Abstract: The vertical diffusion of a passive conservative scalar through the convective PBL is actually the superposition of what we call ?top-down? and ?bottom up? processes. These component processes are driven by scalar fluxes ...

Abstract: We compared observed and model-simulated surface concentration on a spatial wale of 1100 km and a temporal scale of 36 h. The Eulerian tracer model calculated advection by the mean winds and gradient transport for subgrid-scale ...
