Abstract

The project POLINAT 2 was performed to investigate the impact of aircraft emissions on the state of the atmosphere over the North Atlantic, including the full range of the main flight corridir from Western Europe to North East America. The project icludes measurement and modeling tasks. Measurements have been performed from August to November 1997 using the instrumented research aircraft Falcon and an instrumented airliner B-747. The measurements include various nitrogen oxides,nitrous and nitric acids . Sulfur oxide and sulfuric acid, acetone, carbon dioxide, ozone, water vapour, carbon monoxide, aerosols, and meteorological parameters. The experiment was performed based on predictions of air mass trajectory and of chemical forwecasts. The measurements, which were performed in coordination with other experimental activities, included intercomparison flights. The modeling was done using existing and refined models for the atmospheric dynamics and chemistry on all scales from the engine exit to the globe. Direct intercomparisons have been performed between experimental data and chemical transport models. Plume models are used to investigate the conversion of emissions in the aircraft plume, including particle formation and interaction between a multiple of plumes from several aircraft. A global circulation model is used to compare with the statistics of nitrogen oxides and ozone measurements
