Abstract: Different higher-order flux closures are compared for two chemistry cases using a large eddy simulation (LES) model for the convective atmospheric boundary layer. Both a simple chemistry case and a photochemistry case more ...

Abstract: The use of climate simulations in scientific assessments of climate change and in the formulation of climatechange scenarios has been contested for, among others, methodological reasons. The "philosophy of climate ...

Abstract: Covariances and fluxes of reactive species in the clear convective atmospheric boundary layer (CABL) are studied and parameterized. The covariances result from correlations between reactive species. These covariances may ...

Abstract: The transport of nonreactive and reactive bottom-up and top-down diffusing scalars in a solid-lid convective boundary layer is studied using large-eddy simulation (LES). The chemistry considered consists of an irreversible, ...
