Zonal and annual mean radiative forcing, atmospheric absorption, surface temperature change, and precipitation change for the five PDRMIP drivers.

The left hand panel shows the zonal-annual mean top-of-atmosphere radiative forcing for the five PDRMIP drivers (from top bottom: CO2 in blue, CH4 in cyan, solar in green, BC in red and SO4 in yellow); the individual models are shown (thin lines), in addition to the multi-model mean 737 (thick lines).

The middle panel shows the same but for atmospheric absorption.

The right hand panels show the surface temperature (top) and precipitation changes (bottom) for the multi-model mean for all five drivers (following the color coding from the left and centre  panels). Radiative forcing and atmospheric absorption are diagnosed from the fixed-SST simulations.
