The Application of Repro-Modeling to the Analysis of a Photochemical Air Pollution Model.

摘要

Several physical models which simulate the impact of emissions and meteorology on the creation and dispersion of photochemical smog have been developed. This paper explores 'repro-modeling,'the analysis and replication of the input/output characteristics of the model. A study of the application of repro-modeling to the SAI model developed for the Los Angeles Basin is described. The major objectives of the study were threefold: (1) a feasibility test of the repro-modeling approach; (2) a limited interpretation of the implications of the model;and (3) an efficient repro-model program which duplicates input/output relationships of the original model. The repro-model developed is analyzed in a particular application context (i.e.,transportation emission control policy evaluation) and its general implications are discussed. Examples of use of the repro-model,which requires orders of magnitude less computer time than the original model,are provided.
