In the report "Spatial variation of ozone depletion rates in the springtime antarctic polar vortex" by Y. L. Yung et al. (11 May, p. 721), the maximum observed value of ClO attributed to J. G. Anderson et al. [J. Geophys. Res. 94, 11465 (1989)] (p. 723) was incorrect. The observed maximum ClO mixing ratio was ∼1.2 x 10-9 (by volume) throughout the flight sequence from 23 August through 22 September 1987 at ER-2 cruise altitude (potential temperature ∼440 K).
