A comparison of integration methods for atmospheric transport-chemistry problems
This paper is devoted to the time integration of atmospheric transport-chemistry problems. Due to the large number of species and the 3D nature off-the-shelf solvers are not feasible. This has led to the use of special techniques. Most popular is operator splitting. This paper presents a comparison between standard operator splitting, source splitting and approximate matrix factorization. All methods under consideration are comparable in costs measured step wise. The comparison is directed at real-life problems. For that purpose a regional air pollution model is used.
