Course Outline:

Air Pollution in an Urban Environment


Instructor: Travkin, V.S.

Objective of the Course:
The course will be given as one, which empowers students with knowledge and discuss' the problems in urban air pollution starting from the traditional meteorological science point of view to proceed along with the hierarchical heterogeneous urban environment air pollution theory description.

Tentative outline:
The basic meteorologically backed formulation of the pollution distribution in an urban environment and overview of models will be suggested first. The important issues of distribution of hazardous and terrorism act locally introduced toxic gaseous compounds in heterogeneous urban environment will be introduced next. One of such important topics is the definition of the point, local, and meaningful measured concentration values of harmful agents.

The background and analysis of one scale urban air pollution problems as well as advanced two- and three scale convective diffusion of hazardous compounds in urban environment will be taught. Shown the very different nature of homogeneous and heterogeneous mode descriptions in urban meteorology.

It is natural that problems of atmospheric diffusion and heat pollution in large urban settlements can be formulated with an allowance for the interaction of the atmospheric turbulent boundary layer (ABL) with an underlying surface consisting of urban roughness layer (URL) obstacles. In order to determine and choose a model for turbulent transfer in a URL medium and over it in an ABL, it is necessary to distinguish specific types of models. An understanding of the ways the two- and three phase URL phenomena of transport have to be modeled with the VAT scaled approach, which originally was developed for vastly different scale and physical phenomena, was the opening point in development of turbulent transport scaled modeling in porous media and URL. Few multiscale formulation phenomena in urban rough layer air pollution will be introduced and explained.

Introductory to the urban environment morphology statistics and meteorological experiments set-ups in metropolitan areas will be taught with examples. Will be discussed the connection to the urban architecture mapping and communications between morphometric urban databases and development of the hazardous leakage or terrorist attack first response emergency plans.
