NO2 Levels in Croatian Air from 1992 to 2001

This paper deals with the annual course of NO2 mean daily concentrations, measured in the stations of Puntjarka and Zavižan, which operate according to the EMEP Program, and are compared to the measurements in the station of the Zagreb-Maksimir urban area. The impact of traffic on the NO2 daily concentration level for the Zagreb urban area has been determined through the weekly course of NO2 concentration levels per season and in a year. During the period of significant increase of NO2 concentration in the Zagreb urban area, meteorological factors have been analysed, as they are one of the indicators for the efficiecy of both the increase and decrease of NO2 daily concentration levels.
