“…In this paper we present and analyze a data set of 10 s (2 km) merged and gap-filled observations of the key reactive species driving the chemical budgets of O<span class="inline-formula">₃</span> and CH<span class="inline-formula">₄</span> (O<span class="inline-formula">₃</span>, CH<span class="inline-formula">₄</span>, CO, H<span class="inline-formula">₂</span>O, HCHO, H<span class="inline-formula">₂</span>O<span class="inline-formula">₂</span>, CH<span class="inline-formula">₃</span>OOH, C<span class="inline-formula">₂</span>H<span class="inline-formula">₆</span>, higher alkanes, alkenes, aromatics, NO<span class="inline-formula">_<i>x</i></span>, HNO<span class="inline-formula">₃</span>, HNO<span class="inline-formula">₄</span>, peroxyacetyl nitrate, and other organic nitrates), consisting of 146 494 distinct air parcels from ATom deployments 1 through 4. …”

Observations of cyanogen bromide (BrCN) in the global troposphere and their relation to polar surface O₃ destruction by J. M. Roberts, S. Wang, S. Wang, P. R. Veres, P. R. Veres, J. A. Neuman, J. A. Neuman, M. A. Robinson, M. A. Robinson, I. Bourgeois, I. Bourgeois, I. Bourgeois, J. Peischl, J. Peischl, T. B. Ryerson, C. R. Thompson, H. M. Allen, J. D. Crounse, P. O. Wennberg, P. O. Wennberg, S. R. Hall, K. Ullmann, S. Meinardi, I. J. Simpson, D. Blake

“…Liquid-phase reactions of <span class="inline-formula">BrCN</span> are more likely to convert <span class="inline-formula">Br</span> to bromide (<span class="inline-formula">Br⁻</span>) or form a <span class="inline-formula">C</span>–<span class="inline-formula">Br</span> bonded organic species, as these are the known condensed-phase reactions of <span class="inline-formula">BrCN</span> and would therefore constitute a loss of atmospheric active Br. …”
