描述"Models are often the only way of interpreting measurements to in­ vestigate long-range transport, and this is the reason for the emphasis on them in many research programs". B. E. A. Fisher: "A review of the processes and models of long-range transport of air pollutants", Atmospheric Environment, 17(1983), p. 1865. Mathematical models are (potentially, at least) powerful means in the efforts to study transboundary transport of air pollutants, source-receptor relationships and efficient ways of reducing the air pollution to acceptable levels. A mathematical model is a complicated matter, the development of which is based on the use of (i) various mechanisms describing mathematically the physical and chemical properties of the studied phenomena, (ii) different mathematical tools (first and foremost, partial differenti­ al equations), (iii) various numerical methods, (iv) computers (especially, high-speed computers), (v) statistical approaches, (vi) fast and efficient visualization and animation techniques, (vii) fast methods for manipulation with huge sets of data (input data, intermediate data and output data).

Running Air Pollution Models on Vector Machines,ount of computing time is required to run them on computers. This (together with the fact that the big vector processors are still among the fastest computers that are available at the market) explains why large air pollution models are often run on big vector processors (as, for example, different types of CRAY computers).

Running Models on Massively Parallel Computers,continue in the future. Therefore it may be useful to test the performance of some large application codes on such computers.Of course, large air pollution models must also perform efficiently on massively parallel computers, especially if such computers are available at the particular site where the code is to be run.

Moreover, under certain circumstances the transported air pollutants may lead (directly or indirectly) to some damaging effects on plants,animals and humans. Therefore, it is important to be able to study the LRTAP carefully.Mat

Thus, including more species leads to an increase of the size of the problem. However, even more important is the fact that the system of PDE’s cannot

https://doi.org/10.1007/978-3-031-07414-1ems. Therefore it is crucial to perform efficiently the most time-consuming calculations during the numerical treatment of a large air pollution model. Efficiency can be achieved by selecting numerical algorithms which are both fast and accurate and by implementing correctly these algorithms in the
