1.5 Experiments: abrupt quadrupling of CO2 plus reduction in total solar irradiance (G1)

Record Label : G1

Record Title : abrupt quadrupling of CO2 plus reduction in total solar irradiance

Record identifier : f16e30e2-dd9e-11e6-b89b-ac72891c3257

Description : Beginning from a preindustrial control simulation (picontrol) the net top of atmosphere (TOA) radiative flux imbalance due to an abrupt quadrupling of the CO2 concentration (abrupt4xCO2) would be balanced via a reduction in total solar irradiance. Here, "balance" is defined as the global mean value of top-of-atmosphere net radiative flux being within +-0.1 W/m2 of the piControl experiment over an average of years 1-10 of the simulation. The G1 experiment should be run for 50 years, however modelling groups that are not able to extend their previous (G1) model simulation should run the CMIP6 G1 experiment for the full 100 years.
