Abstract

Instantaneous air pollution fields in towns have mosaic structure and to measure its probability function one needs a measuring network with a great number of sensors. The problem cannot be solved purely by means of computer simulations because of the turbulent character of the air flows among buildings. In this paper we studied this problem by using lidar measurements and computer simulations simultaneously. The lidar data was used for the model parameterization. To simulate the atmosphere transport of the pollution puffs over city buildings we developed the special computer trajectory model. It takes into account the processes of plume widening while spreading over obstacles. The method is easily adjusted on the base of a plume geometrical and transparency lidar measurements. It uses the approximation of a quasipotential flow. The model accounts the widening of a plume flowing around buildings through effects of air volumes scattering on the potentials that represent building configurations. This method was used to study air polluted zones from one of Moscow's heat power stations.
