Subsonic Assessment: Ozone and Nitrogen Oxide Experiment (SONEX) Data Archive

SONEX was conducted to understand a variety of NOx sources including the current subsonic aircraft fleet in the North Atlantic, with and without convection. To improve the models and our understanding, Photochemistry was collected to determine the impact of subsonic aircraft emissions on Tropospheric NOx and Ozone budgets. The experiment took place October - November 1997 from Bangor, Maine; Shannon, Ireland; and, Azores, Portugal.
