Correction to CFC‐114 Lifetime and CFC‐115 Lifetime [ 1 ] In Prather and Hsu [2008] we have mistakenly used the overall quenching rate of O( 1 D) from JPL 06‐2 [Sander et al., 2006] to compute the lifetimes of CFC‐114 and CFC‐ 115. As a result, their lifetimes are underestimated. When removing 25% physical quenching for CFC‐114 and 70% for CFC‐115 from the total quenching rate (see notes A48 and A49 in JPL 06‐2), the lifetime is corrected to 190 years for CFC‐114 and to 1020 years for CFC‐115. Table 1 in Prather and Hsu [2008] is revised in this note with correct CFC‐114 and CFC‐115 lifetimes. [ 2 ] Acknowledgments. We thank Vladimir Orkin and Dr. Michael Kurylo for graciously pointing out our misreading in (O 1 D) reaction rate with CFC‐114 and ‐115. References Forster, P. V., P. Artaxo, T. Bernstsen, R.
