC AR6 WGI assessed GSAT Projections

These data sets contain the assessed Global Surface Air Temperature (GSAT) projections and all input data and instructions necessary to reproduce the assessed GSAT projections in the Intergovernmental Panel on Climate Change Sixth Assessment Report (Figure 4.11, IPCC AR6 WGI). The constrained CMIP6 projections are based on the methods from three publications calculating the global mean near surface air temperature relative to the average over the period 1995–2014. They are described in box 4.1. The Effective Radiative Forcing (ERF) time series are reproduced from IPCC WGI chapter 7 and included to facilitate reproduction of the analysis. They are uncoupled to any GSAT change. ERF quantifies the energy gained or lost by the earth system following an imposed perturbation (for instance in green house gases, aerosols or solar irradiance). As such it is a fundamental driver of changes in the earth’s TOA energy budget. ERF is determined by the change in the net downward radiative flux at the top of atmosphere (box 7.1) after the system has adjusted to the perturbation but excluding the radiative response to changes in surface temperature (Figure 7.3, IPCC AR6 WGI). For a detailed description of the ERF time series, please refer to chapter 7 (https://github.com/IPCC-WG1/Chapter-7).
