Abstract

The response of ClO concentrations to changes in NO_2 concentrations has been inferred from simultaneous observations of [ClO], [NO], [NO_2] and [O_3] in the mid-latitude lower stratosphere. This analysis demonstrates that [ClO] is inversely correlated with [NO_2], consistent with formation and photolysis of [ClONO_2]. A factor of ten range in the concentration of NO_2 was sampled (0.1 to 1×10^9 mol/cm^3), with a comparable range in the ratio of [ClO] to total available inorganic chlorine (1% ≤ [ClO]/[Cl_y] ≤ 5%). This analysis leads to an estimate of [ClONO_2]/[Cl_y] = 0.12 (×/÷2), in the mid-latitude, lower-stratospheric air masses sampled.
