ABSTRACT: We describe the resources used, the deployment strategy, and the outcomes of the FRAPPÉ experiment, which took place in the summer of 2014 in the Front Range of Colorado. We provide a history of air quality of the region and the outcomes of previously conducted experiments, describe the atmospheric conditions encountered during the campaign, and summarize the scientific findings that the campaign produced, together with the DISCOVERAQ intensive, simultaneously carried out by NASA. The goal of FRAPPÉ was to measure emission tracers and photochemical tracers from the ground and by aircraft to be able to quantify the contributions of various emission sectors to the photochemical production of ozone in the Colorado Front Range. We found major contributions from the from the fossil fuel extraction sector as well as the transportation sector, with minor contributions from agriculture, energy generation and industry. The meteorological conditions were also found to be critical in creating situations conducive to high ozone in the area.
