Overview

New dataset reveals spatial evolution of halogenated trace gases in the Arctic stratosphere, suggesting significant impacts on ozone.

Key Points

  • The study shows the vertical distribution of halogenated trace gases in the Arctic stratosphere.
  • Data collection involved a large balloon flight that obtained air samples using both AirCore and cryogenic techniques.
  • Results indicate comparable data quality for both sampling methods, with specific strengths and weaknesses identified.
  • Air samples highlighted air masses from the Asian Monsoon region and derived average stratospheric transit times.
