Modeling the regional impact of ship emissions on NOx and ozone levels over the Eastern Atlantic and Western Europe using ship plume parameterization
ship emissions NOx ozone levels the Eastern Atlantic Western Europe ship plume parameterization
2010/8/16
In general, regional and global chemistry transport models apply instantaneous mixing of emissions into the model's finest resolved scale. In case of a concentrated source, this could result in errone...
A review of the theoretical basis for bulk mass flux convective parameterization
the theoretical basis bulk mass flux convective parameterization
2010/8/12
Most parameterizations for precipitating convection in use today are bulk schemes, in which an ensemble of cumulus elements with different properties is modelled as a single, representative entraining...
Parameterization of subgrid plume dilution for use in large-scale atmospheric simulations
Parameterization subgrid plume dilution large-scale atmospheric simulations
2010/3/16
A new model of plume dynamics has been developed for use as a subgrid model of plume dilution in a large-scale atmospheric simulation. The model uses mean wind, shear, and diffusion parameters derived...

2009/1/15
In order to incorporate the effect of gravity waves (GWs) on the atmospheric circulation most global circulation models (GCMs) employ gravity wave parameterization schemes. To date, GW parameterizatio...
Ozonolysis of α-pinene: parameterization of secondary organic aerosol mass fraction
α-pinene secondary organic aerosol mass fraction
2008/12/15
Existing parameterizations tend to underpredict the α-pinene aerosol mass fraction (AMF) or yield by a factor of 2–5 at low organic aerosol concentrations (<5 µg m−3). A wide range of smog...
