Abstract-Ambient concentrations of reactive nitrogen compounds as well as total NO, were measured
during June and early July 1992 at a rural site, site SONIA, in the central Piedmont region of North
Carolina as a part of the Southern Oxidants Study. The measurements of reactive nitrogen species were
made in an effort to provide a comprehensive understanding of nitrogen chemistry and to investigate the
total nitrogen budget at the site. NO, NO, and NO showed diurnal variations with maxima in the morning
between 0600 and 0900 EST. The maximum NO,, concentration reached was _ 14.5ppbv, and the
maximum concentrations of NO and NO, were 5.4 and 7.8 ppbv, respectively. The mean NO, mixing ratio
