Short summary
The paper presents a transport mechanism of SILAM CTM based on an algorithm of M. Galperin. We describe the original scheme and its updates needed for applications to long-living species, complex atmospheric flows, etc. The scheme is connected to vertical diffusion, chemical transformation and deposition algorithms. Quality of the advection routine is evaluated with a large set of tests, which showed performance fully comparable with state-of-the-art algorithms at much lower computational costs.
