Short summary

We present direct measurements of the summertime total reactivity (inverse lifetime) of NO₃ towards organic trace gases at a rural mountain site. High daytime and low night-time values were found. The reactivity was dominated by reaction with monoterpenes and sufficiently high to compete with photolysis and reaction with NO during daytime. NO₃ radical measurements from one night are presented. For the first time, direct measurements of OH and NO₃ reactivity are compared.
