A Characterization of RONO2 as a Sink for NOX in the Colorado Northern Front Range Metropolitan Area
Abstract
NOX (NO + NO2) is one of the primary contributors to the production of ozone. Ozone and alkyl nitrates are both produced during the oxidation of organic molecules during daytime. At night, organic nitrates are produced by reactions of NO3 with alkenes. Using measurements from the Colorado Northern Front Range Metropolitan Area in summer 2014 from the FRAPPE and DISCOVER-AQ field campaigns, we examine the production of alkyl nitrates during day and the influence of nighttime production on daytime concentrations. We discuss the relative roles of HNO3 and RONO2 as daytime termination steps in the NOx catalytic cycle and nighttime production of RONO2 as a sink of NOx.
