“…Measurements performed at the Montsouris Observatory close to Paris from 1876 to 1912 using a solution chemistry method show low O 3 concentrations (10-15 ppbv) in the planetary boundary layer (PBL) [Volz and Kley, 1988]. Similar measurements were conducted from 1956-1983 at Arkona, a coastal site on the Baltic Sea [Feister and Warmbt, 1987], and the series was continued at the nearby Zingst site (Figures 2.7 and 2.8). The earliest springtime measurements at Arkona show O 3 concentrations around 15 ppbv followed by an increase (amounting to about 20 ppbv) to the present Zingst concentrations.…”

“…The data sets discussed here suggest that this trend has continued at similar rates up to the present time. This comparison can only be semi-quantitative since the sites are not directly comparable -Montsouris was a continental site on the outskirts of Paris, and Arkona is located on the island of Rügen in the Baltic Sea (data originally reported by Feister and Warmbt, 1987). Also, these historical data represent 24-h averages of all measurements, while both data sets discussed in this paper are selected for background conditions.…”

Increasing ozone in marine boundary layer inflow at the west coasts of North America and Europe

Abstract. An effective method is presented for determining the ozone (O 3 ) mixing ratio in the onshore flow of marine air at the North American west coast. By combining the data available from all marine boundary layer (MBL) sites with simultaneous wind data, decadal temporal trends of MBL O 3 in all seasons are established with high precision. The average springtime temporal trend over the past two decades is 0.46 ppbv/yr with a 95% confidence limit of 0.13 ppbv/yr, and statistically significant trends are found for all seasons except autumn, which does have a significantly smaller trend than other seasons. The average trend in mean annual ozone is 0.34±0.09 ppbv/yr. These decadal trends at the North American west coast present a striking comparison and contrast with the trends reported for the European west coast at Mace Head, Ireland. The trends in the winter, spring and summer seasons compare well at the two locations, while the Mace Head trend is significantly greater in autumn. Even though the trends are similar, the absolute O 3 mixing ratios differ markedly, with the marine air arriving at Europe in all seasons containing 7±2 ppbv higher ozone than marine air arriving at North America. Further, the ozone mixing ratios at the North American west coast show no indication of stabilizing as has been reported for Mace Head. In a larger historical context the background boundary layer O 3 mixing ratios over the 130 years covered by available data have increased substantially (by a factor of two to three), and this increase continues at present, at least in the MBL of the Pacific coast region of North America. The reproduction of the increasing trends in MBL O 3 over the past two decades, as well as the difference in the O 3 mixing ratios between the Correspondence to: D. D. Parrish (david.d.parrish@noaa.gov) two coastal regions will present a significant challenge for global chemical transport models. Further, the ability of the models to at least semi-quantitatively reproduce the longerterm, historical trends may an even greater challenge.

“…Long time-series of ozone measurements in Europe show that the concentration of ozone has been increasing not only in the air near the Earth's surface ("wet chemical method" : Feister and Warmbt, 1987; "Schönbein method": Volz and Kley, 1998), but also in the free troposphere ("ozone balloon soundings": Staehelin and Schmid, 1991; "ground-based UV-photometers": Staehelin et al, 1994; "Schönbein method" and "UV-absorption analyser" Marenco et al, 1994). These results have been taken as evidence of an increase in the photochemical production of ozone in the atmosphere due to the growing emissions of ozone precursors.…”

Abstract. Several thousands of ozone vertical profiles collected in the course of the MOZAIC programme (Measurements of Ozone, Water Vapour, Carbon Monoxide and Nitrogen Oxides by In-Service Airbus Aircraft) from August 1994 to February 2002 are investigated to bring out climatological and interannual variability aspects. The study is centred on the most frequently visited MOZAIC airports, i.e. Frankfurt (Germany), Paris (France), New York (USA) and the cluster of Tokyo, Nagoya and Osaka (Japan). The analysis focuses on the vertical integration of ozone from the ground to the dynamical tropopause and the vertical integration of stratospheric-origin ozone throughout the troposphere. The characteristics of the MOZAIC profiles: frequency of flights, accuracy, precision, and depth of the troposphere observed, are presented. The climatological analysis shows that the Tropospheric Ozone Column (TOC) seasonal cycle ranges from a wintertime minimum at all four stations to a spring-summer maximum in Frankfurt, Paris, and New York. Over Japan, the maximum occurs in spring presumably because of the earlier springtime sun. The incursion of monsoon air masses into the boundary layer and into the mid troposphere then steeply diminishes the summertime value. Boundary layer contributions to the TOC are 10% higher in New York than in Frankfurt and Paris during spring and summer, and are 10% higher in Japan than in New York, Frankfurt and Paris during autumn and early spring. Local and remote anthropogenic emissions, and biomass burning over upstream regions of Asia may be responsible for the larger low-and mid-tropospheric contributions to the tropospheric ozone column over Japan throughout the year except during the summer-monsoon season. A simple Lagrangian analysis has shown that a minimum of 10% of the TOC is of stratospheric-origin throughout the year. Investigation of the short-term trends of the TOC over the period [1995][1996][1997][1998][1999][2000][2001] Correspondence to: R. M. Zbinden (zbir@aero.obs-mip.fr) shows a linear increase 0.7%/year in Frankfurt, 0.8%/year in Japan, 1.1%/year in New York and 1.6%/year in Paris for the reduced 1995-1999 period. Dominant ingredients of these positive short-term trends are the continuous increase of wintertime tropospheric ozone columns from 1996 to 1999 and the positive contributions of the mid troposphere whatever the season.
