This dataset contains model output data for radiative fluxes, emissions, aerosols and ozone produced from an additional AerChemMIP model experiment where anthropogenic precursor emissions and trace gas constituents were held fixed at 2014 values. This model experiments was conducted by UKESM1, a model contributing to CMIP6, and was run over the period 2015 to 2100 to investigate the effect of anthropogenic emissions on near-term climate forcers. The atmosphere only CMIP6 configuration of UKESM1 was used to run this experiment. Model simulations were conducted at a global resolution of 1.875° x 1.25°.
