Abstract. We present the new scavenging scheme SCAV, simulating the removal of
trace gases and aerosol particles by clouds and precipitation in global
atmospheric chemistry models.
The scheme is quite flexible and can be used for various purposes, e.g.
long term chemistry simulations as well as detailed cloud and precipitation
The presence of clouds can substantially change the chemical
composition of the atmosphere.
We present a new method of mechanistically coupling gas phase, aerosol, cloud
and precipitation chemistry, which enables studies of feedbacks between
multiphase chemistry and transport processes.
