Abstract |
A technique was developed to establish an optimum meteorological and air pollution sampling network in urban areas. The basis of the network is the wind field in the urban area rather than the air pollution distribution because it provided a solution with longer-term stability than the air pollution distribution. Three specific models are required in order to determine the optimum network. These are: a three-dimensional hydrodynamic model; a statistical model; and an objective variational analysis model. The primitive equation model is used to simulate the wind field for a variety of cases. These simulated data were used to determine the form of a regression model which approximates the various wind fields. A regression model form was then used, along with a set of potential network sites, and a criterion for judging alternative networks to derive the sampling network for the winds. The method used to develop the network involved the successive elimination of candidate sites until a reasonably sized network was achieved. The air pollution distribution is obtained through an objective variational analysis model. The model simultaneously minimizes the error variance by comparing observed pollution concentrations with derived pollution concentrations and the error variance of the constraint equation. |
