Influences of in-cloud aerosol scavenging parameterizations on aerosol concentrations and wet deposition in ECHAM5-HAM

forested boundary layer produces ultrafine aerosol concentrations and cloud droplet burdens that are more consistent with observations than cluster activation as the sole

The well- predicted aerosol quantities, such as aerosol number, mass composition and optical properties, and the inclusion of full aerosol-cloud couplings lead to
