Short summary
We describe the first instrument for measurement of the rate constant for reactive loss (i.e. the total reactivity) of NO3 in ambient air. This is essentially a measureement of the lifetime of NO3 and will help assess the role of NO3 and N2O5 in conversion of reactive nitrogen oxides to reservoir species in the troposphere.
