  1. All three air quality (AQ) control experiments feature large increases in CO2, but different trajectories of aerosols and precursor gases, and in some cases, methane (i.e., SSP3-7.0-lowNTCFCH4). Mitigation signals are obtained by differencing AQ control experiments. For example, non-methane NTCF (NMNTCF) mitigation is obtained by subtracting the SSP3-7.0-lowNTCF experiment (strong non-methane AQ control) and the SSP3-7.0 experiment (weak AQ control).
