Experimental investigations on urban air pollution caused by motor-traffic have taken place in Munich, a super-city in the southern part of Germany. From sum- mer 1990 through spring 1993, stationary and non-stationary measurements of the Classical" near-to-ground air pollutants NO, NC^, O, and CO were taken in a mobile measuring system. This consisted of a van with gas analysers together with a trailer for the power supply. The results, presented in this article, show the dependence of air pollution levels upon traffic density, meteorological condi- tions, urban structures, street canyon situations and various vehicular tunnels. 1 Introduction The dispersion and dilution of air pollutants emitted by vehicles is one o
