Description
Summary:Report discusses use of natural N2O as tracer gas in effort to determine large-scale lower stratospheric air flows during 1987 Airborne Antarctic Ozone Experiment. Data essential to understanding motions of air into and out of southern polar vortex and "ozone hole". N2O chosen as tracer because it has purely tropospheric sources, has troposheric lifetime greater than 20 years, and has long chemical lifetime in lower stratosphere.
