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...
Long-lived halocarbon trends and budgets from atmospheric chemistry modelling constrained with measurements in polar firn
Long-lived halocarbon atmospheric chemistry modelling polar firn
2009/6/22
The budgets of seven halogenated gases (CFC-11, CFC-12, CFC-113, CFC-114, CFC-115, CCl4 and SF6) are studied by comparing measurements in polar firn air from two Arctic and three Antarctic sites, and ...
Atmospheric impact of the 1783–1784 Laki eruption: Part I Chemistry modelling
Atmospheric impact 1783–1784 Laki eruption Chemistry modelling
2009/3/10
Results from the first chemistry-transport model study of the impact of the 1783–1784 Laki fissure eruption (Iceland: 64°N, 17°W) upon atmospheric composition are presented. The eruption released an e...
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 ...
