Abstract

The concentrations of the HO 2 ‐RO 2 species measured during July 11, 1990, in the ROSE (Rural Oxidants in the Southern Environment) study in Alabama are compared to those expected in theory from calculations based upon detailed hourly measurements of a variety of trace gases including the hydrocarbons, NO, NO 2 , carbonyl compounds, CO, PAN (peroxyacetylnitrate) and calculated j O 3 values. The measurements are also compared with the [HO 2 ] + [RO 2 ] as estimated from deviations from the NO 2 + hv (+O 2 ) ⇄ NO + O 3 photostationary state. Within the error of the measurements all of the data appear to be in reasonable accord.
