The radiative effect due to aerosol-radiation interactions (REari) of biomas burning (BB) aerosol in the CAM5.4 sensitivity tests. The CAM5.4 sensitivity tests are for different BB aerosol treatments: default CAM5.4 (CAM5.4), CAM5.4 with decreased BB black carbon refractive index (CAM_BCRI), CAM5.4 with increased BB aerosol size (CAM_Dg160), CAM5.4 with externally mixed, fresh BB aerosol (CAM_EMIX), and CAM5.4 with all of the previous changes (CAM_ALL). These REari are considered over the entire globe, the tropics, and the Arctic. Standard deviations from the 5 ensemble means are included.
