Global distribution and climate forcing of marine organic aerosol – Part 2: Effects on cloud properties and radiative forcing
A series of simulations with the Community Atmosphere Model version 5 (CAM5) with a 7-mode Modal Aerosol Model were conducted to assess the changes in cloud microphysical properties and radiative forcing resulting from marine organic aerosols. Model simulations show that the anthropogenic aerosol in...
