Uncertainty assessment of current size-resolved parameterizations for below-cloud particle scavenging by rain
current size-resolved parameterizations below-cloud particle rain
2010/8/13
Current theoretical and empirical size-resolved parameterizations of the scavenging coefficient (Λ), a parameter commonly used in aerosol transport models to describe below-cloud particle scavenging b...
Uncertainties in atmospheric chemistry modelling due to convection parameterisations and subsequent scavenging
atmospheric chemistry modelling parameterisations subsequent scavenging
2010/2/21
Moist convection in global modelling contributes significantly to the transport of energy, momentum, water and trace gases and aerosols within the troposphere. Since convective clouds are on a scale t...

2010/2/21
A diagnostic cloud nucleation scavenging scheme, which determines stratiform cloud scavenging ratios for both aerosol mass and number distributions, based on cloud droplet, and ice crystal number conc...
Aerosol size-dependent below-cloud scavenging by rain and snow in the ECHAM5-HAM
size-dependent below-cloud scavenging rain snow ECHAM5-HAM
2009/7/23
Wet deposition processes are highly efficient in the removal of aerosols from the atmosphere, and thus strongly influence global aerosol concentrations, and clouds, and their respective radiative forc...

Technical note: A new comprehensive SCAVenging submodel for global atmospheric chemistry modelling
comprehensive SCAVenging submodel global atmospheric chemistry modelling
2009/1/4
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 ...
Model sensitivity studies regarding the role of the retention coefficient for the scavenging and redistribution of highly soluble trace gases by deep convective cloud systems
