Sažetak
Zagreb, the capital of Croatia, has one of the longest history of surface ozone measurements in Europe. Early measurements have been done from 1889 – 1900 by Andrija Mohorovičić, 1 the discoverer of the Moho layer (discontinuity in Earth`s mantle), who used Schönbein’ s method. In the 20th century measurements performed in 1975 in the city centre at 110 m a.s.l. indicated that within that time gap ozone concentration in Zagreb must at least have doubled.2 A statistical analysis of the later data which showed pronounced diurnal variation based on correlation with meteorological variables also connected particularly high ozone values with slow SE wind, i.e., transport from the city`s industrial and airport site.3 Later ozone measurements performed at the elevated RBI station (180 m a.s.l., the Ruđer Bošković Institute) in residential northern part of Zagreb revealed much less influence of these high ozone levels produced in the south. Measurements at the stations Medvedgrad and Puntijarka at 580 m and 980 m a.s.l., respectively, on the mountain Medvednica north above Zagreb also showed that the inversion layer rarely reaches 500 m and never 980 m.4, 5 Therefore, the latter has been chosen as an EUROTRAC-TOR station6 to represent the regional free atmosphere in the corresponding network of stations from 1989-2002. Measurements are still being continued there. Here we report an effort to investigate for summer 2006 the dependence of ozone production, destruction and transport at three same elevation sites located along the 15 km S – N line on equidistant stations Velika Gorica (VG), Dugave (DUG) and Institute for Medical Research and Occupational Health (IMI) stretching from Zagreb Airport to about 2.5 km north from the city center where the station IMI is located.
