“…Although the importance of isoprene at urban, regional, and global scales of atmospheric chemistry is well established (Fehsenfeld et al, 1992;Guenther et al, 1995;Cowling et al, 1998;Guenther et al, 2000;Fuentes et al, 2000), in many cases, an accurate representation of isoprene and other biogenic hydrocarbons is very limited. In rural areas, isoprene is almost always the dominant reactive hydrocarbon.…”

“…They are a key component of the photochemical processes that form ozone and other secondary products including organic acids, organic nitrates, aerosols etc. in the troposphere (Kasting and Singh, 1986;Trainer et al, 1987;Chameides et al, 1988;Fehsenfeld et al, 1992;Andreae et al, 1997). Today, it is a well-known that they are highly reactive towards hydroxyl and nitrate radicals and ozone and in the presence of nitrogen oxides they contribute to ozone and aerosol formation.…”

“…The basis of the BEIS-2 calculation for soil NO emissions originate with the following equation (Williams et al, 1992): A large number of emission factors based on field measurement data are given in the literature. Williams et al (1992), Yienger and Levy (1995) and Skiba et al (1997) provide excellent reviews on these data.…”

“…fertilized agricultural fields > grasslands > forests > other natural systems is in broad accordance with the nitrogen status of corresponding soils (Ludwig et al, 2001). According to present knowledge, NO is produced in soils nearly ubiquitously; therefore soil emissions constitute a continuous background flux of NO to the atmosphere (Williams et al, 1992). Although soils are usually net sources for atmospheric NO, they can also act as sink, at least temporarily (Slemr and Seiler, 1984).…”

Ambient concentrations of photochemical oxidants (O3, PAN, HNO3, H2O2) and various trace species including reactive nitrogen compounds as well as total NOy were measured during June and early July 1992 at a rural site, SONIA, in the central Piedmont region of North Carolina, as a part of the Southern Oxidants Study. The measurements were made in an effort to provide a comprehensive understanding of tropospheric photochemistry in the rural Southeastern United States. NOy, NO2, and NO showed diurnal variations with maxima in the morning between 0600 and 0900 EST. The maximum NOy, NO, and NO2 concentrations reached were 14.5, 5.4, and 7.8 ppbv, respectively. The mean NOy concentration was found to be 2.63 ± 1.72 ppbv (n = 819) with an average daily maximum of 3.6 ppbv. The mean concentrations of NO and NO2 for the entire period of measurement were found to be 0.18 ± 0.37 ppbv (n = 794) and 1.31 ± 0.99 ppbv/(n = 769). H2O2, HNO3, and PAN showed diurnal variation with maxima in the afternoon and minima at night. Mean concentrations were found to be 0.52 ± 0.36 ppbv (n = 312), 0.67 ± 0.33 ppbv (n = 250), and 0.41 ± 0.24 ppbv (n = 578). The NOx/NOy ratio was used as an indicator of the chemical age of airmasses and the ratio showed strong positive correlations with the photochemical oxidants HNO3 (r = 0.76), PAN (r= 0.68), and O3 (r = 0.79) measured at the site. The relationship between the accumulation rate of O3 and the deviation from the photostationary state was examined based on the measured PSS constant obtained from the values of [O3], [NO], and [NO2] measured at the site.
