Running Air Pollution Models on Vector Machines

The long-range transport air pollution models (the LRTAP models) are, as shown in the preceding chapters, extremely complex and, therefore, a great amount 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).
