Abstract
The response of ClO concentrations to changes in NO2 concentrations has been inferred from simultaneous observations of [ClO], [NO], [NO2] and [O3] in the mid‐latitude lower stratosphere. This analysis demonstrates that [ClO] is inversely correlated with [NO2], consistent with formation and photolysis of [ClONO2]. A factor of ten range in the concentration of NO2 was sampled (0.1 to 1×109 mol/cm³), with a comparable range in the ratio of [ClO] to total available inorganic chlorine (1% ≤ [ClO]/[Cly] ≤ 5%). This analysis leads to an estimate of [ClONO2]/[Cly] = 0.12 (×/÷2), in the mid‐latitude, lower‐stratospheric air masses sampled.This publication has 18 references indexed in Scilit:
