FaIR v1.6.2 calibrated and constrained parameter set

This .json file provides the 2237 ensemble members that are used to run the FaIR simple climate model in the IPCC's Sixth Assessment Report contributions to Working Group 1 and Working Group 3. Drawn from an initial prior ensemble of 1 million, the following constraints are placed upon the results: representation of observed warming from 1850-2019, within observational uncertainty representation of observed ocean heat content change 1971-2018, within observational uncertainty reproduction of near-present day atmospheric concentrations of CO2 from the carbon cycle airborne fraction of CO2 with a distribution similar to the assessed range of Chapter 5, IPCC Working Group 1 AR6 equilibrium climate sensitivity with a similar distribution to Chapter 7, IPCC Working Group 1, AR6 transient climate response with a similar distribution to Chapter 7, IPCC Working Group 1, AR6 projected future warming that is of a similar distribution to the SSP scenarios of Chapter 4, IPCC Working Group 1, AR6, when run with prescribed concentrations
