“…These observations are in agreement with our study as (Z)--ocimene and (E)--ocimene were the main emitted compounds during fungal pathogen infection, apart from -farnesene. To date, there is only limited number of studies on BVOC emissions from Fraxinus excelsior and none of them reported emission from this tree species [24][25][26]. The present study provides preliminary results on BVOC emissions from Fraxinus excelsior under ambient conditions.…”

“…Since the simulated land cover changes exhibited large differences in different dynamic vegetation models (Cramer et al, 2001), a growing number of studies on BVOC emissions used LCLU datasets derived from satellite observation and land survey (Gulden et al, 2008;Smiatek et al, 2009;Leung et al, 2010;Zemankova and Brechler, 2010;Zheng et al, 2010;Wang et al, 2011a). Gulden et al (2008) compared simulated 1993Á1998 biogenic emissions over Texas, USA, using survey-derived plant functional type (PFT) with those using satellite-derived PFT, and found that the statewide mean monthly BVOC emission from the former approach was three times the value from the latter one.…”

A B S T R A C T Based on the MEGAN (Model of Emissions of Gases and Aerosols from Nature) module embedded within the global chemical transport model (GEOS-Chem), we estimate the changes in emissions of biogenic volatile organic compounds (BVOCs) and their impacts on surface-layer O 3 and secondary organic aerosols (SOA) in China between the late 1980s and the mid-2000s by using the land cover dataset derived from remote sensing images and land use survey. The land cover change in China from the late 1980s to the mid-2000s can be characterised by an expansion of urban areas (the total urban area in the mid-2000s was four times that in the late 1980s) and a reduction in total vegetation coverage by 4%. Regionally, the fractions of land covered by forests exhibited increases in southeastern and northeastern China by 10Á30 and 5Á15%, respectively, those covered by cropland decreased in most regions except that the farmingÁpastoral zone in northern China increased by 5Á20%, and the factions of grassland in northern China showed a large reduction of 5Á30%. With changes in both land cover and meteorological fields, annual BVOC emission in China is estimated to increase by 11.4% in the mid-2000s relative to the late 1980s. With anthropogenic emissions of O 3 precursors, aerosol precursors and aerosols fixed at year 2005 levels, the changes in land cover and meteorological parameters from the late 1980s to the mid-2000s are simulated to change the seasonal mean surface-layer O 3 concentrations by (4 to '6 ppbv ((10 to '20%) and to change the seasonal mean surface-layer SOA concentrations by (0.4 to '0.6 mg m (3 ( (20 to '30%) over China. We find that the decadal changes in meteorological parameters had larger collective effects on BVOC emissions and surface-layer concentrations of O 3 and SOA than those in land cover and land use alone. We also perform a sensitivity simulation to compare the impacts of changes in anthropogenic emissions on concentrations of O 3 and SOA with those of the changes in meteorological parameters and land cover.

“…As compared to some other woody species, such as poplar or beech, spruce is a lower BVOC emitter (Bortsoukidis et al, 2014); however, it is still known to emit considerable amounts of reactive trace gases, and is considered particularly as an emitter of monoterpenes, such as α-pinene, β-pinene, limonene, and myrcene, whereas it is only a low isoprene emitter (Esposito et al, 2016;Jurán et al, 2017). Though some indicative information exists on BVOC emission for the CR (Zemankova and Brechler, 2010;Jurán et al, 2017), observation-based data in high time-resolution suitable for use in our model are lacking at present. Nevertheless, it would be very interesting in the future to include the data on BVOC concentration to observe how they influence our model.…”

The aim of our study was to identify the factors substantially affecting day-to-day variability in O 3 concentrations in Czech mountain forests and to describe their influence in detailed, quantitative way. We examined the effects of meteorology and ambient NO x recorded in regular long-term continuous monitoring at five mountain forest sites representing different regions, covering both polluted and relatively unpolluted areas over the time period of 1992-2018. To investigate the association between ambient O 3 concentrations on one hand, and precursor NO x concentrations, and meteorology on the other hand, we used a generalized additive model, GAM, with semiparametric (penalized-spline-based) components to capture properly the possible departures from linearity that is not captured by traditional linear regression approaches. Our results revealed that the O 3 concentrations showed significant associations with all selected explanatory variables, i.e., air temperature, global solar radiation (GLRD), relative humidity, and NO x . Apparently, both meteorology and air pollution are highly important for day-to-day O 3 concentrations, and this finding is consistent for all five rural sites, representing middle-elevated forested mountain areas in Central Europe. In addition to individual variables, we were able to detect interactions between three pairs of explanatory variables, namely temperature * GLRD, temperature * relative humidity, and GLRD * relative humidity. Moreover, we confirmed non-linear O 3 behavior toward all individual explanatory variables.
