Some reduction techniques for simplifying atmospheric chemical kinetics
Résumé
We review in this article some issues related to reduction techniques for atmospheric chemical kinetics. There is indeed a wide range of characteristic timescales for atmospheric chemistry and the time evolution is characterized by a slow-fast behaviour. We present here some related points: the existence of an underlying reduced model, the partitioning techniques to build reduced models, time integration of the reduced models and finally the application of Proper Orthogonal Decomposition (POD) method for reducing chemical systems.
