“…The results in Figure 4 and Table III slightly differ from results given earlier (Feister and Warmbt, 1985), because some of the ozone values which seemed to be unreliable were rejected in the present analysis. As the annual mean ozone values shown at the bottom of Figure 4 were determined from daily mean values, they may also be somewhat different from those of Figure 3 which were obtained from monthly mean values.…”

“…Due to the low SO2 concentration of about 10/.tg m -3 (3.5 ppbv) at the remote sea-shore station Arkona, there is no interference by SO2 at Arkona prior to 1972. Therefore, the Arkona record appeared to be suitable for an analysis of long-term trends (Feister and Warmbt, 1985).…”

“…It has also been suggested that different amounts of the ozone trend in the summer months can be ascribed to different amounts of trends in global radiation, which may be caused by limited different trends of cloudiness (Feister and Warmbt, 1985). Particularly, such dry and hot summer months as in 1976 and in 1982 showed high values of surface ozone (Attmannspacher, 1983).…”

The ozone concentration near the earth's surface has been measured at some stations in the GDR for more than 30 yr using the wet chemical method. Even at rural stations the ozone data show a significant linear increase by about 1-3% yr -~ . The ozone increase being stronger in summer than in winter is assumed to be due to photochemical ozone production from increasing anthropogenic emissions of trace gases that are transported over long distances. A weaker ozone increase by only about 0.2% per year was observed in the free troposphere (5.5 km) from balloon-soundings at Lindenberg within the period 1975-1984. If the ozone trends continue, the ozone concentration near the surface and its seasonal amplitude will have doubled around the turn of the century as compared to the mid-fifties.

“…Since 1982, surface ozone at the site has been continuously recorded using the ozonograph II instrument, which has an accuracy of ±2 percent for 30-minute averages. 30 Table IV summarizes the percentile distribution of the hourly ozone concentrations for the period [1984][1985][1986][1987][1988][1989][1990]. In 1983, data recovery was less than 70 percent at the site.…”

“…From industrialized regions, trends of the order 1% yr -1 have been documented (Attmannspacher et al, 1984;Feister and Warmbt, 1985;Bojkov and Reinsel, 1985;Logan, 1986).

During the past decade (1977)(1978)(1979)(1980)(1981)(1982)(1983)(1984)(1985)(1986) ozone has been measured on board various research vessels between 83°N and 76 ° S. The latitudinal distribution shows nearly twice as high an ozone concentration in the Northern Hemisphere (30 ppb) as compared to the Southern Hemisphere (15 ppb). North of 70"N the concentration rapidly drops to low values (17 ppb). In the ITCZ we frequently observed a pronounced secondary maximum which indicates that tropospheric-stratospheric exchange may be induced by deep convection. During other occasions, ozone concentrations below 10 ppb were observed in the ITCZ. Secondary maxima are also found in each hemisphere, indicating the latitudes in which stratospheric-tropospheric exchange occurs. One such pronounced maximum is found between 60 and 65 ° N. A comparable counterpart does not, however, occur in the respective southern latitudes.The observations, although incomplete, allow for conclusions with respect to seasonal cycles, at least in some of the latitudes or for some part of the year. In the tropics differences between continental and maritime yearly cycles are found. In mid to high northern latitudes, a sharp maximum is found which extends to the summer months over continental European sites. In the respective southern latitudes, such a spring maximum is only indicated.Comparison with occasionally concurrent Kr 85 measurements by other groups allows for the conclusion that in some cases photochemically produced ozone in polluted air masses is seen over the Atlantic ocean.
