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.
