above a cloud layer, particularly for marine stratocumulus cloud decks over the regions off the western coasts of continents, the diabatic heating due to aerosol absorption strengthens the inversion and reduces the entrainment rate, causing an enhancement of stratocumulus clouds ( Wilcox 2010 ; Sakaeda et al. 2011 ; Li et al. 2013 ; Yamaguchi et al. 2015 ). Realistic simulations of the various cloud systems are crucial to reduce the uncertainty in quantitative assessment of the aerosol effects on

summary of the main findings in the past about aerosol impacts on warm clouds. Here we focus on the recent findings on the understanding of ACI for warm shallow cumuli and stratocumuli. 1) Aerosol impact on formation and organization of boundary layer clouds Warm boundary layer clouds form by convective processes, which are driven by surface heating and/or by cloud-top radiative cooling. Surface heating tends to form cumuliform clouds, whereas cloud-top radiative cooling creates decks of stratus or

% elemental carbon fraction of PM 2.5 is a lower limit for semidirect radiative effects to be important ( Meier et al. 2012 ), suggesting that absorption and heating by black carbon (i.e., the semidirect effect) would be minimal. Simulated organic carbon aerosol concentrations are also relatively low. Organic aerosol is derived from primary emissions and secondary formation in the atmosphere from anthropogenic species, but the SORGAM SOA module is known to underpredict SOA formation ( Ahmadov et al. 2012
