Variance-based sensitivity analysis of the unified Danish Eulerian model according to variations of chemical rates

Abstract

A special computational technology for sensitivity analysis of ozone concentrations according to variations of rates of chemical reactions is developed. It allows us to study a larger number of reactions than we have considered in our previous study. The reactions are taken from the standardized scheme for air-pollution chemistry CBM-IV. A number of numerical experiments with a large-scale air pollution model (Unified Danish Eulerian Model, UNI-DEM) have been carried out to compute Sobol sensitivity measures. The sensitivity study has been done for the areas of four European cities (Genova, Milan, Manchester, and Edinburgh) with different geographical locations. © 2013 Springer-Verlag.
