“…In the lower troposphere ozone is considered a dangerous pollutant that negatively influencing human health and ecosystems (EPA, 2006;Gurjar et al, 2010), being a key constituent of urban smog. Ozone in the troposphere is the third most important greenhouse gas (Fuhrer and Booker, 2003;Forster et al, 2007). While the level of tropospheric ozone in Europe and North America has decreased since the 1980's due to the reduction of precursor emissions [for example, NO x (classically defined as NO + NO 2 ) and volatile organic compounds (VOC)], it continues to increase in the Asian region (Jonson et al, 2006).…”

The variability of total column ozone (TCO) and tropospheric column ozone (TrCO) was examined in Central Asia. Measurements were conducted at the Lidar Station Teplokluchenka in eastern Kyrgyzstan for one year, July 2008-July 2009.TCO was obtained using a handheld Microtops II Ozonometer (TCO-MII) and from the Aura OMI (TCO-OMI) satellite. Nitrogen dioxide (NO 2 ) and formaldehyde concentrations also were obtained from the OMI satellite. Formaldehyde was used as a surrogate for volatile organic compounds. TrCO was estimated by the difference between TCO-OMI and stratospheric column ozone retrieved from the MLS satellite. Comparison of the ground-based TCO-MII with TCO-OMI showed good agreement (r 2 = 0.93), and linear regression between these was used to estimate missing values in the TCO-MII dataset. The contribution of TrCO to TCO varied from 15% in summertime to 5% in winter. High values of TrCO were observed during summer (July: 45 DU) and low values during winter (December: 15 DU), as is typically observed. The average values of TrCO for summer, autumn, winter, and spring were equal to 42, 27, 20, and 30 DU, respectively. Seasonal variability of TrCO corresponded to solar intensity, indicating that TrCO is likely to form through photochemical means rather than stratospheric intrusion.The spatial distribution of NO 2 and VOC were examined to better understand the regional sources of these ozone precursors. Transport from highly populated areas of the Ferghana Valley and Tashkent in Uzbekistan contributed to the TrCO concentrations observed in this work. The HCHO/NO 2 ratio, an indicator of the ozone production rate, suggested that reducing NO 2 would be more effective in reducing TrCO during most of the year, except summer, when reductions of both would likely be needed.

“…Ozone (O 3 ) is currently the most important air pollutant that negatively affects growth of both agricultural and native species in most parts of the world (Ashmore, 2005;Benton et al, 2000;Clarke et al, 1990;Fuhrer and Booker, 2003;Karnosky et al, 2007;Krupa et al, 2001;Wang et al, 2007a). Limited measurements suggest that pre-industrial ground-level O 3 concentration ([O 3 ]) was about 10 ppb (Volz and Kley, 1988).…”

“…Then it reacts with lipid and protein components of cell walls and plasma membranes, leading to formation of aldehydes, peroxides and assorted reactive oxygen species (Lindroth 2010). These products can then activate various transduction pathways for defence responses: stomatal closure, production of anti-oxidants such as ascorbate, phenolics (Lindroth 2010) and isoprenoids (Loreto et al, 2004), and programmed cell death (Fuhrer & Booker 2003;Valkama et al, 2007). Therefore, O 3 can influence both ecosystem structure and functions (Heagle 1989;Heagle et al, 1999;Ashmore 2005;Muntifering et al, 2006).…”

The impact of ozone (O 3 ) on European vegetation is largely under-investigated, despite huge areas of Europe are exposed to high O 3 levels and which are expected to increase in the next future. We studied the potential effects of O 3 on photosynthesis and leaf area index (LAI) as well as the feedback between vegetation and atmospheric chemistry using a land surface model (ORCHIDEE) at high spatial resolution (30 km) coupled with a chemistry transport model (CHIMERE) for the whole year 2002. Our results show that the effect of tropospheric O 3 on vegetation leads to a reduction in yearly gross primary production (GPP) of about 22% and a reduction in LAI of 15-20%. Larger impacts have been found during summer, when O 3 reaches higher concentrations. During these months the maximum GPP decrease is up to 4 g C m À2 day À1 , and the maximum LAI reduction is up to 0.7 m 2 m À2 . Since CHIMERE uses the LAI computed by ORCHIDEE to estimate the biogenic emissions, a LAI reduction may have severe implications on the simulated atmospheric chemistry. We found a large change in O 3 precursors that however leads to small changes in tropospheric O 3 concentration, while larger changes have been found for surface NO 2 concentrations.
