The photochemical reaction mechanisms used in regional air quality models usually consider 20 to 100 pollutant species. The equations resulting from these chemical mechanisms are nonlinear, highly coupled and extremely stiff depending on the time of the day. Therefore, the simulation time of the models is determined to a large degree by the computational burden associated with the solution of the chemistry equations.
