“…Calculation of non-stomatal sinks, in conjunction with an ecosystemspecific calculation of vertical O 3 profiles, is an important part of this calculation, as discussed in Tuovinen et al (2004Tuovinen et al ( , 2009 or Simpson et al (2003). The methodology and robustness of the calculations of O 3 deposition and stomatal conductance have been explored in a number of publications (Tuovinen et al, 2004(Tuovinen et al, , 2009Emberson et al, 2007;Büker et al, 2012). …”

Abstract. Eleven of the world's 20 most polluted cities are located in India and poor air quality is already a major public health issue. However, anthropogenic emissions are predicted to increase substantially in the short-term (2030) and medium-term (2050) futures in India, especially if no further policy efforts are made. In this study, the EMEP/MSC-W chemical transport model has been used to predict changes in surface ozone (O 3 ) and fine particulate matter (PM 2.5 ) for India in a world of changing emissions and climate. The reference scenario (for present-day) is evaluated against surfacebased measurements, mainly at urban stations. The evaluation has also been extended to other data sets which are publicly available on the web but without quality assurance. The evaluation shows high temporal correlation for O 3 (r = 0.9) and high spatial correlation for PM 2.5 (r = 0.5 and r = 0.8 depending on the data set) between the model results and observations. While the overall bias in PM 2.5 is small (lower than 6 %), the model overestimates O 3 by 35 %. The underestimation in NO x titration is probably the main reason for the O 3 overestimation in the model. However, the level of agreement can be considered satisfactory in this case of a regional model being evaluated against mainly urban measurements, and given the inevitable uncertainties in much of the input data.For the 2050s, the model predicts that climate change will have distinct effects in India in terms of O 3 pollution, with a region in the north characterized by a statistically significant increase by up to 4 % (2 ppb) and one in the south by a decrease up to −3 % (−1.4 ppb). This variation in O 3 is assumed to be partly related to changes in O 3 deposition velocity caused by changes in soil moisture and, over a few areas, partly also by changes in biogenic non-methane volatile organic compounds.Our calculations suggest that PM 2.5 will increase by up to 6.5 % over the Indo-Gangetic Plain by the 2050s. The increase over India is driven by increases in dust, particulate organic matter (OM) and secondary inorganic aerosols (SIAs), which are mainly affected by the change in precipitation, biogenic emissions and wind speed.The large increase in anthropogenic emissions has a larger impact than climate change, causing O 3 and PM 2.5 levels to increase by 13 and 67 % on average in the 2050s over the main part of India, respectively. By the 2030s, secondary inorganic aerosol is predicted to become the second largest contributor to PM 2.5 in India, and the largest in the 2050s, exceeding OM and dust.

“…Several studies have shown that, in northern temperate woody species, current and elevated O 3 concentrations induce significant reductions in photosynthesis [5,6] and shifts in carbon allocation [2,7]. For conifer or needle plants, O 3 -induced reductions in photosynthesis have been reported for Norway spruce (Picea abies) [8,9] and different pine species such as ponderosa pine (Pinus ponderosa) [10,11], Scots pine (Pinus sylvestris) [12,13] and loblolly pine (Pinus taeda) [14].…”

a b s t r a c tOne-year-old Metasequoia glyptostroboides seedlings were exposed to non-filtered ambient air (NF) and elevated ozone (E-O 3 , NF + 60 ppb) in open-top chambers for two years. E-O 3 accelerated leaf senescence, as indicated by significant decreases in photosynthetic pigment contents with the elongation of O 3 exposure. E-O 3 significantly affected gas exchange and carboxylation, inducing reductions in light-saturated photosynthesis (A sat ), the maximum activity of Rubisco (V c,max ) and the maximum electron transport rate (J max ). Chl a/b, V c,max /J max and stomatal limitation (l) were not affected. Stomatal conductance (g s ) was significantly decreased by E-O 3 in the first year, but remained unchanged in the second year. It can be inferred that the decrease in A sat by E-O 3 was mainly attributed to the changes in non-stomatal factors. After two years' exposure, E-O 3 caused significant decreases in canopy photosynthesis and leaf mass per area, and a significant increase in the number of branches, but induced slight, not significant decreases in growth and biomass. Therefore, it can be concluded that the carbon accumulation of the species M. glyptostroboides could be negatively affected after long-term exposure to high O 3 concentration.
