Short summary

Unknown sinks of OH and oxidation processes in the atmosphere have been attributed to what has been termed "missing" OH reactivity. Often overlooked are the differences in timescales over which the diverse measurement techniques operate. The effect of the sampling time and thus the contribution of unmeasured VOC variability on OH reactivity is investigated.
