Resumen de Comment on “Missing gas-phase source of HONO inferred from Zeppelin measurements in the troposphere”
Chunxiang Ye, Xianliang Zhou, Dennis Pu
Li et al. (Reports, 18 April 2014, p. 292) proposed a unity nitrous acid (HONO) yield for reaction between nitrogen dioxide and the hydroperoxyl-water complex and suggested a substantial overestimation in HONO photolysis contribution to hydroxyl radical budget. Based on airborne observations of all parameters in this chemical system, we have determined an upper-limit HONO yield of 0.03 for the reaction.
