Abstract

Air pollution is related with numerous different physical, chemical and meteorological phenomena. So, the atmospheric equilibrium depends on hundreds of chemical species, but only few of them are directly emitted and considered as main pollutants. All the others are trace constituents, being nevertheless of outstanding importance for the chemical dynamics in the atmosphere. Since, e.g. smog situations do not only depend on the occurring emissions but also in a crucial way on the meteorological situation, the physical dynamics in the atmosphere are of the same importance for the description of air pollution as the chemical aspects. For those reasons, atmospheric physics, chemistry and meteorology must each contribute in an interdisciplinary manner in order to find adequate solutions for a given problem. As a consequence, the old conventional techniques of air pollution control do no longer meet our needs. Therefore, remote sensing techniques have more and more been put to use. And now, after years of scientific and technical development, some of them are ready for routine measurements [1]. Thus, complex phenomena like urban smog or acid rain can be investigated by continous monitoring on a large and 3D scale.
