In airsheds that contain high volatile organic compounds (VOCs) and low NOx (=NO+NO2) concentrations, ozone
(O3) production may be significantly suppressed by NOx reactions that lead to the formation of organic nitrates. O3 and
its precursors (VOCs and NOx) ambient levels simulated using a regional-scale photochemical model, called Multiscale
Air Quality Simulation Platform, are analyzed and compared to observed data from three southeast United States
national parks.
