Abstract

Conventional numerical techniques for integrating the gas-phase chemistry portion of a pollution-transport model tend to require a large amount of processing time to produce a model prediction. Such models often make use of a vectorizing supercomputer in order to generate output in a reasonable amount of time. However, the mathematical methods frequently fail to take advantage of the vectorization capabilities of these computers, with a resultant loss in processing efficiency. Recently, it has been shown that the time required to simulate gas- phase chemistry can be greatly reduced for the case of a highly accurate predictor-corrector method (Jacobson and Turco [1]; Gear [2]). The key
