Short summary
This paper describes and presents results from a intercomparison, in an environment rich in NOx (i.e., NO+NO2), of two OH reactivity instruments: one based on the comparative reactivity method, and one based on the pump-probe method. Co-located measurements were made of both ambient air and standard mixtures. Ambient OH reactivity values measured by both instruments were found to be in good agreement for ambient NOx mixing ratios as high as 100 ppbv.
